100 worst sci-fi movies of all time

Quality science fiction cinema remains not just a visual document of mankind’s own potential, but an ongoing foray into the possibilities of the medium itself. The output in 2017 was naturally no exception, with entries like "Blade Runner: 2049," "Logan," and the upcoming "Star Wars: The Last Jedi" each exploring prescient human archetypes against a limitless expanse of imaginative terrains, situations, and characters. Even when dystopian vibes persist, audiences still exit the theater with their jaws agape. That’s the magic of sci-fi cinema. 

However, as compelling as great science fiction can be, terrible science fiction retains its own special place in the annals of cinematic history. Whether filled with clumsy acting, shoddy special effects, amateur directing or all of the above, bad sci-fi has become its own rich tradition complete with cult followings and midnight screenings. To think, there’d be no "Mystery Science Theater 3000" without these classic clunkers.

In celebration of campy sci-fi excess, Stacker has ranked the worst 100 sci-fi movies of all time. For the analysis, we’ve built an index (the Stacker Score) that combines IMDb ratings and Rotten Tomatoes Audience Scores. To qualify, a film needed to have at least 1,500 IMDb votes. Stacker Scores are based on a 1-100 scale; and now, we present the 100 worst sci-fi movies of all time.

#100: The Incredible Melting Man

Year released: 1977

Stacker Score: 31.50
IMDb User Rating: 3.9
Rotten Tomatoes Audience Score: 24%

He’s melting! He’s melting! So went the story of "The Incredible Melting Man," about an astronaut who returns from space and slowly degenerates into a murderous blob. The budget for this tone-deaf turkey was apparently so low that the producers couldn’t even afford stock footage of Saturn for the opening sequence, substituting public domain footage of the sun and a satellite moon instead. Shot in just fourteen days, the movie featured a cameo from future acclaimed director Jonathan Demme, possibly the best thing it had going for it.

#99: Double Dragon

Year released: 1994

Stacker Score: 31.50
IMDb User Rating: 3.7
Rotten Tomatoes Audience Score: 26%

1988 video game "Double Dragon"was a worldwide smash in arcades and on Nintendo systems. By contrast, 1994 movie "Double Dragon"was a cheesy box office dud that didn’t do the game’s legacy any justice. The movie took place in a futuristic wasteland and involved two brothers squaring off against an evil gang over a powerful Chinese medallion. To call the movie the quintessence of cheese would be putting it lightly.

#98: The Killer Shrews

Year released: 1959

Stacker Score: 31.00
IMDb User Rating: 3.8
Rotten Tomatoes Audience Score: 24%

Not to be confused with ill-tempered women made famous by Shakespeare, shrews are small rodent-like animals with long snouts and tiny eyes. In 1959’s "The Killer Shrews," the little creatures terrorize a group of people stranded on an island during a hurricane. For close-ups of the shrews, the director went with hand puppets. For long shots, he went with coon dogs. In spite of its poor reception and bad special effects, the movie actually turned a handsome profit for its time.

Threshold Entertainment / Midway Games

#97: Mortal Kombat: Annihilation

Year released: 1997

Stacker Score: 31.00
IMDb User Rating: 3.7
Rotten Tomatoes Audience Score: 25%

Awash with redundant action sequences, dated electronic music and wooden performances, "Mortal Kombat: Annihilation" was the paltry follow up to a much better first installment. The video-game based movie, which pitted a group of martial artists against extra-dimensional invaders, was so bad that game creator Ed Boon himself dubbed it the worst moment in the franchise’s history.

Herman Cohen Productions

#96: Trog

Year released: 1970

Stacker Score: 31.00
IMDb User Rating: 3.6
Rotten Tomatoes Audience Score: 26%

As anyone who saw FX’s "Feud"is likely to know, "Trog" was Joan Crawford’s final and arguably worst effort. In the film, Crawford played an anthropologist trying to communicate with a troglodyte dressed in an ape suit leftover from Kubrick’s "2001: A Space Odyssey." According to legend, Crawford provided her own wardrobe due to budget constraints, and later claimed she might have killed herself from embarrassment if not for a late stage conversion to Christian Science. In spite of all the terribleness, the movie was the top grossing film in the USA in its first week of release.

#95: Reptilicus

Year released: 1963

Stacker Score: 31.00
IMDb User Rating: 3.6
Rotten Tomatoes Audience Score: 26%

Big, prehistoric monsters commonly make for epically campy sci-fi movies. Take 1963’s "Reptilicus"for instance, a monster movie only worth watching for all the unintentional laughs. Among its other achievements in comedy was a quick appearance in a "South Park"episode (“Cancelled”).

Greenleaf Productions

#94: Dinocroc

Year released: 2004

Stacker Score: 31.00
IMDb User Rating: 3.1
Rotten Tomatoes Audience Score: 31%

Presented by Roger Corman, aka the king of B movies himself, was 2004’s "Dinocroc." It detailed the misadventures of a reanimated prehistoric crocodile that escapes from a lab, grows substantially and devours everything in its path. As one might expect, the film is an all-you-can-eat buffet of rough acting and cheesy special effects.

#93: C.H.U.D. II: Bud the Chud

Year released: 1989

Stacker Score: 30.50
IMDb User Rating: 3.8
Rotten Tomatoes Audience Score: 23%

1984’s "C.H.U.D."was a camp classic about a bunch of sewer-dwelling zombies. However, the 1989 sequel, "C.H.U.D. II: Bud the Chud," was dead on arrival. This time around, it’s a Chud named Bud chewing brains and spreading infections. Look for a cameo from scream king Robert Englund, and then put something better on.

#92: R.O.T.O.R.

Year released: 1988

Stacker Score: 30.50
IMDb User Rating: 2.4
Rotten Tomatoes Audience Score: 37%

With a story ripped straight out of "RoboCop," and VHS artwork ripped straight out of "Mad Max,"1988’s "R.O.T.O.R." was about as derivative as a movie could get. The cinematic tale of a cyborg crime fighter was executed so poorly that the screenwriter has since disowned it, laying all the blame squarely at the director’s feet.

11/
Marimark Productions

#91: Galaxina

Year released: 1980

Stacker Score: 29.50
IMDb User Rating: 3.5
Rotten Tomatoes Audience Score: 24%

As part of a genre that might be best dubbed “spaceploitation,” 1980’s "Galaxina"was a particularly inept movie about a voluptuous, 31st century android with feelings. The clunker was directed by the same man who made "The Incredible Melting Man"and famously starred Playboy centerfold Dorothy Stratten as the emotional robot.

Tragically, Statten was murdered by a jealous boyfriend the same year the film was released.

12/
Hollywood Pictures Corporation

#90: Carnosaur

Year released: 1993

Stacker Score: 29.00
IMDb User Rating: 3.5
Rotten Tomatoes Audience Score: 23%

Nothing quite captured the essence of straight-to-video schlock in the early to mid-90s the way "Carnosaur"did. Produced by Roger Corman, the "Jurassic Park"knock-off was shot in just 18 days with the cheesy visuals to show for it. Meanwhile, a healthy return on investment yielded some inevitable, and equally awful, sequels, at least one of which appears elsewhere on this list.

13/
New Line Cinema

#89: Pterodactyl

Year released: 2005

Stacker Score: 29.00
IMDb User Rating: 3.1
Rotten Tomatoes Audience Score: 27%

In the 2005 film "Pterodactyl," a bunch of dinosaur eggs hatched inside a remote volcano and gave way to pure cinematic garbage. Laden with poor CGI, the movie was made for lovers of schlock, who thereby watched it and skewered it with equal relish.

14/

#88: The Sand

Year released: 2015

Stacker Score: 28.00
IMDb User Rating: 3.8
Rotten Tomatoes Audience Score: 18%

When it comes to sci-fi and horror, virtually anything can be turned into a vicious antagonist. For proof of the fact, look no further than "The Sand," which featured the beach itself as a carnivorous monster. Shot in just twelve days, the movie was reportedly a remake of 1980’s "Blood Beach," as if that marginally better film warranted revisiting.

#87: World of the Dead: The Zombie Diaries 2

Year released: 2011

Stacker Score: 28.00
IMDb User Rating: 3.8
Rotten Tomatoes Audience Score: 18%

By 2011, zombie fever was more or less everywhere, which naturally led to a slew of poorly made zombie movies, each one vying for all the cash audiences could spare. Enter "The Zombie Diaries 2," a miserable excuse for a film that willed itself into existence on the heels of the slightly less terrible "Zombie Diaries." Rife with tacky violence and stilted performances, "Zombie Diaries 2"was appropriately brainless.

16/

#86: The Clonus Horror

Year released: 1979

Stacker Score: 28.00
IMDb User Rating: 3.4
Rotten Tomatoes Audience Score: 22%

Starring Peter Graves, "The Clonus Horror"was about a government experiment where politicians tried to clone themselves in order to achieve immortality. While the film did tout an intriguing premise, it nevertheless offered little more than standard B movie indulgence. Meanwhile, the director ended up suing 2005 Michael Bay film "The Island" for stealing "The Clonus Horror’s" storyline.

#85: The Adventures of Pluto Nash

Year released: 2002

Stacker Score: 27.50
IMDb User Rating: 3.8
Rotten Tomatoes Audience Score: 17%

Eddie Murphy was once an undisputed king of Hollywood, but "The Adventures of Pluto Nash"nearly sent him into exile. That’s in no small part thanks to the sheer terribleness of the comedic misfire, reportedly the biggest money loser in movie history. More than just a box office bomb, this movie was a nuclear explosion of epic failure.

#84: Beginning of the End

Year released: 1957

Stacker Score: 27.50
IMDb User Rating: 3.5
Rotten Tomatoes Audience Score: 20%

One might hear the words “giant killer grasshoppers” and already brace him or herself for some genuine cinematic schlock. Suffice to say, "Beginning of the End"lives up to the B movie hype. As it turned out, the real horror went down behind the scenes, whereas the 200 live grasshoppers used for the movie all ate one another, and were down to a dozen by the time filming ended.

#83: Killers from Space

Year released: 1954

Stacker Score: 27.50
IMDb User Rating: 3.1
Rotten Tomatoes Audience Score: 24%

Peter Graves made quite a career for himself starring in bad sci-fi movies, "Killers from Space"among them. In the film, Graves played a scientist and pilot who went missing after a mission, only to turn up later saying he was captured by the aliens. Was he telling the truth? Unfortunately, we may never know, since finding out would arguably require sitting through this dull mess of a film.

#82: Tale of the Mummy

Year released: 1998

Stacker Score: 27.00
IMDb User Rating: 3.8
Rotten Tomatoes Audience Score: 16%

Tom Cruise might have tanked in the latest attempt to rejuvenate the mummy franchise, but hopefully the failure of 1998’s "Tale of the Mummy" helps him sleep at night. The movie dealt with the typical mummy story in particularly inept fashion, duly running out of steam after a somewhat promising first act.

21/

#81: The Amazing Transparent Man

Year released: 1960

Stacker Score: 27.00
IMDb User Rating: 3.8
Rotten Tomatoes Audience Score: 16%

Years before "The Incredible Melting Man," there was "The Amazing Transparent Man." Part zombie movie, part HG Wells rip off, the film was about a mad scientist trying to establish an army of invisible zombies. The premise alone was brutal, and the execution naturally followed suit.

#80: S. Darko

Year released: 2009

Stacker Score: 27.00
IMDb User Rating: 3.6
Rotten Tomatoes Audience Score: 18%

2001’s "Donnie Darko"was not just an instant cult classic, but a prime slice of modern-day auteur filmmaking at its finest. That alone made follow up "S. Darko"—which didn’t involve "Donnie Darko"creator Richard Kelly at all—a blasphemous endeavor from the get-go. The fact that "S. Darko"also happened to be awful was like expired icing on an already rotten cake.

#79: The Giant Gila Monster

Year released: 1959

Stacker Score: 27.00
IMDb User Rating: 3.3
Rotten Tomatoes Audience Score: 21%

From Ray Kellogg, director of previously mentioned turkey "The Killer Shrews," came 1959’s "The Giant Gila Monster." The title pretty much spoke for itself, and audiences were presumably prepared for pure midnight movie madness. What they got in return was a normal-sized lizard destroying toy trucks and other blatant, miniature props.

#78: Village of the Giants

Year released: 1965

Stacker Score: 27.00
IMDb User Rating: 3.3
Rotten Tomatoes Audience Score: 21%

Filmed in “Perceptovision” (which was as gimmicky as it sounds), "Village of the Giants"was a tale about a bunch of teenagers who grow 30 feet tall and terrorize their town. It might sound like the stuff of teenage fantasy, but poor execution made it a largely forgettable endeavor. It did, however, feature some choice cameos from the likes of Toni Basil and Ron Howard.

#77: Carnosaur 3: Primal Species

Year released: 1996

Stacker Score: 27.00
IMDb User Rating: 2.9
Rotten Tomatoes Audience Score: 25%

The first "Carnosaur" was bad, and the third one was arguably worse. This time around, a group of terrorists receive an unexpected surprise when their cargo turns out to be filled with dinosaurs. The movie was originally a standalone film entitled "Primal Species," but ended up becoming part of the "Carnosaur" franchise. Such a move made perfect sense, given how awful both the film and the franchise were, after all.

American World Pictures (AWP)

#76: Batman & Robin

Year released: 1997

Stacker Score: 26.50
IMDb User Rating: 3.7
Rotten Tomatoes Audience Score: 16%

While largely a superhero flick, "Batman & Robin" took a turn into the sci-fi realm with two scientists named Mr. Freeze and Poison Ivy, who unleashed plenty of campy chaos in Gotham. Big budgeted films rarely get more silly and disappointing than "Batman & Robin."

China Star Entertainment

#75: Black Mask 2: City of Masks

Year released: 2002

Stacker Score: 26.50
IMDb User Rating: 3.6
Rotten Tomatoes Audience Score: 17%

The original "Black Mask"starred iconic martial artist Jet Li, and the franchise itself had nowhere to go but down in his absence. Accordingly, "Black Mask 2: City of Masks"was as stupid as it sounded, following the adventures of a genetically mutated superhero not played by Jet Li. Among Black Mask’s many powers was the ability to heal, yet no healing power in the world could put this mess of a movie back together.

#74: Ballistic: Ecks vs. Sever

Year released: 2002

Stacker Score: 26.50
IMDb User Rating: 3.6
Rotten Tomatoes Audience Score: 17%

Starring Antonio Banderas and Lucy Liu, 2002’s "Ballistic: Ecks vs Sever"was about two enemy agents who team up to fight a common foe. The movie truly fired on all cylinders of awfulness, replete with bad dialogue, bad acting and bad action sequences alike. So legendary was the terribleness of this dud that it’s considered the “worst reviewed movie of all time” on Rotten Tomatoes.

#73: Attack of the Giant Leeches

Year released: 1960

Stacker Score: 26.50
IMDb User Rating: 3.5
Rotten Tomatoes Audience Score: 18%

A swarm of giant killer leeches might sound like the stuff of nightmares, but the most horrifying thing about "Attack of the Giant Leeches"was primarily the film’s execution. Produced by Roger Corman’s brother Gene, the movie was shot in a mere eight days on a $70,000 budget. According to legend, Corman couldn’t afford to pay the camera grip enough extra money to go in the swamp water, and thereby did it himself. He grew sick as a result and even spent a few days in the hospital.

#72: Super Shark

Year released: 2011

Stacker Score: 26.50
IMDb User Rating: 2.5
Rotten Tomatoes Audience Score: 28%

With over 150 credits to his name, director Fred Olen Ray has released enough cinematic garbage to stink up a movie theater for days. However, 2011’s "Super Shark"was particularly rancid drek from the Olen Ray canon. The film was about a poorly rendered CGI shark with a penchant for eating people. In other words, it was about the same thing that all the other bad 2000s shark movies were about.

#71: Superman IV: The Quest for Peace

Year released: 1987

Stacker Score: 26.00
IMDb User Rating: 3.7
Rotten Tomatoes Audience Score: 15%

It’s safe to say that most franchises run out of steam by the fourth installment. For evidence, look no further than "Superman IV: The Quest for Peace," a failure in every imaginable way. In the film, Superman squared off against Nuclear Man in stunningly campy fashion. Christopher Reeve co-wrote the story, and yet that didn’t stop him from declaring it a “catastrophe from start to finish.”

#70: The Avengers

Year released: 1998

Stacker Score: 26.00
IMDb User Rating: 3.7
Rotten Tomatoes Audience Score: 15%

Before the Marvel Avengers that fanboys know and love today, there was a British TV spy series of the same name. In 1998, that series got a film of its own, and the results were spectacularly horrendous. Starring Uma Thurman and Ralph Fiennes, "The Avengers"was so bad that it was partly responsible for co-star Sean Connery leaving show business altogether a few years later (after another action film of his bombed).

#69: Santa Claus Conquers the Martians

Year released: 1964

Stacker Score: 26.00
IMDb User Rating: 2.5
Rotten Tomatoes Audience Score: 27%

The premise of 1964’s "Santa Claus Conquers the Martians"feels like something dreamt up by a bored ten-year-old in Sunday school. The movie was about poor, lonely martians who had no one to give Christmas presents to their children. To remedy their dire situation, the martians kidnap Santa Claus, naturally. In the end, Santa wins over the martians by bringing them holiday cheer.

Filmmaker Jesse Johnson apparently wrote the script for 2007’s "The Last Sentinel" while still in his teens. And it certainly showed. The movie, about a group of drone police who turn on their creators, featured martial arts legend Don “The Dragon” Wilson. However, that couldn’t save it from the doldrums of bad cinema history.

Super intelligent, genetically mutated bats have escaped from the lab and launched an attack on humanity, and it’s up to a local Sheriff to stop them. So went 1999’s "Bats," a movie that was marginally better than its poor reputation might suggest, but still pretty atrocious. To create the bats, the filmmakers use a combination of CGI, animatronics and two live bats imported from Indonesia.

Stacker Score: 25.50
IMDb User Rating: 3.6
Rotten Tomatoes Audience Score: 15%

With "Horror Planet," what could have been a respectable horror movie in experienced hands ended up as poorly received schlock. In the movie, a group of interplanetary archaeologists are under attack after one of them gets impregnated by an alien and turns into a homicidal maniac. Ultimately, the best thing going for this movie was a synth-based soundtrack and some cool retro box art.

Rotten Tomatoes Audience Score: 15%

Putting a clever spin on an urban legend, 1980’s "Alligator"was a relatively scary movie that earned a healthy cult following. However, the second time wasn’t the charm with "Alligator II: The Mutation." One of the movie’s many cinematic crimes was that didn’t give audiences enough alligator. Another was that it was just plain bad.

True to its name, "2001: A Space Travesty"was a travesty indeed. The poorly made comedy was zany in spirit only, and almost exclusively cloying for audiences. It starred Leslie Nielsen of "Naked Gun" fame, but he’d come a long way from his brilliant days as Lt. Frank Drebin.

Duly worthy of its appearance on "Mystery Science Theater 3000" is the low-budget Italian flick "The Puma-Man." Actor Donald Pleasence once referred to it as the worst movie he’d ever starred in, and that’s saying a lot because he’s been in some genuine stinkers.

If one ever needs a reason as to why Marvel ended up creating its own studio and taking matters into their own hands, look no further than 1990’s "Captain America." The story of a patriotic super-soldier unfrozen from ice and sent into battle had never looked so bland. Rumor has it that production was a fiasco from the get-go, with constant financial difficulties. That said, supposedly Stan Lee was a big fan of the movie.

In the mid-1980s, zombies were given new life and even some comedic breadth with the cult classic, "Return of the Living Dead." How that ultimately led to 2005’s "Return of the Living Dead: Rave to the Grave"is anyone’s guess. The movie—about a college campus drug that accidentally wakes the dead—reeked of straight-to-video production and bad special effects.

Shot in six days and made for just $37,000, 1968’s "The Astro-Zombies"was about a mad scientist who creates a body, which ends up going on a killing spree. In spite of being one of the worst movies ever made, the film does retain a certain vintage allure, which is perhaps why rock band Misfits named a song after it.

Director Bob Clark was responsible for notable classics like "A Christmas Story and Porky’s," which means he gets a pass for the "Baby Geniuses"franchise. The original ranks among famous critic Roger Ebert’s most hated movies all time, and with good reason. While the babies are super intelligent, the same can’t be said for the film.

Directed by B movie horror legend Charles Band, and starring a young Demi Moore, 1982 sci-fi flick "Parasite" was a box office success in spite of its ineptitude. In the movie, Moore helps the protagonist eradicate a deadly parasite from his stomach before it kills him. The film—while predictably lackluster—was referenced in a slew of subsequent movies and the 1988 video game "Splatterhouse"as well.

As part of a series, "War of the Colossal Beast" continued the misadventures of “The Amazing Colossal Man,” a military man who grows in size after being exposed to radiation. They thought he was dead after he took a spill in the Hoover Dam, but as it turns out in this installment, he’s alive, disfigured and hungry. The movie was in black and white except for the last minute, which was in color for some reason.

Fans of the "Return of the Living Dead"franchise saw "Rave to the Grave" and said, “It can’t get any worse.” To which "Necropolis"replied, “Hold my beer.” Needless to say, this particular story of zombies run amok was horrifically inept, even when compared to bad zombie movies.

"Battle for Skyark"was a recent film set on a future Earth, where an orphan flees from monsters while discovering he has a greater purpose in the world. The movie tried to make the most out of its $2.5 million budget but ultimately fell far short of any conceivable goal. Unless, of course, the film’s goal was to end up being reviled by audiences and critics alike.

Cuba Gooding Jr. once said “show me the money,” and we’re assuming that’s exactly what got him on board for "The Devil’s Tomb," a 2008 crash course in bad filmmaking. Along for the ride were other reputable talents like Henry Rollins and Ron Perlman, who couldn’t save the thriller from being a meandering, poorly made mess.

After getting the electric chair and being subsequently reanimated, Charles “The Butcher” Benton seeks revenge on those who crossed him in the "Indestructible Man." Famous character actor Lon Chaney Jr. played the lead role and spoke no dialogue after an early scene. This vintage pile of cinematic junk was double-billed with the far superior "Invasion of the Body Snatchers" and looked all the worse by comparison.

It was larger-than-life actor John Huston versus a larger-than-life mutant octopus in 1977’s "Tentacles." According to legend, the production team dropped loads of cash for a giant prop octopus just to watch it drown at sea on its first day. From a quality perspective, the movie would soon follow suit.

Nowadays, James Cameron might be one of the most formidable names in Hollywood, but in the early 1980s he was a young Roger Corman protege helming "Piranha Part Two: The Spawning." Well, sort of helming it. Apparently, it was a producer Olivio G. Assonitis who really directed most of the film, something Cameron was all too eager to admit to later on. Meanwhile, when in Rome for the movie’s debut, Cameron dreamed up the idea for "The Terminator." He hasn’t answered to anyone but himself since.

Once a heartthrob and respectable actor, Christian Slater found himself "Stranded" in a 2013 film of the same name.

People might not remember it, but basketball star Shaquille O’Neal enjoyed a short-lived acting career at the height of his fame. In "Steel," he played a weapons designer whose creations end up in the wrong hands. During production, Shaq was forced to do his own stunts because they couldn’t find a stunt double who matched his height. In spite of all that extra effort, the movie stank big time. Barring future cameos as himself, "Steel" was more or less the end of Shaq’s mainstream acting career, which was probably for the best.

When it comes to campy midnight movies, no premise is too ridiculous to digest. But when a commercial film drops about Whoopi Goldberg and a talking dinosaur teaming up to fight crime in a futuristic society, some genuine head scratching is practically obliged. In the case of "Theodore Rex," that head scratching came from Goldberg herself, who tried with all her might to get out of her contract to no avail. Expectedly, the film tanked, and Goldberg’s career was never quite the same.

Loosely based on a short story by Stephen King, the original "Lawnmower Man"was an uneven but ultimately prescient film about the dangers of technology. "Lawnmower Man 2: Beyond Cyberspace," on the other hand, was so shockingly inept that its faults overshadowed any sense of thematic urgency. The movie saw digital demon Jobe trying to connect all the computers in the world into one network, a premise that certainly sounds timely enough even by today’s standards. Unfortunately, it was pure amateur hour behind the scenes, and the only warning shots fired were on the dangers of bad filmmaking.

Not only was the schlock factory responsible for the popular "Sharknado" franchise, but they’re behind a number of films on this very list. It’s therefore no surprise to discover that The Asylum produced 2005’s "King of the Lost World,"a "King Kong" knock-off that skirts around its own derivation by going straight to the source. That is, the movie takes its name from "The Lost World," a story by Sir Arthur Conan Doyle that apparently inspired a slew of monster island movies in its wake. Hence, "King of the Lost World"scores one point for doing its homework and then fails miserably on every other front.

1965’s "Monster a-Go Go"—about a creature from space who assumes the identity of an astronaut—actually began filming in 1961 with Bill Rebane in the director’s chair. About halfway through filming, Rebane ran out of money and was thereby forced to shut down production. Years later, a different director named Herschell Gordon Lewis bought Rebane’s footage and ended up finishing the movie. However, because Lewis was unable to secure a number of the original actors for the extra shoots, many of the characters simply vanish in the middle of the film itself.
