10 Sci-Fi Movies So Bad They Are Hilarious

5. Plan 9 from Outer Space

This movie is a poor attempt to combine aliens and zombies. Aliens come to Earth to turn the dead into zombies to help them defeat those darn humans. Oh, yeah, and they bring some vampires into the action, too. This one has a not very surprising theme with a predictable cast. If you’ve seen one zombie, you’ve seen them all. This one just has to be one of the worst sci-fi movies ever.


4. Zardoz


How many Sean Connery fans have heard of this one? Exactly. Seeing this big star in this sci-fi movie is enough to make fans cringe. Connery is an assassin among a group who worship a big stone named Zardoz. Yeah, that’s right. Some plot, huh? Connery does change his intent when he finds out Zardoz is not divine and is instead trying to destroy lowly mortals. How could Connery have known this flop would be one of the worst sci-fi films of all time?


3. Robot Monster


This movie is based on a dream—a clue that it’s going to be a bad movie—from a little boy picnicking with his parents. In his dream, this robot dude comes to bug his family and destroy the Earth. This monster is basically hidden away in a poorly made gorilla suit with an old diving mask to cover his head. Seriously, and this is supposed to scare us? Were they out of costumes in the prop room?


2. Frankenstein Conquers the World

Frankenstein Conquers the World

Dr. Frankenstein’s heart, which won’t stop beating outside his dead body, is stolen and taken to Japan. There, due to some weird radiation, it develops arms and legs and turns into a deformed boy who keeps growing larger and larger into a very huge and scary creature. People start calling him “Frankenstein.” This mutant boy goes around destroying everything and everybody in his way, until he meets up with a mutant reptile type of monster who wants to fight. They duke it out, as any viewer would expect in this horribly made film.


1. Lawnmower Man 2: Beyond Cyberspace


No, this movie isn’t based on the Stephen King story with the same name. Too bad it’s not. Maybe then it wouldn’t be the worst sci-fi movie ever. In this flop, this guy named Jobe has telepathic abilities which these evil scientists want to use to help them take over the world. Meanwhile, Jobe meets up with these teenage computer hackers who help him try to fight the scientists and their master plan. And what does a lawnmower have to do with anything? Not much, except for the fact that mowing grass was Jobe’s job before he was eyed by the mad scientists. This movie is about as exciting as mowing grass.
