10 Cheesy Sci-Fi Movies To Watch On Prime Video

Prime Video has a huge selection of movies and shows, and while it includes both classics and some real duds, these 10 science fiction films are currently among the most fun to watch. They might not be high art, but they’re definitely entertaining!

Prime Video is a fantastic place to find science fiction movies, offering both hidden treasures and delightfully cheesy options. From classic, low-budget monster movies of the 1950s to more recent, over-the-top action sci-fi, it’s a valuable streaming service for fans who enjoy a bit of fun and aren’t afraid to embrace the less polished side of the genre.

Sometimes, a delightfully bad science fiction movie can be more fun than a truly good one. This is often because the unintentional humor adds an extra level of enjoyment. The best bad movies are sincere efforts – they need to be the result of a filmmaker genuinely trying (and missing the mark) to create something amazing. If a movie knows it’s silly and tries to be funny, it just doesn’t have the same charm.

This list features 10 delightfully cheesy science fiction movies from across different eras and styles. While many of these films were once quite good, they’ve become a little silly over time. What they all share is that they’re still fun to watch, even with their over-the-top moments and campy charm.

10. Earth Vs. The Spider (1958)

Bert I. Gordon’s Earth vs. the Spider is a classic, delightfully campy sci-fi film from the golden age of the genre. The movie features a giant spider terrorizing a small town, emerging from a cave to prey on people. What sets it apart from other monster movies of the time is that the spider’s enormous size isn’t explained by any scientific reason – it just is.

Honestly, this movie is just plain fun! The acting is over-the-top and the special effects are hilariously bad, but that’s part of what makes it so great. And the ending? Classic monster movie mayhem! I know Earth vs. the Spider is famously cheesy – it even got the Mystery Science Theater 3000 treatment – but even without the commentary, it’s a really enjoyable watch on Prime Video. I highly recommend it if you’re looking for a good laugh and some retro monster action!

9. Battle Beyond The Stars (1980)

Despite being largely forgotten, Battle Beyond the Stars is a fun, if silly, sci-fi movie from the 1980s. Produced by Roger Corman, it’s essentially a low-budget take on Star Wars, telling the story of a young hero who needs to hire a team of mercenaries to save his world from a ruthless dictator. While made on a shoestring budget, the film is surprisingly inventive and doesn’t hold back on its creativity.

While the special effects aren’t bad for a film from the 1980s, and it stars well-known actors like Robert Vaughn and Richard Thomas, Battle Beyond the Stars definitely shows its low budget in places. There are some truly silly scenes, but that’s part of what makes this ambitious, flawed movie so entertaining.

8. Hell Comes To Frogtown (1988)

Featuring wrestling icon Rowdy Roddy Piper, Hell Comes to Frogtown is a truly bizarre sci-fi film that you have to experience to believe. Set in a future where most people can’t have children, the movie follows a man sent on a strange mission: to rescue fertile women from a fortress inhabited by frog-like humanoids. It’s a deliberately silly and over-the-top film that embraces its ridiculousness.

Despite a premise that seems like it should be funny, Hell Comes to Frogtown takes itself surprisingly seriously. The jokes don’t really land, and the movie is actually funniest when it’s not trying to be. The acting is wildly exaggerated, and the frog-headed bad guys are a highlight. It’s not a good movie, but it’s certainly entertaining.

7. Destroy All Monsters (1968)

By the late 1960s, the Godzilla movies became more lighthearted and over-the-top. Destroy All Monsters features a huge cast of monster fighters, including Godzilla, Mothra, and Rodan, along with many other Japanese creatures, all battling it out. The movie barely focuses on the human characters, letting the monster action take center stage.

While Destroy All Monsters is definitely one of the most delightfully silly Godzilla films, it’s hard not to love. It delivers exactly what many fans of giant monsters want: tons of battles between the famous, rubber-suited creatures. Prime Video has a good selection of classic kaiju movies, but Destroy All Monsters is essential viewing.

6. Timecop (1994)

While many consider Timecop to be one of Jean-Claude Van Damme’s best films, it’s also undeniably a bit cheesy. The story follows a time agent who must prevent alterations to history, but a crooked politician threatens his family. It’s a straightforward, over-the-top, and wonderfully campy action movie that perfectly captures the spirit of 1990s cinema.

Jean-Claude Van Damme’s fighting abilities are on full display, and the movie delivers plenty of action for fans of the genre. While it’s a science fiction story, the plot is surprisingly smart, and Timecop holds up better than many films from that era. If you’re feeling nostalgic, it’s definitely worth watching now that it’s available on Prime Video.

5. At Earth’s Core (1976)

Unlike most science fiction films of the 1970s that focused on space, At Earth’s Core took a different approach. The story follows a Victorian-era inventor who builds a giant drill to tunnel deep beneath the Earth’s surface. There, he discovers a civilization of people plagued by terrifying creatures. Despite being released in 1976, the movie has a visual style reminiscent of 1950s science fiction films.

This charmingly old-fashioned British-American film feels like a classic from a classic era. It’s inspired by the imaginative science fiction of authors like Edgar Rice Burroughs and Jules Verne, offering a glimpse into sci-fi’s past. While Peter Cushing gives a strong performance, even he can’t prevent At Earth’s Core from becoming a bit silly at times.

4. Trancers (1984)

Many science fiction fans haven’t discovered the 1984 film Trancers, but it’s a really enjoyable movie. It’s about a time-traveling agent who comes to Los Angeles to stop a man with the ability to turn people into zombies. This cult classic from Charles Band throws a lot of different ideas together, creating a unique sci-fi experience.

Trancers mixes time travel with hard-hitting action, and while it’s made on a low budget, the story itself is surprisingly good. It’s definitely a bit cheesy at times, but if you’re looking for a hidden sci-fi gem on Prime Video, you should check out Trancers.

3. Hardcore Henry (2015)

I recently checked out Hardcore Henry, and it’s definitely pushing the boundaries of sci-fi – though it leans into the delightfully cheesy side of things. The story is pretty classic: a guy gets brought back to life with some serious cybernetic upgrades and has to rescue his wife from a world-ending villain. What really sets this movie apart, though, is that it’s filmed entirely from the main character’s point of view – it’s a total gimmick, but a surprisingly fun one!

Hardcore Henry is a wildly over-the-top, strange, and ambitious film that really tried to push the boundaries of filmmaking. While its unique style didn’t become popular, it remains a fun and memorable piece of 2010s cinema. Just don’t expect a sensible sci-fi plot, and be warned – it might make you feel motion sick!

2. Nemesis (1992)

I remember 1992 being an amazing year for science fiction, and Nemesis really stood out. The movie follows a cyborg police officer who has to hunt down his old partner – he’s teamed up with a group of hackers and information terrorists. It’s definitely got a Blade Runner vibe, but Nemesis is Albert Pyun’s take on that classic, done with a much smaller budget.

While Nemesis sometimes tries to do more than it can realistically achieve, resulting in some cheesy special effects, it’s skillfully directed. Pyun manages to create a lot of excitement despite the film’s limitations. It’s a perfect, undemanding action movie – you can easily enjoy it without thinking too much. It’s full of action and wonderfully earnest, which is exactly what makes a fun, low-budget sci-fi film work.

1. Freejack (1992)

Starring Mick Jagger of the Rolling Stones, Freejack is a unique and memorable film from the 1990s. The movie is set in a future where wealthy individuals hire mercenaries to travel back in time and kidnap young, healthy people – hoping to transfer their consciousness into these younger bodies. The story follows one of these kidnapped individuals as he fights to survive in this strange future.

The idea behind this movie is surprisingly cool, but it’s executed in a really over-the-top, campy way. Featuring Mick Jagger alongside Anthony Hopkins and Emilio Estevez, it’s a surprisingly well-made, if somewhat silly, film. Critics weren’t wrong about its flaws, but those flaws are actually part of what makes it fun. If you’ve already watched all the best sci-fi on Prime Video, this cheesy option might be worth a look.
