Best Sci Fi Horror Movies

Every genre brings something different to the table, but sci-fi horrors will always intrigue people around for bringing the spotlight on to the much needed scary element. Down the years many films have horrified yet attracted viewers from all over the globe. We will countdown to a compiled list of top 30 best sci fi horror movies of all time:

 

30. The Purge (2013)

The Purge 2013 Sci-Fi Horror Movie

This movie surrounds a not too distant future, the government has established a yearly 12-hour period in which all crime is legalized.

It is a very intriguing flick with a pretty fascinating concept, yet does have some underwhelming execution as the story primarily focuses on a single-family going through this horrifying event.

 

29. Plan 9 from Outer Space (1959)

Plan 9 from Outer Space 1959 Horror Movie

An odd concept for a film, as some Aliens bring human beings back from the dead into zombies and vampires, in order to stop humanity from building a bomb that is powered by the sun. It’s definitely a very interesting film to view though.

 

28. Pitch Black (2000)

Pitch Black 2000 Movie

A space transport vessel and its crew are left stranded on a planet where there are dangerous monsters who only come out during the night to feast on their prey.

The situation seemed hopeless until the crew finds Riddick, played by Vin Diesel, to be their last hope of survival. A very intense horror Sci-fi with certain action set pieces thrown here and there.

 

27. Life Force (1985)

Life Force (1985)

A group of vampires, from space, who arrive in London and start infecting the local population and transform them into zombies.

The concept alone should peak your interest, but it is supported by the over the top horrific elements that are seen.

 

26. Predator (1987)

Predator 1987 Sci Fi Movie

A team of commandos is on a rescue mission in the South American Jungle, where a helicopter crashed. However, the team finds itself under attack by a strange extra-terrestrial creature that started hunting them down and murdering them one by one.

Starring a pretty bad-ass cast of characters played by Arnold Schwarzenegger and Carl Weathers, it includes a lot of action that is complemented by a very vigorous atmosphere.

 

25. The Blob (1988)

The Blob (1988)

An alien jelly-like creature that keeps on growing as it consumes everything in its path. An extremely horrific experience as the mere presence of this faceless creature, that seems to have no weakness, eats everyone and everything in its way.

It’s definitely one of the scariest sci-fi movies from the 80s.

 

24. Bad Taste (1987)

Bad Taste (1987)

Directed by Peter Jackson, the filmmaker who also directed The Lord of the Rings and The Hobbit trilogy, the entire population of a small village is eradicated and replaced by literally big-headed aliens who search for human flesh for their intergalactic fast-food chain.

Very goofy in terms of looks but does tend to give a vibe as something dark and sinister.

 

23. Night of the Creeps (1986)

Night of the creeps 1986

Due to an alien experiment, these alien brain parasites are created that try to turn their hosts into mindless zombies and spread the infection further.

Very basic in concept but executed well in terms of expressing the horrors of the situation.

 

22. They Live (1988)

They live 1988 Movie

A construction worker comes across a pair of sunglasses that, in a manner of speaking, help him see the truth in the world.

What is the truth? Well that is something that I feel like you should watch the film to find out as it leads to very horrific events and even some mild satire of the world as we know it even now.

 

21. eXistenZ (1999)

Best Sci Fi Horror Film eXistenZ 1999

A game designer, who is targeted by a group of assassins, is forced to test her virtual reality game to observe whether the game is damaged or not.

 

20. From Beyond (1986)

From Beyond (1986)

Some scientists develop the resonator, which is a device that can help humans witness essentially what is beyond their visible reality.

However, things take a turn for the worst as they are attacked by these unknown life forms after the experiment succeeds. You can have a lot of entertainment from a story like this and it does pull its punches when it comes to the scares.

 

19. The Thing (1982)

The Thing (1982)

Directed by the veteran horror movie director, John Carpenter, an expedition of scientists to Antarctica promptly gets unpleasant as they find out that a shape-shifting alien that takes the appearance of the creature it kills is after them.

It’s one of the best classic sci-fi horror movies ever and takes full advantage of the snowy environment it is in, which helped build up tension in the air and an all-around sense of danger throughout.

 

18. Videodrome (1983)

Videodrome 1983

A disreputable TV-Programmer acquires a new type of programming for his station, which leads his life and the future of media to go bonkers.

Though the horror parts of the film are done well but it does end up feeling a bit stale in terms of how the characters interacted with one another.

 

17. The Mist (2007)

The Mist 2007 Movie

An unpredictable storm hits a town and unleashes a weird species of monsters. Thus, a small group of people are held up in a supermarket to fend for their lives.

The real point of the film is to show what extremes even the most normal people will take when their lives are at stake. Despite the fact that the film features one of the most tragic endings in cinematic history, it’s still one of the most enjoyable sci-fi alien movies ever.

 

16. 28 Weeks Later (2007)

28 weeks later 2007 Movie

28 weeks after the rage virus had infested in the population of Great Britain, the US Army steps in to salvage a few survivors in a small section of London, in order to repopulate and start again.

However, things don’t exactly go according to plan. It promises to be one of the greatest horror movie sequels ever put to film.

 

15. Slither (2006)

Slither (2006)

A small town is infested with humans turned to mutant-like zombie creatures, due to some alien plague overtaking the place.

Filled with a very charismatic cast, including the likes of Nathan Fillion and Elizabeth Banks, it’s very well complimented by the talented Guardians of the Galaxy (2014) director, James Gunn.

13. Tremors (1990)

Tremors (1990)

Locals of a small and mostly barren town are forced to defend themselves against weird worm-like creatures that live underground.

The horror in the film really comes from the vigorous environment as the creatures could literally come out from anywhere. It’s really fun to watch a film with a great science fiction plot.

 

12. Cloverfield (2008)

Cloverfield 2008 Best Sci Fi Horror Film

This found footage movie is basically Godzilla, but in the form of horror, as we literally only see the human-perspective of the monsters attack on the city through the found footage.

One thing this film does well is its usage of the monster as its face is never shown until the end and is mostly never onscreen to help build up its presence. It definitely stands amongst the best-found footage movies of all time.

 

11. Scanners (1981)

Scanners (1981)
