10 Forgotten Sci-Fi Horror Movies That You Need To Watch

10. Lifeforce

Vampires in space. Do you need any more convincing?

There have been plenty of ludicrous concepts in horror movies, but this one goes above and beyond to put them all to shame. It was hardly a classic in the making upon its release, but the campy, practical effects-filled, B-movie flick is one that you don't want to miss out on.

Lifeforce is based on a novel titled "The Space Vampires" and tells the story of a collection of astronauts who salvage three humanoid figures from a space wreck. But, their act of charity backfires as they are actually vampires who suck the life force out of the crew before making their way to Earth.

The film has gone on to attain cult status, and it's not surprising. It's a bombastic and ridiculous flick filled with violence, nudity and dated VFX. The combination of science fiction and vampire mythology is also a deliciously campy blend, which feels both ludicrous and well-thought-out at the same time.

Thanks to the goofy concept, strong visuals, and ridiculous writing, you'll have an absolute blast watching it.
