Classic Sci-Fi Horror Films

Experience the terror of killer kids and a treacherous train with classic sci-fi horror films.

Little mutant killer children scare us. A group of women that kill men after being intimate with them also instills fear in us. Regardless of your fear tolerance, sci-fi horror films are one of the most terrifying horror film genres in existence. Alien deals with a violent extraterrestrial life form that is out to kill others, while Demon Seed depicts a super smart AI that wants to pass on its intelligence through a human child by means of his creator's wife. No matter what gets you covering your eyes on a scary movie night, the mixture of horror and sci-fi movies has been a recipe for both terror and success for decades. The potential of these scenarios actually occurring combined with the gore and horror of the events makes for movies that will have fans for years to come.
