10 Horror Movies Too Scary To Finish Watching

10. Black Sabbath (1963)

You might be thinking, "come on, a horror anthology movie from 1963? There's no way that's going to freak me out, not with my desensitised modern sensibilities", and to an extent, your (very self-aware) response would be correct. Black Sabbath is a classic horror that delivers three separate spooky tales, most of which won't keep you up at night. But, then, you'll arrive at the final tale, "The Drop Of Water".

This short segment is simple yet painfully effective. It follows a nurse who is given the task of preparing a dead body for burial. However, she soon becomes haunted by terrifying occurrences after stealing a ring from the corpse's finger.

Despite being nearly six decades old, the practical effects on display in this short have an unholy vibe that will haunt your nightmares. The infamous corpse the story centres around is brought to life with an uncanny grotesqueness that makes it easily one of the scariest dead bodies in all of horror. If anything, the movie's age only adds to the archaic terror.

As this monstrous object begins to animate itself and haunt the protagonist, you'll find yourself quaking in your boots and wishing for the whole experience to be over as quickly as possible.
