Don't watch these before going to bed!
From supernatural scenes to films based on horrifying real life events, the particular types of thrills audiences seek from a horror movie may have changed over the years — but some of these films from 50+ years ago are just as terrifying as they were on the day that they come out. It may not quite be Halloween yet, but it's never a bad time to queue up one of these spooky flicks.

Take a walk down memory lane by reliving some of the most influential scary movies — unless you have a little one nearby, then we would recommend watching a milder scary movie for kids instead.
