Roman Polanski once said, "Cinema should make you forget you are sitting in a theater." And as one of the great filmmakers of suspense, his work always manages to transport you into a psychologically haunting place. And this week, the Criterion Collection is highlighting a handful of their favorite nail-biters for free on Hulu. From Polanski's classic black and white thriller Knife in the Water, to the Götz Spielmann's emotionally-gutting Oscar-nominated Revanche, here's what you should be watching this weekend from the psychologically terrifying to the charmingly haunting and all the goodies in between.
