This is a pretty messed up film from Canadian director Vincenzo Natali, but man, I do love it! It’s a winning combo of high-concept and low budget, but the story behind it is pretty terrifying.

In this film, a small group of strangers wake up in an elaborate prison maze made up of cubes, with traps, with no memory of how, or why, they’re there. Each cube is booby trapped and they need to learn to trust one another, but as the game goes on, they start to unravel. This one is a much watch if you have a soft spot for claustrophobic, psychological horror.
