Cube

If M. C. Escher were alive to make a horror film I'm pretty sure it would look pretty much like CUBE. One of the most unique concepts to ever come down the pipeline, CUBE finds seven strangers, each with different strengths, stranded inside of a giant shifting cube full of rooms, many of them laden with unique ways to die. Nevermind how or why they are there, they simply have to try and get out and this is when the fun begins. Vincenzo Natali simply does an amazing job directing a relative cast of unknowns here and it is this very fact which makes CUBE so disturbing. Had he used faces you recognized the effect would not be as unsettling. Mind you, Nicole de Boer from Star Trek: Deep Space Nine but you won't twig to it quickly. Come to think of it, the netire cast is comprised of very well travelled character actors so you may find yourself scratching the head wondering "hey, where do I know this person from" but the action and dialogue is so tight I don't think this will be a problem. Answers, on the other hand, may be in short supply. Perhaps you might wish to follow this up with a reading of HOUSE OF LEAVES.
