Leonardo DiCaprio has once again teamed up with Martin Scorsese, but this time the result is a little bit different from what you'd expect. Shutter Island concerns the strange goings-on at an Alcrataz-like institution for the criminally insane off the coast of New England. Along with Mark Ruffalo, DiCaprio plays a U.S. Marshal sent to investigate the bizarre disappearance of a murderess from the fortress-like hospital, which also happens to be run by the one and only Sir Ben Kingsley. Based on a novel from crime writer extraordinaire Dennis Lehane, this one is bound to send a chill or two down your spine.
