Chinatown (Special Collector's Edition)

Here's a classic noir (that means dirty movie set in the past) starring Jack Nicholson before he was simply known as Jack. Playing a seedy L.A. private eye, he gets sucked into a huge case involving the most powerful family on the West Coast and the water supply. It's one of those classics you've heard about but probably never saw. Even if you don't dig the movie, at least you'll now understand what Homer Simpson meant when he said: "Forget about it, Marge. It's Chinatown!"

Also available: The Two Jakes (Special Collector's Edition), which is the horrible sequel directed by Jack. This is like the opposite of Chinatown, except for a part where he pees on a guy. Or the guy pees on himself. Basically, the pee scene is pretty good.
