THE LAST SUPPER- It's got a ton of cameos: Cameron Diaz, Jason Alexander (from Seinfeld), Bill Paxton. It's about a bunch of liberals that invite an ultra conservative to dinner once a week and try to change their political views. If they don't succeed, they kills the person. Such a great, dark movie and has much more significance to me in this political day and age.
Also, I'd have to recommend RAISE THE RED LANTERN. It's a Chinese film about a man who has five wives. When he chooses to spend the night with a particular wife, red lanterns are raised in front of her house and she is granted extra privileges the next day. The women begin plotting and manipulating each other in order to be granted the red lantern for the evening. It's truly a must see.
