I'll admit that I hate it when Hollywood makes a popular movie into multiple movies that are all the same just to cash in. And at first that's what it looked like they were doing with "The Hangover" franchise. But these movies rule, so it's ok.

Mr. Chow is back, the boys are back in Vegas, Heather Graham is back, and a giraffe is decapitated. And that's just in this trailer! Watch it and feel the tingle rise from below...this should be epic!
