Starring Bradley Cooper, featuring Heather Graham and Mike Tyson (yes, that's right - the ear biting boxer). Directed by Todd Phillips (Old School). Rated R for pervasive language, sexual content (including nudity), and some drug material. The run time is 100 minutes. This is a comedy about a bachelor party (well a bachelor trip, really, to Las Vegas) that spins way out of control. The groom-to-be and his three friends have a wild night in Vegas. The next morning, the groom-to-be is nowhere to be found, and his three friends cannot remember a thing about the previous evening. They need to locate the groom in time for the wedding, while trying to piece together the festivities of the night before. I don't think this film is going to make my top 50 list, but it is definitely worth watching, it is filled with laugh-out-loud moments. Very entertaining and funny. (It is actually one of the funniest movies I've seen, recently).
