The Wolf Pack has gone rogue in the first red band trailer for The Hangover Part III. Watch Bradley Cooper as Phil, Zach Galifianakis as Alan, and Ed Helms as Stu lose their friend Doug (Justin Bartha) to a gangster (John Goodman) with a limited amount of time on the clock left to save his life. They must traverse Las Vegas and Mexico to find their old friend Chow (Ken Jeong) and restore balance to the universe. Tread carefully, it gets nasty (no one under 18 is allowed to watch without an adult present)! Click on Alan to watch now...
