TRAILER: The Wolfpack Is Back to Burn Las Vegas Down in 'Hangover Part III'

Well, it looks like the promotional push for The Hangover Part III has finally begun. With the film less than three months away from hitting theaters, we had seen relatively little from it ... until yesterday, that is, when Warner Bros. released the film's first poster. The first trailer for The Hangover Part III hit the Internet today, giving fans of the franchise a look at what the final movie of the trilogy has in store for them.

Check out the trailer after the jump. The Hangover Part III hits theaters on May 24, 2013, with stars Bradley Cooper, Zach Galifianakis, Ed Helms, Ken Jeong and Justin Bartha returning. And, yes, it is a rule that every Todd Phillips film has to use a Wolfmother song.
