The Wolfpack is back this Memorial Day Weekend as The Hangover Part III hits a movie theater near for the third and final time. Already promised to be bigger, badder, and funnier, this wrap-up to director Todd Phillips's comedic trilogy will have the boys return to Sin City where their misadventure all started first. As preparation for its premiere gets underway, studio Warner Bros. Pictures just released the first official poster for the film, featuring Alan Garner (Zach Galifianakis) facing off nemesis criminal mastermind Leslie Chow (Ken Jeong) against the backdrop of a Las Vegas in ruin. If it looks familiar, that's because its a parody on the poster of another Warner Bros. franchise, Harry Potter and the Deathly Hallows. With actors Bradley Cooper, Ed Helms, Justin Bartha, Zach Galifianakis, Ken Jeong, Jeffrey Tambor, Gillian Vigman, Sasha Barrese, Jamie Chung, John Goodman, plus the return of Heather Graham and Mike Epps, the Hangover Part III will in theaters on May 24th.
