The first teaser trailer (and poster, which you can see above) for The Hangover Part II has arrived, announcing that The Wolfpack Is Back, with Bradley Cooper, Ed Helms and Zach Galifianakis getting into more endless scrapes and trouble when they travel to Thailand for Stu’s wedding. While Stu thinks he’s sorted it out so it’ll be nothing like the Vegas debacle, of course things soon get out of hand. It hits cinemas on May 27th, but click below for the teaser, which doesn’t play out like you’d expect for what will be an anarchic comedy. However with the first film having grossed $467 million, Warner don’t need to worry that a lot of people want to see more.
