Doug (Justin Bartha) is the unsung hero of The Hangover Part II, but instead of glorifying his role in this upcoming comedy sequel from director Todd Phillips, Warner Bros. has released two new clips that feature the other three, lesser known members of the Wolf Pack: Alan (Zach Galifianakis), Stu (Ed Helms), and Phil (Bradley Cooper). To watch the boys discover that it has, in fact, 'happened again', check out these new clips below.
