As promised yesterday, Warner Bros. has finally bestowed upon us the first trailer for The Hangover Part III, the franchise finale from director Todd Phillips. The Wolf Pack (Bradley Cooper, Ed Helms, Zach Galifianakis, Justin Bartha) is back together again, only this time, there is no wedding to rush back for, no missing groom to find. Set in both Los Angeles and Las Vegas, this trio must contend with some old friends (Ken Jeong's Mr. Chow, Heather Graham's Jade) and a host of new characters played by John Goodman, Melissa McCarthy, and many more. Check out the first footage for the last Hangover comedy.
