WATCH: The New Official Teaser Trailer for The Hangover 3

Bradley Cooper, Ed Helms, Zach Galifianakis, and director Todd Phillips are all returning for the third and final installment of The Hangover series.

The trailer shows our three heroes on a road trip that doesn’t appear to involve a wedding but rather Alan (Galifianakis) dealing with the death of this father (Jeffrey Tambor).

Justin Bartha, Ken Jeong, Jamie Chung, Heather Graham and Mike Tyson are all also back along for the ride.

So how do we think this one will go?
