Bradley Cooper, Zach Galifianakis, Ed Helms and Justin Bartha are all returning along with Ken Jeong. The official synopsis for the film is:
This time, there’s no wedding. No bachelor party. What could go wrong, right? But when the Wolfpack hits the road, all bets are off.
Ahead of the release a teaser poster has been released that parodies Harry Potter and the Deathly Hallows. Take a look at the poster below and watch the trailer above.
