“I told myself I would never come back,” Ed Helms’ Stu says at one point, but come back they do with predictably chaotic and mental results.

The third movie is directed and co-written by Todd Phillips, who’s been at the helm for the previous two installments.

Helms, Bradley Cooper, Zach Galifanakis return as the wolfpack, with Heather Graham and Ken Jeong reprising their roles and John Goodman and Melissa McCarthy along for the ride, too.

The Hangover Part III is due to be released May 24 through Warner Bros.
