FIRST LOOK: 'Hangover Part II' Trailer

The wolfpack is back!

The guys of 'The Hangover,' Bradley Cooper, Zach Galifianakis and Ed Helms, have regrouped and are taking their partying ways overseas to Bangkok.

"This is kinda nice, isn't it?" Zach's character Alan Garner, a.k.a. "wolfpack of one," says breathlessly as a monkey crawls on Cooper's shoulders and Helms appears to have a face tattoo. "The three of us back together again!"

The highly anticipated comedy 'The Hangover Part II' hits theaters May 26th.
