The Hangover gang is back in a new trailer for the sequel to 2009’s hit comedy about three groomsmen who lose their about-to-be-wed buddy during their drunken misadventures.

The Wolf Pack, Stu (Ed Helms), Phil (Bradley Cooper) and Alan (Zach Galifianakis) start a bachelor party. But this time, they wake up in exotic Thailand, without a clue how they got there or any memories of the night before.

Why mess with a proven formula, right?

Liam Neeson makes a cameo in the film, replacing Mel Gibson. He was bounced from the picture after the cast protested following his outburst with ex-girlfriend.

Former Heavyweight boxing champion Mike Tyson, returns in the sequel, after his surprise appearance in the first film proved to be highly popular addition.

In the sequel, the boys wake up from their roofie binge to discover Alan with a shaved head, while Stu wakes up in a bathtub with a Mike Tyson-like face tattoo.

That’s basically all they have to go on to piece together the previous night.

The film hits theaters on May 26th. Check out the trailer below.
