Full 'Hangover 2' Trailer Shows Lots of Familiar Faces

The Hangover Part 2 cuts Liam Neeson cameo

The comedy hit of 2009, The Hangover, introduced us to four friends who hit a little snag in Las Vegas in a last-minute stag party. Losing their soon-to-be-wed best friend during a drunken adventure, the three groomsmen - played by Bradley Cooper, Ed Helms and Zach Galifianakis - attempt to retrace their steps and hilarity ensues, boosted by a surprise cameo of Mike Tyson.

Two years later and the guys (now dubbed "The Wolfpack") are back for The Hangover Part II and this time, they're off to Bangkok for another misadventure, again directed by Todd Phillips, but this time somebody else gets lost.

The Hangover Part II teaser trailer debuted just over a month ago and did nothing but revisit the characters, letting the details of their appearance alone bring back the best comedy bits of the first film. It was simple and it worked. Today, the first full trailer premiered at CinemaCon and Apple has released the HD version online.

Watch and enjoy the full new trailer for The Hangover 2:

Head to Apple for the HD trailer.

From the trailer it appears Justin Bartha has a larger role now that he's not the character who's lost, and jumping into what seems to be more of a lead role is Ken Jeong, who had a minor part in The Hangover. The Hangover Part II also sees the return of Mike Tyson (likely responsible for Stu's new facial tattoo) and special cameo appearances by Liam Neeson, Paul Giamatti and President Bill Clinton. Jamie Chung (Sucker Punch) joins the cast as Stu's fiance.
