Mike Tyson shows up listening to Phil Collins music in this hilarious trailer for The Hangover

Warner Bros. opens The Hangover – being directed by Todd Phillips (Old School, Starsky & Hutch) – on June 5th, 2009.

The Hangover follows three groomsmen who lose their buddy that’s about to be married, one day before his wedding, after driving to Las Vegas for a blow-out bachelor party. For some reason, when the three wake up the next morning, they find a tiger in the bathroom and a six-month-old baby in the closet of their suite at Caesars Palace. The one thing they can’t find is their friend Doug. With no clue as to what happened and little time to spare, the trio must retrace their hazy steps and all their bad decisions, in order to figure out where things went wrong and hopefully get Doug back to LA in time to tie the knot.

The Hangover stars Bradley Cooper, Ed Helms, Zach Galifianakis, Heather Graham, Justin Bartha and Jeffrey Tambor.
