Two days before his wedding, Doug (Justin Bartha) and his three best friends Phil (Bradley Cooper), Stu (Ed Helms), and Alan (Zach Galifianakis) drive to Las Vegas for a blowout bachelor party they'll never forget. But, in fact, when the three groomsmen wake up the next morning, they can't remember a thing. For some reason, 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 Doug. With no clue as to what transpired 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 Los Angeles in time to walk down the aisle. We recently caught up with the funny folks behind The Hangover, this summer's wildest comedy.
