Directed by Todd Phillips and starring Bradley Cooper , Ed Helms , Zach Galifianakis , Justin Bartha , and Heather Graham . Two days before his wedding, Doug and his three friends drive to Las Vegas for a blow-out 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.
