The Hangover

Groom-to-be Doug (Justin Bartha, NATIONAL TREASURE) has planned an epic night in Las Vegas with his two best friends, Phil (Bradley Cooper, YES MAN) and Stu (Ed Helms, THE OFFICE), and his fiancée's awkward brother, Alan (comedian Zach Galifianakis). But it turns out that they partied a little too hard: Phil, Stu, and Alan wake up the next morning with a missing groom, a tiger in the hotel-room bathroom, a baby in the closet, and no memory of the night before.
