Now this is what I'm talkin' about. "The Hangover" is a funny movie, flat out, all the way through. Its setup is funny. Every situation is funny. Most of the dialogue is funny almost line by line. At some point we actually find ourselves caring a little about what happened to the missing bridegroom -- and the fact that we almost care is funny, too.
The movie opens with bad news for a bride on her wedding day. Her fiance's best buddy is standing in the Mojave Desert with a bloody lip and three other guys, none of whom is her fiance. They've lost him. He advises her there's no way the wedding is taking place.
We flash back two days to their road trip to Vegas for a bachelor party. Doug, her future husband (Justin Bartha), will be joined by his two friends, the schoolteacher Phil (Bradley Cooper) and the dentist Stu (Ed Helms). Joining them will be her brother Alan (Zach Galifianakis), an overweight slob with a Haystacks Calhoun beard and an injunction against coming within 200 feet of a school building.
The next morning, Doug will be missing. The other three are missing for several hours; none of them can remember a thing since they were on the roof of Caesars Palace, drinking shots of Jagermeister. They would desperately like to know: How in the hell do you wake up in a $4,200-a-night suite with a tiger, a chicken, a crying baby, a missing tooth and a belly button pierced for a diamond dangle? And when you give your parking check to the doorman, why does he bring around a police car? And where is Doug?
