Summer movie preview 2009

It must be a good sign they're already planning a sequel to "The Hangover"

Sometimes the best comedies are the ones you don't see coming (think "There's Something About Mary" or "The 40-Year-Old Virgin"), and the inside word is that "The Hangover" might be the next laugh-out-loud sleeper hit. Bradley Cooper, Zach Galifianakis and Ed Helms star in a very R-rated story of three groomsmen in Las Vegas who lose their buddy on the eve of his wedding. And yes, if audiences love it as much as the studio expects, there will be a follow-up in theaters before you know it.

Release date: June 5
