Last seen together in Starsky and Hutch, Vince Vaughn and Owen Wilson members of the so dubbed Frat Pack whose fraternity also includes Will Ferrell, Jack Black, Ben Stiller and Luke Wilson reunite for the romantic comedy, Wedding Crashers.

Divorce mediators and lifelong friends, Jeremy Klein (Vaughn) and John Beckwith (Wilson) have dreamed up a unique way of meeting women they crash a different wedding every week. With strict rules to guide them and in an atmosphere in which romance is very much the mood of the moment, the two guys have no trouble melting the hearts of love struck bridesmaids.

Their perfect plan falters and all rules are broken when the boys crash the biggest wedding of the year and John falls for Claire Cleary (Rachel McAdams of Mean Girls), the engaged daughter of none other than eccentric politician William Cleary (Christopher Walken) the US Secretary of the Treasury! Meanwhile, Jeremy has his hands full with a man hungry female who wont take no for an answer (and who is frankly beginning to terrify him!)

With John intent on pursuing Claire and Jeremy being the pursued for a change, things get really wild when the guys spend a weekend at the palatial estate of the Cleary clan and find themselves way out of their depth.
