Wedding Crashers (2005)

Jeremy and John are lifelong friends and spend their free time crashing different weddings, using a set of rules that they always repeat. They take advantage of the free booze and sleep with different women they don't know. When the wedding of Treasury Secretary William Cleary's daughter gets all the attention and John falls in love with her, the wedding crashers are put to the test. An irreverent comedy full of funny moments and a cast led by Owen Wilson and Vince Vaughn, who form a perfect duo.
