Owen Wilson and Vince Vaughn are hilarious as smooth talkers John and Jeremy, who show up to weddings uninvited in order to lure single─and sometimes not-so-single─girls into one-night stands. But the pair's well-honed act hits a snag when they attend the nuptials of the treasury secretary's (Christopher Walken) daughter and John actually begins to fall for the sister-of-the-bride (Rachel McAdams). With Jane Seymour, Isla Fisher, and an uncredited Will Ferrell. 119 min. Widescreen; Soundtrack: English.
