The basic joke of the film involves two buddies, John, played by Owen Wilson, and Jeremy, portrayed by Vince Vaughn, who crash weddings and carry out their discovery that weddings make women attending easy marks for seduction. A montage of the guys in action establishes the set-up. But the centerpiece becomes a high society family event in Washington ruled over by a government bigwig played amusingly by Christopher Walken as Treasury Secretary Cleary.

The plot is predictable in that we know the pals will meet their match, have the tables of love turned on them and eventually be exposed. Until the hearts and flowers take over, the exploits are quite funny. Wilson is handsome and endearing, especially when he is piling on the phoniness. Vaughn is the brash one, and although overbearing, can be very funny.

John is smitten by Cleary’s pretty daughter Claire (Rachel McAdams), but she intends to marry a stuffy suitor from another prominent family. Jeremy falls for Claire’s horny and daffy pint-sized sister Gloria (Isla Fisher). Jeremy thinks he has seduced a virgin, but Gloria turns out to be experienced and insatiable, whether tying him to a bedpost or masturbating him under the table at a family dinner. Jane Seymour plays Secretary Cleary’s sexually restless wife who surprises John by coming on to him. The film nicely twits the upper class, including focusing on a nasty foul-mouthed granny. But a gay misfit son is a distasteful caricature.
