Wedding Crashers

Everything About Fiction You Never Wanted to Know.
The guys on the left and the right? They're not invited.

Bachelors and lifelong best friends, John Beckwith (Owen Wilson) and Jeremy Grey (Vince Vaughn) are partners at a law firm in Washington D.C. who frequently "crash" wedding parties to meet women; working from a set of rules taught to them by a past "crasher", the duo always have cover stories for inquisitive guests and inevitably become the hit of every reception -- all so they can charm their way into bed with ladies at the wedding for a one night stand.

After a sequence of successful "crashes," Jeremy spots the wedding of the daughter of the Secretary of the Treasury William Cleary (Christopher Walken) and his wife, Kathleen. After infiltrating the lavish event as brothers, John and Jeremy set their sights on two bridesmaids, also daughters of Secretary Cleary: Claire (Rachel McAdams) and Gloria Cleary (Isla Fisher). This 2005 film is the very definition of...you know.
