MTV recently visited the set of the upcoming New Line Cinema comedy, The Wedding Crashers, starring Vince Vaughn, Owen Wilson and Rachel McAdams. Here's a look...

"Vince and I play two guys who go to weddings to pick up girls, and it's the idea that girls might be sort of good to go at weddings," Wilson finally explains with the raise of an eyebrow. RELATED: Owen Wilson Confirms Wedding Crashers 2 Talks: I'm Sure We'll Do It

Specifically, Wilson and Vaughn are partners at a Washington, D.C., divorce mediation firm who have come to realize that women are aroused in a nuptial atmosphere. That the lifelong friends are never actually invited to the weddings they attend is hardly a setback. In fact, Wilson and Vaughn's characters have been crashing weddings for so long they have it down to a science.

"You pick a location [to sit for the ceremony] where you can see the bridesmaids enter, but not so close that you have to make eye contact with the wedding party," Vaughn explains, pointing to the spot where he and Wilson sat for the scene shot a few hours earlier. "It's all about positioning for all the things you're looking for. You gotta be able to see all the girls."

To add a little more fun to the experience, their characters also make games out of wedding crashing.

"Some of these services are kind of long, so we sort of make bets throughout the services, like what they're going to read from for the wedding, if the bride is going to cry or not, things to help us get through the service part of it," Wilson reveals.

Where the wedding crashers get thrown off in the movie is when they fall for bridesmaids of the daughter of the Secretary of Treasury, played by Christopher Walken. When Wilson and Vaughn's characters get invited to a weekend's worth of post-wedding festivities, the crashers meet their biggest challenge yet.

"One of the exciting things about this wedding that we're attending is that we're going to be shooting in Washington, D.C., at the National Cathedral, and we're going to have Senator John McCain and James Carville there," Wilson reveals.

The bridesmaids are played by Rachel McAdams of "The Notebook" and Isla Fisher of "I Heart Huckabees," two relative newcomers Wilson and Vaughn have enjoyed taking under their wings.

Two of comedy’s hottest stars - Vince Vaughn and Owen Wilson - team up for the first time in Wedding Crashers, a fast-paced comedy of love turned upside down. Vaughn and Wilson star as a pair of divorce mediators who spend their weekends crashing weddings in a search for Ms. Right…for a night. But when one of them falls for the engaged daughter (Rachel McAdams) of an influential and eccentric politician (Christopher Walken) at the social event of the year, they get roped into spending a wild weekend at the family’s palatial waterfront estate and quickly find themselves in over their heads. Wedding Crashers is directed by David Dobkin (Shanghai Knights).
