Wedding Crashers was the big winner at Saturday's 2006 MTV Movie Awards in California, collecting three prizes, including the coveted Golden Popcorn trophy for best movie.

The film also earned breakthrough performance honours for Isla Fisher and best on-screen team award for Vince Vaughn and Owen Wilson.

The unconventional awards show, held on a soundstage at Sony Studios, celebrates the fun of films with prizes recognising the best on-screen hero and villain, kiss and fight, and sexy, funny and frightened performances.

Show host Jessica Alba turned current blockbusters into comedic treats with parodies of The Da Vinci Code, Mission Impossible: III and King Kong.

"It was a lot of work" making the mini-movies, she said. "At the end of the day, I needed a bath and a cry."

Alba took home her own Golden Popcorn trophy for her sexy performance in "Sin City."

Jake Gyllenhaal was a double winner. He beat out Oscar-winner Reese Witherspoon for best performance and teamed with Brokeback Mountain co-star Heath Ledger for best kiss.

"This is a real honour, not just for me and Heath but for all of you, that you picked this movie and this kiss over all the other ones," Gyllenhaal said.

Awards are based on fan votes.

Rapper LL Cool J presented Spike Lee with the Silver Bucket of Excellence for Do the Right Thing, his 1989 film examining racial tensions. The prize honours a movie from the past that has present-day resonance.
