UNIVERSAL CITY, California -- Arnold Schwarzenegger did it. Sylvester Stallone sort of did it. So can action star Vin Diesel do comedy?

Brittany Snow thinks so.

"Actually, he was really good," said the "American Dreams" actress, who co-stars with Diesel in the upcoming "The Pacifier." "He played exactly what you would think and he's really hilarious. I think a lot of people will like it because he's dealing out of his norm, he's dealing with babies and a hormonal teenager who tries to kick his butt. It's really funny."

In "The Pacifier," Diesel plays an undercover agent who, after failing to protect an important government scientist, attempts to redeem himself by watching over his family.

"He's our bodyguard and he has to protect us from these crazy people who are trying to kill us," Snow added. "I'm a rebellious teenage girl who wears a lot slutty outfits and really makes his life a living crazy world."

Adam Shankman, whose résumé includes "Bringing Down the House," "A Walk to Remember" and "The Wedding Planner," directed the movie, which Scott Alexander ("Agent Cody Banks," "Ed Wood") co-wrote. The film is slated for release next spring.

"The Pacifier" is Snow's first attempt at comedy, as well as her first movie made for the big screen. The actress has been in a few made-for-TV movies and spent three years on "The Guiding Light" but is best known as "American Bandstand" dancer Meg Pryor on "American Dreams."

Snow just started shooting the third season of the drama, which will find "Gilmore Girls" star Milo Ventimiglia joining the cast.

"[He's] my new love interest, which is great because I love him -- not in that way, but I think he's an amazing actor," Snow said. "We've already worked together a little bit and he's amazing and so much fun, so that'll be interesting. And Ben Taylor, the son of James Taylor, is actually going to be on our show for a while and he's been amazing. We're getting more controversial and a little more dramatic, so that's always good."

The season premiere, airing September 26, will feature Brandy as Gladys Knight, singing "I Heard It Through the Grapevine." The following week will see Nicole Richie as a member of the Exciters, singing "Tell Him."

"She's an amazing singer and has never gotten to be seen, I think it was her first performance, so we were really, really excited," Snow said. "She was really excited too. We always love it when the performers really enjoy being there."

Snow said the show is working on bringing Usher, Michelle Branch and Tyler Hilton back. "And I'm pulling for Ashlee Simpson to come, because I love her and I think she needs to be on the show," she said.

"American Dreams" shoots until May, after which Snow hopes to make another movie.
