"That 70s Show" goof Ashton Kutcher is about to grace the big screen in the teen comedy "Dude, Where's My Car?" but one of his TV co-stars has no interest in joining his friend in the teen film genre.

Topher Grace, who plays Eric on the Fox show, told TV Guide Online that he doesn't want to join Ashton in teen flicks.

"I'm kind of hard on teen movies," he said. "I don't like a lot of them, because [they're] from older executives guessing what their kids want to see. If my dad decided the kind of movie I'd want to see, I can guarantee you I wouldn't like it."

Topher is proving his opinion by appearing in the upcoming movie "Traffic", which stars Michael Douglas and Catherine Zeta-Jones as a drug addict. The film was just voted the best of the year by the influential New York Film Critics association.

The movie is about a judge who is given the task of taking on the U.S.'s war on drugs and then finds out that his young daughter is addicted to heroin. It is directed by Steven Soderbergh ("Erin Brokovich").

Topher told TV Guide that the thought of working with both Douglas and Soderbergh ,combined with his desire to play a character different from Eric, made the decision to take the role in "Traffic" an easy one.

"I remember saying to Steven that I wanted to do a one-eighty from what I am on TV," said Topher. "But the real reason I took the film is because of the company I'd be working with, not the role."

"Traffic" will open in wide release on Jan. 5.

Meanwhile, Ashton's movie will open this Friday (Dec. 15). It also stars "American Pie" and "Road Trip" actor Seann William Scott.
