Chris Weitz, producer of American Pie and brother of

Pie director Paul Weitz, thought the most difficult part of making his acting debut in the new indie Chuck & Buck was going to be puckering up to another man. But that was before he realized he'd also have to sleep with a woman.

"I had never kissed a guy in real life, and I was nervous about what my friends and parents would think," Chris tells TV Guide Online. "Ironically, the most difficult scene for me ended up being my love scene with Beth Colt, who played my fiancée. She's married and has a small child and because that actually involved issues of morality, kissing a married woman was more difficult for me than kissing a guy."

Chuck & Buck, which opened in select cities on Friday, also stars Chris's frequent film partner Paul (the duo wrote the upcoming Nutty Professor sequel, The Klumps, and also recently directed Chris Rock in Down to Earth), although this may be their last on-screen collaboration. "We've had a couple of scripts sent to us to act in," Paul says. "I think it would be neat to do indie stuff acting-wise. Chris was more bored by the experience than I was. I was fascinated by it."

For now however, the super-successful siblings will go back to work behind-the-scenes, beginning with a sequel to Pie. Although they won't reveal any plot details of the follow-up, Chris does admit that there will be less toilet humor this time around. "I can't bear to watch the bathroom scenes [in the first one]," he says. "It's the most softball humor of the entire thing."

And there's even more bad news: Pie deux likely will include less gratuitous nudity. "It's one of the sacred cows of the teen films," adds the auteur. "It's almost a requirement we had to satisfy. I'd rather that we found other ways to do that. That's the one part of the movie that feels exploitative."
