I would, but not right away. It's definitely too much to do every time out, that's for sure. There's just so much to do that it's kind of hard to get any perspective on the movie. But the script I wrote with [''Permanent Midnight'' author and ''C.S.I.'' writer] Jerry Stahl, ''What Makes Sammy Run?'' [based on the Budd Schulberg novel], I'd like to act in that and I definitely want to direct it.

Derek Zoolander started as a sketch on the VH1 Fashion Awards. How do you avoid making another sketch-gone-bad movie like ''It's Pat''?

When a sketch-based movie works, it works really well, and when it doesn't, it really, really doesn't. What I learned in making the movie was that the same rules apply for all movies. No matter how silly or unrealistic the tone of the movie is, audiences want to connect with characters. With the main characters, Derek and Hansel, there's a real story between the two, a real relationship, and I was surprised to realize that's really where the movie does the best, when the two of them are together.
