I always think part of success is being able to replicate results, taking what is interesting or viable about yourself as a professional person and seeing if you bring it into different situations with similar results.

But I think Kiss Kiss, Bang Bang really got that thing where, if a movie reads really funny and then has some dramatic or violent or sinister stuff in it, you can't forget that primarily it has to be even funnier than you read it or that other stuff doesn't work.

I read the script for Wonder Boys, and I said that was almost perfect, it was so classy, cool and funny. It's a really specific thing. We stuck to it, it turned out good and a lot of people liked it.
