Me and Evan [Goldberg] talk a lot of shit. We have one rule when writing, and that's don't get attached to anything. One day we want to make a serious film and then Stephen Chow comes in with a good idea and we're like, 'Well it's funny.' Should we not do it because we originally wanted to do a serious film? We come from, nah fuck it, we'll just take the idea that seems good. So it's definitely less serious than a serious film, that's for sure. We want the action... I say now that we want the action to play serious but Stephen could come in tomorrow and say 'You know what? I want to throw you 400 feet in the air!' and I'd go, 'OK, that sounds cool.'

We're very open now. Right now is when we're in the process of deciding what this movie is going to be on a practical level. The story is the same; we've always known the story we wanted to tell, so it's easy within that to discuss the various sensibilities and reality levels and humor levels and stuff like that. To us, we hoped the director would come in and give us lots of ideas and directions to work with, and that's what he's doing.
