Q: First Pitch Black and this film defined certain worlds. What, beyond these worlds, could you do with the character, do you think?


A: Well, if we are fortunate enough to proceed from here, then I think logically we pursue-we do a lot of talk about the underverse in this movie, right? And this is for good reason. That would be a major venue in the next movie, should we get to do another movie, right And I'm quick to point out that the whole point of it was that this-the underverse is this collision of heaven and hell, this necromonger afterlife. If you can believe what they say-anybody who has adopted the faith will rise again in the underverse. So those are the things that we're exploring for the next movie, if we get the chance for it.
