David Cronenberg: It was not really an issue at all, in terms of casting. On the other hand, what was interesting was while we were shooting the movie, all these "Cosmopolis" websites popped up that were created by "Twilight" fans and Rob fans, and they were reading the book and exchanging notes about the book and how it might work in the movie. Really, I wasn't thinking that this was necessarily going to be an audience for this movie, but then I started to think, "Well, some of them, it definitely is going to be." And that was exciting 'cause these are young girls who maybe had read "Twilight" and "Harry Potter," and suddenly they're reading Don DeLillo. That's pretty good.
