David S. Goyer

Created the character Abraham Whistler for the film trilogy based on the Blade comic book. Ironically, the character ended up making his first appearance before the film came out, in an an episode of Spider-Man: The Animated Series (1994) in which Blade made a guest appearance. Whistler was voiced in that episode by Malcolm McDowell. Whistler subsequently was adopted into the continuity of the comic books.

We definitely set it up and kind of provided Warner Bros. a rough plan of what the next three movies would be. So it's not like we'll do one and then figure on the next. There is a road map of what the next three movies would be and who the various characters would be. [on Batman Begins (2005)]
