Gary Oldman, the actor that plays Sirius Black, has been interviewed by
IGN Film Force. The interview is mainly about his role in the new up and coming movie role in Batman Begins but he spoke a bit about his role as the HP films.
Quote:
"Playing Sirius Black in last year's Harry Potter and the Prisoner of Azkaban and now Gordon in Batman, Oldman has to live up to the high expectations set for these popular characters. "I don't know. It depends. No one had been Sirius Black, so it was there for me to create it and hopefully make it how the original [book was]. [For Gordon], well he had to start somewhere. I'm not grey yet. Maybe the next one."
