VIDEO : What Does J.K. Simmons Do to Prepare for the Role of Commissioner Gordon

While praising actors who have previously played Gordon, and acknowledging that their portrayals have left him with an impression of the character even though Simmons himself is not a huge comic book fan, he told Collider that the biggest thing he's doing to prepare for his role -- which he plans to start shooting in a couple of months, due to scheduling -- is reading up on the source material. I?m still a couple of months out from doing that and I have two other films before then, so I haven?t gotten started on that," Simmons admitted.
