Edward Norton ready to run for a cause

Edward Norton is training with Massai Warriors.

Actor Edward Norton joined the show to discuss training for the New York City Marathon. He's running with Massai Warriors to raise awareness for the Massai Wilderness Conservation Trust.

Norton is using Twitter to promote his effort, which is unusual for him, because he's very private. He also said he was in a lot of pain training. He had bad shin splints. But he's gotten through that.

Norton is a big Baltimore Orioles fan. He was at Cal Ripken's rookie game and the game he broke Lou Gehrig's record.

Norton said he's never done a traditional sports movie (they don't count Rounders as a sports film). Norton is a huge fan of sports movies though. He loves Hoop Dreams, The Natural, Chariots of Fire and He's Got Game.

Norton did say he enjoyed working with Tony Siragusa on 25th Hour. Norton was very impressed with Siragusa's acting. Norton said often he looks at the director like "what did you do to me." But he didn't have to do that with Siragusa.
