Even when the cameras aren't rolling, John Noble loves being Dr. Walter Bishop, the crazy, highly intelligent scientist from the hit Fox series "Fringe."

At San Diego Comic-Con in July, Noble couldn't stop talking about Season 2 of the series, which premieres Sept. 17 on Fox, and even shared the fact that when he was at Comic-Con, he had not even filmed a scene yet with Leonard Nimoy, the "Star Trek" legend who plays his scientific partner in crime, Dr. William Bell.

Noble has become an almost unexpected standout character on the show, despite being surrounded by younger people, going to show that age is not everything in television.

But don't expect Noble to take credit for Walter Bishop's or even "Fringe's" success. Instead, he gives that to the people who created the show: J.J. Abrams, Roberto Orci and Alex Kurtzman.

Now that's a classy guy!
