Billy Crudup has starred in many films like Almost Famous, Big Fish and the upcoming Watchmen. However, you would most recognize his voice. As the voice of Mastercard, he names the priceless events that the credit card cannot buy.

As much as he loves Watchmen, he's not about to use his trademark line to shill the movie. "I don't think they have the money to pay me to declare this movie priceless," Crudup joked. "I'm not even sure if I'm allowed to say that word. I think I am."

The film is based on the landmark 1984 graphic novel by Alan Moore and Dave Gibbons. A group of superheroes deal with politics and metaphysics in an alternate history of the world.

Crudup plays Dr. Manhattan, an all powerful light form who won Vietnam for America, can see the future and teleport to Mars. Manhattan shares the spotlight with all the other Watchmen, but he can't help but stand out.

"Dr. Manhattan is definitely the bluest, and also the biggest and the nudist. Yes, he's the nudist."

Don't worry, Crudup kept his pants on on the set. He actually had to wear a full motion capture suit to create the CGI performance of Dr. Manhattan. Even his full frontal appearance was movie magic.

"I would have welcomed the experience. I like being nude in front of people as much as the next guy, but no, they insisted that I remain clothed and they do all the work on post production."

Watchmen opens March 6.
