Andy Serkis: Getting under his characters' skin Pictures The face may not be familiar, but actor Andy Serkis has starred in some of this century's biggest films. In the "Lord of the Rings" trilogy, Serkis starred as Gollum, the schizophrenic creature who covets his "precious" ring, in a performance derived using motion capture technology that helped translate the actor's expressions and movements to computer animation. But motion capture, Serkis says, should not be considered merely a particular genre of acting. "It used to annoy me that people would say, "The voice of Gollum by Andy Serkis,'" he told CBS News' Anthony Mason. And it was like, 'Well, that's not true.' When an actor's playing a role using performance capture, they are authoring the role. Credit: New Line Cinema
