Patton Oswalt is an American stand-up comedian, actor, writer and huge comic-book nerd. His most notable roles include recurring spots on "King of Queens" and as the voice of Remy the rat in Pixar's Ratatouille, and getting to roast William Shatner.
Patton was one of several writers brought in to "punch up" the script for the live-action movie, tweaking the script for more humor before filming began. He was also offered the role of Glen Whitmann, but had already committed to another film. [1]
