At least it isn't Will Ferrell, Adam Sandler, Rob Schneider, or Chris Rock.
Carrell certainly has the right look. I don't know what his voice sounds like. I understand he has good comedic skills. I've never seen him in anything.
Great choice! Carrell is hilarious. His anchorman in Bruce Almighty was hit-the-pause-button funny, yet he did it absolutely deadpan.
