Well, I think it's a weird choice actually. Ik think Carrey would be great as the mayor, especially cause I see Jim in the character. Moving with those arms and that face and doin' a hilarious voice. I think this Grinchy Who would fit him.
And I think Carell would be the perfect elephant when I think of his hilarious Hammy from 'Over the Hedge'.
Weird choice, but maybe the suprise is much bigger then. And I also want Ellen Degeneres in the cast! Up till today nobody beated her voice performance in 'Finding Nemo'. Exept for Robin Williams, that guy was brilliant as Genie in 'Aladdin'.
Nice elephant by the way.
