"Just as the goat that symbolizes Capricorn is a natural climber, both comedians began their careers in comedy clubs where they honed their craft and climbed to the top of a very competitive profession. Capricorns demand excellence from themselves, and these two performers are no exception. Both are noted for their impeccable impersonations: Kaufman of fellow Capricorn Elvis Presley, and Carrey of Jimmy Stewart and Gandhi."

I agree that Carey was perfect for the role. It was by far his best performance as an actor. But Ed Norton might have been an interesting choice.
