As the good doctor John Dolittle, who as we all know from the children's stories by Hugh Lofting can talk to the animals, Eddie Murphy finds himself upstaged by the animals. And voiced by a who's who of comics, these furballs, most notably Chris Rock as a trash-talkin' guinea pig, Albert Brooks as a suicidal tiger, and Norm MacDonald as Dolittle's sarcastic but big-hearted dog, are, as Jenna Elfman's owl might say, a hoot.
