Griffin Keyes (Kevin James) is the perfect employee. In addition to being the favorite of all the animals at the Franklin Park Zoo, he's professional, courteous and well-liked by his co-workers. His dedication was only compounded when, five years earlier, he was dumped by his fiancée mid-proposal. But when his fiancée (Leslie Bibb) comes back into his life at his brother's engagement party, his career soon feels like an albatross around his neck.
Fearing the loss of their favorite zookeeper, the animals (voiced by Sylvester Stallone, Nick Nolte, Cher and others) intervene. They reveal the fact that they can speak and always could and then proceed to offer Griffin whatever help they can in winning back his former girlfriend. The attempts and advice vary in detail but what it all amounts to is a slapstick tsunami. It can enhance a storyline when used correctly but the use of it in this film is meant to replace one. It makes for a lot of laughs, but not a lot of originality. Basically, if you've seen the commercial, you've seen the movie. The kids will enjoy it, you might too, but you'd like it just as much if you waited to rent the DVD.
