Kevin James stars as Griffin, a sweet guy who works as head zookeeper at Boston's Franklin Park Zoo, a charming place with the city skyline in the background.
Stephanie (Leslie Bibb), the girl of his dreams dumped him five years ago because he had no ambitions beyond working at the zoo. He tends the animals at a job that he really likes, and has moved on. But when he sees her again at his brother's engagement party, he realizes he hasn't gotten over her and wants to try to win her back. He lacks the confidence to go after her, and mopes around the zoo complaining to the animals as he does his daily rounds.
The animals at Griffin's zoo turn out to be pretty special. Once the zoo closes for the evening, the monkey opens their enclosures and they gather for nightly chats. The talking animals decide to help out their human friend by giving him advice how to get his girl back.
Adam Sandler voices the monkey, Sly Stallone is the male lion, Cher voices the female lion and Nick Nolte gives his deep, emotional voice to a Gorilla, who Griffin has a special relationship with. At first he's astonished of their talents, but then he begins to take their advice as to how to strut and talk and have confidence. Although some of the animals are entertaining, there's a weird scene with a wolf marking his territory.
The star's voices are a good match to the animal's personalities, and the character's mouths are in perfect sync with the dialogue.
Rosario Dawson is good as Griffin's co-worker and cleans up really well when he takes her out to make Stephanie jealous.
Kevin James usually makes me laugh, and he has a couple of funny scenes here, but the script is confusing. Talking animals appeal to kids, but the storyline of trying to get back a lost romance won't. So, I'm not sure who the target audience is.
