In this wild and outrageous computer-animated comedy-adventure, an odd assortment of animals from the New York Zoo - including a lion, a giraffe, an anaconda, a koala, and a squirrel - discover what a jungle the city can be when one of their own is mistakenly shipped to the wild and they embark on a dangerous mission to rescue him. The film boasts an impressive vocal ensemble - Kiefer Sutherland (as the respected lion leader, Samson), Greg Cipes (as Samson's son, Ryan), Jim Belushi (as Benny, the street savvy squirrel and Samson's best friend), Janeane Garofalo (as a quick-witted giraffe), Richard Kind (as a dim-witted anaconda), William Shatner (as a wicked wildebeest), and Eddie Izzard (as Nigel, an acerbic koala) - along with cutting edge animation, and a story filled with hilarious situations.
