The Wild (2006)

Synopsis
A handful of zoo animals leave behind their well-protected environment for the streets of the big city in this computer-animated comedy. Sampson (voice of Kiefer Sutherland) is the king of a make-believe jungle far from the African plains -- he's a lion on display at a zoo in New York City's Central Park, and he lords it over the other animals, including Nigel (voice of Eddie Izzard), a testy koala bear; Larry, a dumb but well-meaning snake; ; Bridget (voice of Janeane Garofalo), a bright but cynical giraffe; and Benny (voice of Jim Belushi), a very New York-ish squirrel who is good friends with Sampson and is trying to romance Bridget without much success. The pride and joy of Sampson's life is his son, Ryan (voice of Greg Cipes), and he's devastated when one day Ryan is crated up and shipped back to Africa. Sampson is desperate to find his boy, and with the help of his pals he escapes the zoo and sets out on a daring mission to rescue Ryan, battling the unfamiliar terrain and Kazar, a wildebeest with a will to power and a passion for choreography (voice of William Shatner) along the way. The Wild was the first directorial credit for animator and special-effects artist Steve "Spaz" Williams. ~ Mark Deming, All Movie Guide
