Alex the Lion (Ben Stiller) is the king of the urban jungle, the main attraction at New York's Central Park Zoo. He and his best friends Marty the Zebra (Chris Rock), Melman the Giraffe (David Schwimmer) and Gloria the Hippo (Jada Pinkett Smith) have lived their entire lives in blissful captivity, with regular meals provided and an admiring public to adore them.
