Alex the Lion Alex is perhaps the first animated metrosexual lion. Voiced by Ben Stiller in the popular 2005 animated hit "Madagascar," Alex is the king, not of the jungle, but of the Central Park Zoo. Not only does Alex have a steak every day, he performs New York, New York for the throngs of visitors. But his perfect life abruptly ends when his best buddy, Marty the Zebra (Chris Rock), decides to escape from the zoo and check out New York. Alex, Melman the Giraffe (David Schwimmer) and Gloria the Hippo (Jada Pinkett Smith) set out after Marty only to end up captured, crated and shipped to a wildlife refuge in Africa. But they end up shipwrecked in the wilds of Madagascar after the penguins on the ship stage a mutiny. Soon Alex starts feeling his inner-lion and begins to think that Marty looks just as good to eat as his steaks. Alex and his gang will be back in a new adventure: Madagascar: Escape 2 Africa, which opens in November.
