Before the babbling minions of Universal's "Despicable Me" movies became so popular, there were the wisecracking penguins of DreamWorks Animation's "Madagascar" films. The first, in 2005, introduced the penguins as four bumblers who believe they comprise a military task force. It seemed like a limited joke, but in 2008, Nickelodeon gave the penguins their own series, and now DreamWorks is giving them their first feature.
