An amazing new nature film follows the epic journey of Emperor penguins across frozen landscapes as they migrate -- single-file -- to a familiar, yet mysterious destination. And at journey's end, life literally begins anew.Luc Jacquet, an ecologist-turned-filmmaker, directed March of the Penguins. He and a film crew spent 13 months in Antarctica filming the penguins' breeding cycle.Jacquet says he fell in love with the birds -- their robust white bellies, black coats, long beaks and the way they bob and sway as they walk -- on his first trip to Antarctica in 1992. With breathtaking photography, March of the Penguins illustrates just how far these animals walk to reach their destination -- a trip that takes about three months -- and to find a mate. Though the penguins make the remarkable journey year after year, scientists still aren't sure how they find their way.
