Walking with Monsters is a three-part British documentary film series about life in the Paleozoic, bringing to life extinct arthropods, fish, amphibians, synapsids, and reptiles. As with previous Walking with... installments, it is narrated by Kenneth Branagh. Using state-of-the-art visual effects, this prequel to Walking with Dinosaurs shows an epic 300 million year war between creatures before the dinosaurs. The series draws on the knowledge of over 600 scientists and depicts Paleozoic history, from the Cambrian Period to the Early Triassic Period. It was written and directed by Tim Haines. As with some of the other BBC specials, it was renamed in North America, where its title was Before the Dinosaurs: Walking with Monsters. It has also aired as a two-hour special on the Canadian and American Discovery Channel with yet another narrator though Kenneth Brangh's narration can be heard in this version sometimes. At the 58th Primetime Emmy Awards in 2006 it won the Emmy Award in the category Outstanding Animated Program.
