Tim Haines: Surviving Earth

Walking With Dinosaurs creator Tim Haines talks to Julian Newby about his new series Surviving Earth. He explains how technology has moved on since his epic Dinosaurs series, enabling him and his crew to film creatures that existed thousands or millions of years ago, in real-life locations around the world. With over 20 scientists working on each episode, the series visits parts of the world where plants and physical formation are close to those that existed thousands and even millions of years ago.
