Filmmakers and the environment: David Attenborough

He probably wouldn't thank you for saying it, but Sir David Attenborough is the pin-up of the wildlife world. And, despite the fact that he turned 80 this year, Attenborough's enthusiasm for nature still captivates audiences around the world. Currently, Sir David is trekking the globe in search of reptiles and amphibians for his next great epic, Life in Cold Blood, due for delivery in 2008. But he has been a household name since 1979, when his breakthrough series Life on Earth attracted audiences of around 500 million.
