In a forest near Leicester, a fossil discovery transforms understanding of evolution and the earliest forms of animal life.

Sir David Attenborough's journey continues in Canada's Rocky Mountains, where fossils document an unprecedented explosion in animal diversity, before travelling on to North Africa, the rainforests of Australia, and the east coast of Scotland.

Attenborough's Journey is a remarkable portrait of the man behind the legend. As he faces the challenges of a complicated shoot, discover a man in his element, immersed in his three great passions: fossils, the natural world and making films about them. Witness his infectious enthusiasm and unerring sense of humour as he reflects on a career that virtually spans the history of television itself.
