Three spectacular films revealing how documenting the natural world has changed during the 60 year career of one of the most important naturalists of the last century, Sir David Attenborough.

Sir David Attenborough has been at the forefront of natural history film-making for over half a century, witnessing an unparallelled period of change in our planet's history. In this unique and important series, he delivers his testimony in a trio of spectacular films, focusing on three areas which have transformed most profoundly over his career: film-making, science and the environment. During his extraordinary career he has seen, first-hand, more of the natural world than anyone else and witnessed how our remarkable planet has changed more rapidly and extensively than ever before.

In The Trials of Life: Capturing Behaviour, Attenborough turns to his long-running, landmark Life series to show how remarkable advancements in wildlife filming techniques have transformed our perception of the animal kingdom. Aerial filming revealed the unique hunt strategy of hunting dogs, sped-up time-lapse photography revealed that plants have a life and behaviour of their own, while endoscope lenses uncovered the secrets of an army ant nest – walls of interlocked, living ants. Leading developments in film-making, Attenborough's se­ries regularly revealed animal behaviours that had never been witnessed before.

Life on Earth –The Secrets of Evolution revisits sequences from his very earliest broadcasts to his most recent, illustrating how each breakthrough in biodiversity, genetics and evolutionary biology – his first passion, have transformed the way we understand the framework of the living world.

The final episode, The Living Planet: Our Fragile World, explores the threats now facing the natural world. Travelling back to the locations of his early series, Attenborough demonstrates the degree to which the wild world has shrunk in only a few decades. But he also reveals how much public attitudes, awareness and understanding of the natural world has changed over time.

Richly illustrated with the sequences he has spent 60 years capturing and packed with the personal anecdotes of television's most accomplished raconteur, this series is a unique synopsis of a unique half-century and a positive celebration of Attenborough's li­fe's work.
