Originally broadcast in 1990, Trials of Life is still one of the most comprehensive wildlife documentaries ever made. It examines animal behaviour in all its infinite variety and in doing so we are allowed to witness some of the most enchanting animal personalities, as well as some of the most fearsome. Leaving parents, searching for food, building a home, finding a mate; each day brings a new test, a challenge for even the fittest and best adapted animal. Taking some three and a half years to make, David Attenborough travelled almost a quarter of a million miles to complete this fascinating and insightful documentary.
