Lion: The Rise And Fall Of The Marsh Pride

This feature-length documentary focuses on the eponymous clan, whose activities have been charted by numerous camera crews from around the world for the past 40 years. Today their habitat on the Masai Mara in Kenya is gradually being whittled away, potentially thrusting them into a dangerous confrontation with their human neighbours. Archive footage is also used to reveal how life has changed for the lions over the decades. Tuesday, BBC2, 9pm
