9The Marsh Lions tells the story of a pride of lions in Kenya's world-famous Masai Mara game reserve. For five years, Brian Jackman and Jonathan Scott followed the Marsh pride and their progeny, recording the daily drama of life and death on the African plains. In time they came to regard them as old and familiar friends and real individuals. The Marsh Lions were the most successful group to be filmed for Big Cat Diary, the BBC's hugely successful TV series presented by Jonathan Scott.
