The Daily Record calls this documentary, narrated by Bernard Hill, a "Don't Miss".

The Natural World is coming up for its 25th birthday but Titus, above, has been around a good deal longer, and at 33 years of age he is still king of the jungle in his mountain retreat in Rwanda.

It's rare for any wild animal's life to be chronicled over decades but Titus and his forbears were among the gorillas first studied in the wild by pioneering wildlife researcher Dian Fossey, of Gorillas in the Mist fame, and his whole life has been conducted in front of cameras.
