In August 1965, David Attenborough took viewers along the Zambezi river from its source in the centre of Africa to the Indian Ocean.

"There is a magic, a special logic, in a journey that follows a river", he wrote, in a Radio Times article introducing the series. "Your path is not something devised merely to suit your fancy. It is dictated by the shape of the hills, the slope of the plains, the history of half a million years. The sight and the sound of waters beside you provide a daily companionship. Soon you come to regard the river as a personality."

50 years later, you can still undertake this 2,000-mile journey and watch the series, which is part of BBC 4's Attenborough Collection of programmes, letters and photographs showcasing the early work of the wildlife presenter.
