This May, David Attenborough will celebrate his 85th birthday. And we’re doing a bit of early celebrating here, as we’ve finally sorted out the rights situation for his landmark first series, Life on Earth. As a result, you can expect to see this restored classic on DVD for the first time later this year. It is one of the longest Natural History Unit series BBC has ever made clocking in at thirteen hours, and its success launched his remarkable series of landmark “Life” programs—from Living Planet (1984) and Trials of Life (1990) to Life in Cold Blood (2008) and First Life (2010, which is also releasing later this year). Life on Earth looks at all of the earth’s surviving creatures through the prism of evolution, from invertebrates and first forests to primates and man. A critical and audience smash when it first aired in the UK, BBC eventually sold the show in 100 territories and it was seen by an estimated half a billion people. Interestingly, to make the series in 1979, BBC spent around a million pounds which wouldn’t pay for a single episode of one of our landmark series today.
