The Lost World of Friese-Greene is a BBC documentary series produced in conjunction with the British Film Institute. Three one-hour episodes were broadcast on BBC Two in spring 2006. The series, presented by Dan Cruickshank, retraces a road trip that Claude Friese-Greene took between 1924 and 1926 from Land's End to John o' Groats. It also showcases The Open Road, a 26-reel film made by Friese-Greene along the way. The Open Road was filmed using the Biocolour process originally invented by his father William Friese-Greene, the moving picture pioneer, later developed further by Claude after his father's death.
