The Open Road

The Open Road is a 1926 British travel documentary film series narrating a journey by motorcar from Land's End to John O'Groats to explore life on 'the open road' across the United Kingdom. The Guardian has called it the "first comprehensive colour tourism film" of Britain. The film in part was designed to market the additive two-colour film process originally developed by Claude Friese-Greene's father William, and then improved by Claude as the "new all British Friese-Green natural colour process". The process renders colour by passing the light through a pair of red or blue-green filters, and then onto standard black-and-white film, alternating the filters every frame. When played back, the same alternating coloured filters are used to project in colour. It features various famous British locations: Land's End, Cornwall, St Michael's Mount, St Ives, Torquay, Glasgow, Stirling, Oban, Edinburgh and London. It was filmed between 1924 and 1926. Though it had some interest when previewed in 1925, it did not attain great success due to problems inherent to the colour processing, which produced colour fringing and flicker.
