In the summer of 1924 Claude Friese-Greene, a pioneer of colour cinematography, set out from Cornwall with the aim of recording life on the road between Land’s End and John O’Groats. Entitled The Open Road, his remarkable travelogue was conceived as a series of shorts, 26 episodes in all, to be shown weekly at the cinema. The result is a fascinating portrait of inter-war Britain, in which town and country, people and landscapes are captured as never before, in a truly unique and rich colour palette.
