Julien Temple's remarkable, heartwarming, superbly edited documentary combines music, archive footage, clips from old feature films and new interviews to create a vivid portrait of a changing London. Its collage technique, humanism and sympathy for ordinary people has much in common with the vision of Britain created by Danny Boyle's team for the opening of the Olympics, both evoking the spirit of the great Humphrey Jennings. It ranges in time from the last days of Victorian England to the present. It's essentially a hopeful film about a vibrant city forever renewing itself. The imaginatively chosen music takes in the cockney knees-up of The Lambeth Walk, the Sex Pistols' Anarchy in the UK and the genteel romanticism of A Nightingale Sang in Berkeley Square.
