In this video Waldemar Januszczak presents this battle between two of the early 20th Century's best-loved painter, Walter Sickert & John Singer Sargent. The film focuses on some of the most beautiful and alarming paintings ever made in the UK; evokes the long-lost atmosphere of Edwardian London; and above all, shows that these two immigrants were waging a war over nothing less than the future soul of British art.
