Not only do we end up with a vivid, surprising and soulful sense of one artist and his work, but Leigh also offers us a commanding view of a city, London, and country at the dawn of the modern age and of a man being overawed and overtaken by new technologies such as photography and the railways. As ever with Leigh, ‘Mr Turner’ addresses the big questions with small moments. It’s an extraordinary film, all at once strange, entertaining, thoughtful and exciting.
