“The Hart of London” is an endlessly layered tour de force. It explores life and death, the sense of place and personal displacement, and the intricate aesthetics of representation. It is a personal and spiritual film, marked inevitably by Chambers’s knowledge that he had leukemia. The late American avant-garde filmmaker Stan Brakhage said of Hart, “If I named the five greatest films [ever made], this has got to be one of them.” Even this high praise falls short of hyperbole. The Hart of London is at the centre of Chambers’s extraordinary achievement.
