This cute 'n' cozy comedy is based on Alan Bennett's 1989 play--which was, in turn, based on something that actually happened to him. For 15 years a cranky homeless woman lived in a van in Bennett's driveway. Here, Dame Maggie Smith stars as the titular "lady," Miss Shepherd. Alex Jennings (The Queen, Babel) plays Bennett, the flummoxed intellectual who develops a strange kinship with his course, opinionated semi-houseguest. The film was shot in the actual house in Camden Town where it took place, giving it a distinctly British veracity. 104 minutes PG-13.
