Film-maker Carol Morley created a sensational event with her latest film, Dreams Of A Life, a docu-dramatic study of Joyce Vincent, who became a tabloid story in 2006 when she was discovered to have lain dead in her North London flat for almost three years. The film touched on issues like social breakdown, sexual politics, and everyone's fear of loneliness but found something to celebrate in the happiness Joyce had brought to her friends. This film re-ignited interest in her earlier work, particularly The Alcohol Years, in which she turned the spotlight on herself. Now Morley joins Guardian critic Peter Bradshaw onstage to talk about her work. Is she an investigative-poetic realist?
