Kenneth Griffith, actor and director, has never been far from controversy. His memoirs chronicle a childhood in Wales, war service and an acting career that began with Tyrone Guthrie at the Old Vic and has survived a close friendship with Peter O'Toole. It is as an idiosyncratic director of documentary-dramas that Kenneth Griffith has attained notoriety - the BBC banned two of his films about Ireland in the early 1970s and is now considering whether to broadcast them at last.
