The turbulent personal and professional life of actor Peter Sellers (1925-1980), from his beginnings as a comic performer on BBC Radio to his huge success as one of the greatest film comedians of all time; an obsessive artist so dedicated to his work that neglected his loved ones and sacrificed part of his own personality to convincingly create that of his many memorable characters.
