Denis Clifford Quilley, OBE (26 December 1927 – 5 October 2003) was an English actor and singer. From a family with no theatrical connections, Quilley was determined from an early age to become an actor. He was taken on by the Birmingham Repertory Theatre in his teens, and after a break for compulsory military service he began a West End career in 1950, succeeding Richard Burton in The Lady's Not For Burning.
