A product of London's Central School of Speech and Drama, Heather Sears made her stage debut in 1955's The Love Match. Two years later, Sears made her first London appearance as Alison Porter in John Osborne's Look Back in Anger. Her blossoming career received a booster shot when she was cast in the 1957 film melodrama The Story of Esther Costello, in which she played the title character, a psychosomatic deaf-mute. She was most active in films in the years 1960-62, appearing in Room at the Top (1960), Sons and Lovers (1960; as Miriam Leivers) and Phantom of the Opera (1962; as Christine). After her film career ended, Sears remained active in television (notably the 1975 version of Great Expectations) and on stage, working extensively with The Haymarket Theatre in Leicester. Heather Sears has also toured the English-speaking world in her one-woman show Viriginia Woolf.
