British actor David Langton is perhaps best remembered for playing Lord Bellamy on the long-running, British television series Upstairs, Downstairs (1971-1976). The distinguished leading and supporting actor appeared in numerous films and frequently guest starred on television shows such as The Avengers. Born Basil Muir Langton-Dodds in Motherwell, Scotland, he started out on stage in the early '30s. By the end of WWII, Langton began winning leading roles. In 1955, he began a sporadic film career, with The Ship That Died of Shame. His subsequent film credits include Saint Joan (1957), the Beatles' A Hard Day's Night (1964), and The Liquidator (1966). In addition to appearing in television series, Langton also worked occasionally in made-for-TV films, such as Winston Churchill -- The Wilderness Years and Charles and Diana: A Royal Love Story (1982). ~ Sandra Brennan, All Movie Guide
