Sarah Miles (born 31 December 1941) is an English theater and film actress. She was born in Ingatestone, Essex, England, as the daughter of a merchant. At the age of 15 she enrolled at RADA, the Royal Academy of Dramatic Arts.
Shortly after her drama studies, Miles had her film debut in 1962 as a precocious schoolgirl in Term of Trial (1962), opposite Laurence Olivier. The following years she became a popular actress of British New Wave with her roles in Joseph Losey's The Servant (1963) and in Michelangelo Antonioni's Blow Up (1966). After having been out of sight for several years acting in a variety of theater plays, she made in 1970 an outstanding performance in the lead role of David Lean's Ryan's Daughter, which earned her a nomination for the Academy Award for Best Actress.
Miles has been acting since then in movies and also in TV films. From time to time she retired for a few years, but was always available for roles on stage, where she is acclaimed for her performances.
Sarah Miles was twice married to the British playwright Robert Bolt, (1967-1975) and (1988-1995). He wrote the screenplay for the film Lady Caroline Lamb (1972), in which she starred.
