Jennifer Ann Agutter OBE (born 20 December 1952) is a British actress. She began her career as a child actress in 1964, appearing in East of Sudan, Star!, and two adaptations of The Railway Children—the BBC's 1968 television serial and the 1970 film version. She also starred in the critically acclaimed film Walkabout and the TV film The Snow Goose (both 1971), for which she won an Emmy Award for Outstanding Supporting Actress in a Drama. She also played Sister Julienne in Call the Midwife.
Agutter was born in Taunton, Somerset, England. She is the daughter of Catherine (née Lynam) and Derek Brodie Agutter, a former British Army officer and entertainment organiser. As a child, she lived in Singapore, Dhekelia (Cyprus) and Kuala Lumpur (Malaya). She was discovered at Elmhurst Ballet School, a boarding school she attended aged 8–16, when a casting agent looked for a young English-speaking girl for a film. She did not get the part, but he recommended her to the producers of East of Sudan (1964).
