Sally Thomsett Biography: Age, Height, Marriages, and More

Few actresses from the 1970s British screen have managed to stay as private as Sally Thomsett, the woman who played the wide-eyed Phyllis in The Railway Children at age 20 while convincing audiences she was 11. Born on 3 April 1950 in Sussex, she later became a household name as Jo in the sitcom Man About the House before stepping away from the spotlight entirely.

Nine key facts about Sally Thomsett, one pattern: her public career was brief but memorable, while her private life has remained largely out of view.

The implication: the public record is thin beyond her filmography — much of her personal life is only sketchily documented.

How old is Sally Thomsett and how tall is she?

What is Sally Thomsett’s birth date?

Sally Thomsett was born on 3 April 1950 in Sussex, England, according to Wikipedia. Her birth date is also confirmed by Rotten Tomatoes and IMDb. As of 2025, she is 75 years old.

How tall is Sally Thomsett in feet and centimeters?

Height records vary slightly. IMDb lists her as 5 feet 3 inches (1.60 m), while a lower-tier entertainment profile quotes 5 feet 2 inches. The most commonly cited figure in fan databases is 5 ft 2 in (1.57 m), which is used in this article.

The catch: without a primary source such as a passport or driver’s license, the exact height remains an estimate.

How many times was Sally Thomsett married and who was her first husband?

Who was Sally Thomsett’s first husband?

According to Wikipedia, Thomsett married Nigel Newman in 1971; they separated later that year and divorced in 1976. IMDb confirms the marriage lasted only from 1971 to 1971. Nigel Newman is not a public figure, and his background is not well documented in reliable sources.

Did she have children from her marriages?

Thomsett has one daughter, born in 1996, from her long-term partnership with Paul Agnew — not from either marriage. The 2019 Mirror profile identified the daughter as Charlotte. Her second marriage was to Danish film producer Claus Hede Nielsen in 1980; they separated in 1985. She has been with Paul Agnew since 1993, according to Wikipedia.

What this means: Thomsett’s family life has been stable and private — she has not remarried after her second divorce, and her partner Agnew is not a public figure.

How old was Sally Thomsett when she was in The Railway Children?

What year was The Railway Children released?

The film was released in 1970. Filming took place in 1969–1970, when Thomsett was 19–20 years old.

What role did Sally Thomsett play in the film?

She played Phyllis, the middle child of the Waterbury family. In a 2020 interview with the Mirror, Thomsett revealed she had to hide her breasts and wear a wig to appear 11 years old. The casting directors deliberately chose a young-looking adult to avoid child labour laws.

The implication: her performance as a child was a clever piece of theatrical deception that made the film work.

Did Richard O’Sullivan date Sally Thomsett, and did Paula Wilcox and Richard O’Sullivan have a relationship?

Were Sally Thomsett and Richard O’Sullivan in a real-life relationship?

No credible evidence suggests they dated. They co-starred in Man About the House (1973–1976) but were not romantically linked in any reliable source. Wikipedia makes no mention of such a relationship. The rumour likely stems from their on-screen chemistry.

What was the nature of Richard O’Sullivan and Paula Wilcox’s relationship?

Similarly, no confirmation exists of a romantic relationship between O’Sullivan and Wilcox, who co-starred in Man About the House and later in Me and My Girl. They were professional colleagues only.

The pattern: audiences often conflate fictional chemistry with real life, but in this case, the available records show no romance.

What has Sally Thomsett been in?

What is Sally Thomsett most famous for?

She is best known for two roles: Phyllis in The Railway Children (1970) and Jo in the ITV sitcom Man About the House (1973–1976). Both are iconic in British popular culture.

Did she appear in any horror films?

Yes — she appeared in Sam Peckinpah’s Straw Dogs (1971), a controversial thriller that gained notoriety for its violence. She played a minor role.

When did she stop acting?

Her career wound down in the late 1970s; she retired after a few TV roles in the 1980s. Her last credited work appears to be in the early 1980s, after which she left the industry entirely.

The trade-off: Thomsett’s fame peaked in a five-year window, but she chose to step away when the offers dried up — a decision that preserved her privacy.

Quotes

“I had to hide my breasts and wear a wig. I was a 20-year-old pretending to be 11.”

The mystery of Thomsett’s private life only enhances the charm of the characters she played.
