My Oscar Book:

She starred in Doctor Dolittle and in David Cronenberg’s horror masterpiece The Brood,

Her daughter, actress Jenna Stern, posted on Instagram, “My Mama passed Wednesday evening. Peacefully and quietly surrounded by family. I was there next to her …holding her hand, telling her how much she was loved. It was beautiful. It was a privilege.”

She struggled with “a long illness” before her death, her family told TMZ.

Nominated for 3 Oscars, including best director and adapted screenplay, William Wyler’s 1965 thriller The Collector, in which an odd fellow played by Terence Stamp holds Samantha Eggar’s character captive, gave boost to her career.

She starred with Cary Grant in his last picture, Columbia romantic comedy Walk Don’t Run, in which he plays matchmaker between a U.S. athlete (Jim Hutton) competing at the Tokyo Olympics and the young gal (Eggar) from whom he is renting a room.

The success of that film led to her casting in the high-budget “Doctor Dolittle,” starring as Emma Fairfax, love interest to the good doctor as played by Rex Harrison. (“Dolittle” was remade decades later with Eddie Murphy.)

In 1970 she also gavemstrong performance in the British film “The Walking Stick” as a woman who had polio as a child and has been left psychologically scarred.

She starred opposite Oliver Reed in Hollywood golden-age director Anatole Litvak’s last film, “The Lady in the Glasses With a Gun.”

With crisp English accent, she began doing voice work in the early ’90s, notably in Disney’s 1997 animated feature “Hercules,” in which she voiced queen of the gods Hera as part of a cast that also included Tate Donovan, James Woods; she reprised the role on the ABC series spun off from the movie.

She tried serial TV in 1972, starring opposite Yul Brynner in  CBS adaptation of Anna and the King whose run was brief.

After Bernard Girard’s horror film “A Name for Evil,” she focused on TV movies, a remake of “Double Indemnity” with her in the Stanwyck role.

She returned to the bigscreen as Dr. Watson’s wife in Herbert Ross’ Sherlock Holmes-meets-Sigmund Freud period adventure The Seven Per-Cent Solution, based on the novel by Nicholas Meyer.

Victoria Louise Samantha Marie Elizabeth Therese Eggar was born in Hampstead, London.

She began as an actress working with several Shakespearean companies.

Alexander Singer’s “Psyche 59,” a story of hysterical blindness starred Curd Jurgens, Patricia Neal and Eggar as the hub of the sexual-tension wheel.

In addition to “The Collector,” Eggar made in 1965: J. Lee Thompson’s noir melodrama “Return From the Ashes,” in which she played the lover of a chess-playing rogue portrayed by Maximilian Schell and the daughter of a female doctor (Ingrid Thulin) who survived the Nazi camps.

Eggar was married to actor Tom Stern from 1964-71.

She is survived by a daughter, actress Jenna Stern, and a son, film producer Nicolas Stern.
