Rhonda Fleming, the actress known as “the Queen of Technicolor” during Hollywood’s Golden Age and later made a mark as a philanthropist, has died. She was 97.

Fleming died Wednesday in a Santa Monica hospital, her assistant, Carla Sapon, told the New York Times.

As a teenager in the early 1940s, Fleming caught the eye of a talent scout for producer David O. Selznick, who cast her in Alfred Hitchcock’s 1945 film “Spellbound” and launched an international star.

Fleming deployed her talents in starring roles opposite Hollywood’s leading men, including Bing Crosby, Rock Hudson, Kirk Douglas, Charlton Heston, Burt Lancaster and Ronald Reagan. Producers quickly discovered the striking visual impact of her green eyes, auburn hair and creamy skin in Technicolor, which put Fleming in high demand for the westerns, period pieces and jungle adventure movies of the 1940s and ’50s.

Though Fleming never made, in her words, “a classic like ‘Casablanca,’ ” she proved herself a versatile actress. She stood out as the secretary who frames Robert Mitchum’s character in the celebrated 1947 film noir “Out of the Past” and as the villainous stepsister in the 1958 psychological drama “Home Before Dark.”

She could sing, too — and a lifelong ambition to do so blossomed in 1957, when she stepped onto the stage of the Tropicana nightclub in Las Vegas to rave reviews. She also appeared on Broadway, in a 1973 revival of Clare Booth Luce’s “The Women.”

Fleming was married six times. Her marriage to Ted Mann of Mann Theaters lasted 23 years, until his death in 2001.

Fleming was born Marilyn Louis on Aug. 10, 1923, in Hollywood. A flair for the stage ran in her veins — her mother, Effie Graham, was a well-known model and actress. But Fleming wanted to be a singer, like her idol, Canadian vocalist and actress Deanna Durbin.

“I never asked to be in motion pictures,” Fleming told the Las Vegas Review-Journal in 2009. “It just happened with the studio system. I wanted to sing. I studied to be a trained singer, and I worked at it and trained at it.”

Her fortunes took a fairy-tale turn toward film when a talent agent for Selznick spotted her outside Beverly Hills High School. Without even giving her a screen test, Selznick cast her as a violently seductive mental hospital patient in “Spellbound,” alongside Gregory Peck and Ingrid Bergman.

Beginning in the late 1970s, Fleming mostly retired from acting to work with various charities and to open the Rhonda Fleming Mann Resource Center for Women with Cancer at UCLA.

Married most recently to Darol Wayne Carlson, who died in 2017, Fleming is survived by her son, Kent Lane, and two granddaughters, five great-grandchildren and two great-great-grandchildren, Sapon told the New York Times.
