Most people know that the American sweetheart solidified her sex-symbol status with her femme fatale role in Niagara. In Gentlemen Prefer Blondes, with co-star Jane Russell, she flaunted her triple-threat versatility with an unforgettable performance of “Diamonds Are a Girl’s Best Friend.” And, with features like How to Marry a Millionaire, The Seven Year Itch, The Prince and The Showgirl, and Some Like It Hot, she popularized the “dumb blonde” stereotype—for better or for worse.
A speech therapist reportedly trained her to adopt the throaty style, and it ended up becoming one of her standout traits as an actress and singer. While Monroe was filming her final movie, Something’s Got to Give, her stutter returned, making it very difficult for the actress to deliver her lines. 20th Century Fox later fired her from the film.
2. Monroe was supposed to play Holly Golightly in 1961’s Breakfast at Tiffany’s.
“She was Truman Capote’s first choice,” Sam Wasson, author of Fifth Avenue, 5 A.M.: Audrey Hepburn, Breakfast at Tiffany’s, and the Dawn of the Modern Woman, told ABC News. “Another thing you may not know: Marilyn didn’t take the part in part because Paula Strasberg, her advisor and acting coach, said she should not be playing a lady of the evening.” Capote, author of the 1958 novella, was reportedly very disappointed that the studio went with Hepburn, saying, “Paramount double-crossed me in every way and cast Audrey.”
