Audrey Kathleen Ruston Hepburn

She played Sister Luke in The Nun's Story (1959), which focuses on the character's struggle to succeed as a nun alongside co-star Peter Finch. The role accrued her third Academy Award nomination and earned her a second BAFTA Award. A review in Variety said "Hepburn has her most demanding film role, and she gives her finest performance." Films in Review stated that her performance "will forever silence those who have thought her less an actress than a symbol of the sophisticated child/woman. Her portrayal of Sister Luke is one of the great performances of the screen." Reportedly, she spent hours in convents and with members of the Church to bring truth to her portrayal: "I gave more time, energy and thought to this than to any of my previous screen performances."
Following this, she received lukewarm reception for starring with Anthony Perkins in the romantic adventure Green Mansions (1959) where she plays—"with grace and dignity"—the "ethereal" Rima, a jungle girl, who falls in love with a Venezuelan traveller played by Perkins, and The Unforgiven (1960), her only western film, where she appears "a bit too polished, too fragile and civilized among such tough and stubborn types" of Burt Lancaster and Lillian Gish in a story of racism against a group of Native Americans.
• Breakfast at Tiffany's and continued stardom
Three months after the birth of her son, Sean, in 1960, Hepburn began work on Blake Edwards' Breakfast at Tiffany's (1961), a film very loosely based on the Truman Capote novella. The film was drastically changed from the original version. Capote disapproved of many changes and proclaimed that Hepburn was "grossly miscast" as Holly Golightly, a quirky New York call girl, a role he had envisioned for Marilyn Monroe. Hepburn's portrayal of Golightly was adapted from the original: "I can't play a hooker," she admitted to Marty Jurow, co-producer of the film.
