Audrey Kathleen Ruston Hepburn

Having become one of Hollywood's most popular box-office attractions, she went on to star in a series of successful films during the remainder of the decade, including her BAFTA- and Golden Globe-nominated role as Natasha Rostova in War and Peace (1956), an adaptation of the Tolstoy novel set during the Napoleonic wars with Henry Fonda and husband Mel Ferrer. In 1957, she exhibited her dancing abilities in her debut musical film Funny Face (1957) where Fred Astaire, a fashion photographer, discovers a beatnik bookstore clerk (Hepburn), who, lured by a free trip to Paris, becomes a beautiful model. The same year Hepburn starred in another romantic comedy, Love in the Afternoon, alongside Gary Cooper and Maurice Chevalier.
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.
