After Roman Holiday she filmed Sabrina with Humphrey Bogart and William Holden, with whom she had a romance. Hepburn hoped to marry him and have children. She broke off the relationship when Holden revealed that he had a vasectomy.In 1954, Audrey went back to the stage playing the water sprite in Ondine in a performance with Mel Ferrer, whom she would wed later that year. For her performance in Ondine, Hepburn was awarded the Tony Award for Best Actress (1954) which, coming only six weeks after her academy award for Roman Holiday, solidified her reputation as both a film and stage star. By the mid 1950s Hepburn also came to be regarded as a major style icon, her gamine appearance and widely recognised sense of chic being both admired and imitated.Having become one of Hollywood's most popular box-office attractions, Audrey Hepburn co-starred with other major actors such as Fred Astaire in Funny Face, Humphrey Bogart and Gary Cooper in Love in the Afternoon, George Peppard in Breakfast at Tiffany's, Cary Grant in the critically acclaimed hit Charade, Rex Harrison in My Fair Lady, Peter O'Toole in How to Steal a Million, and Sean Connery in Robin and Marian. Many of these leading men became very close to her. Rex Harrison called Audrey his favorite leading lady; Cary Grant loved to humor her and once said, "all I want for Christmas is to make another movie with Audrey Hepburn;" and Gregory Peck became a lifelong friend. After her death, Peck went on camera and tearfully recited her favorite poem, "Unending Love." Some believe Bogart and Hepburn did not get along, but this is untrue. Bogart got along better with Hepburn than anyone else on set. Hepburn later said, "Sometimes it's the so-called 'tough guys' that are the most tender hearted, as Bogey was with me."Hepburn's performance as "Holly Golightly" in 1961's Breakfast at Tiffany's resulted in one of the most iconic characters in 20th Century American cinema. Hepburn called the role, "the jazziest of my career." Asked about the acting challenge of the role, Hepburn said, "I'm an introvert. Playing the extroverted girl was the hardest thing I ever did." She wore trendy clothing designed by her and Givenchy and added blonde streaks to her brown hair, a look that she would keep off-screen as well.Hepburn starred in 1964's My Fair Lady which was said to be the most anticipated movie since Gone With The Wind. Hepburn was cast as Eliza Doolittle instead of then-unknown Julie Andrews, who had originated the role on Broadway. The decision not to cast Andrews was made before Hepburn was cast for the role. Hepburn initially refused the role and asked Jack Warner to give it to Andrews, but when they informed her that it would either be her or Elizabeth Taylor, who was vying for the role, she decided to take the part. According to an article in Soundstage magazine, "everyone agreed that if Julie Andrews was not to be in the film, Audrey Hepburn was the perfect choice." Julie Andrews had yet to make Mary Poppins, which was released within the same year as My Fair Lady. Audrey recorded singing vocals for the role, but subsequently discovered a professional "singing double" Marni Nixon had overdubbed all of her songs. She is said to have walked off the set after being told of the dubbing and to have returned the next day apologizing for her behavior. Footage of several songs with Hepburn's original vocals still exist and have been included in documentaries and the DVD release of the film, though to date, only Nixon's renditions have been released on LP and CD. Some of her original vocals remained in the film, such as "Just You Wait" and snippets from "I Could Have Danced All Night". When asked about the dubbing of an actress with such distinctive vocal tones, Hepburn frowned and said, "you could tell, couldn't you? And there was Rex, recording all his songs as he acted...next time-" She then bit her lip to keep from saying any more. Aside from the dubbing, many critics agreed that Hepburn's performance was excellent. Gene Ringgold said, "Audrey Hepburn is magnificent. She is Eliza for the ages."The controversy over Hepburn's casting reached its height at the 1964-65 Academy Awards season, when Hepburn was not nominated for best actress while Andrews was nominated for Mary Poppins. The media tried to play up the rivalry between the two actresses as the ceremony approached, even though both women denied such bad feelings existed and got along well. Julie Andrews won "Best Actress" at the ceremony.From 1967 onward, after fifteen highly successful years in film, Hepburn acted only occasionally. After her divorce from first husband Mel Ferrer, she remarried Italian psychiatrist Dr. Andrea Dotti and had a second son, after a difficult pregnancy that required near-total bed rest. After her eventual separation from Dotti, she attempted a comeback, co-starring with Sean Connery in the period piece Robin and Marian in 1976, which was moderately successful, but not up to the usual standards of a Hepburn hit film. Surprisingly, she turned down the seemingly made-to-order role of a former ballet dancer in The Turning Point. (Shirley MacLaine got the part, and the successful film invigorated her career.) She later said that turning down the part was the biggest regret of her career. Hepburn made another comeback try in 1979, starring in Sidney Sheldon's Bloodline: Pulp author Sheldon's books were so popular his name was included in the film's title, no doubt leading Hepburn to think she had picked a winner. She hadn't. Among the reviewers, even Hepburn's admirers-- and there were still many-- could not recommend the film due to its hackneyed material.Hepburn's last starring role in a film was with her new flame Ben Gazzara in the modern comedy They All Laughed, a small, hip and breezy picture-- a real departure for Hepburn-- directed by Peter Bogdanovich. A critical success, the film was overshadowed by the brutal murder of one of its stars, Bogdanovich's girlfriend, Dorothy Stratten; the film was released after Stratten's murder at age 20 and was not a major hit. In 1987, she co-starred with Robert Wagner in a tongue-in-cheek made-for-television caper film, Love Among Thieves which borrowed elements from several of Hepburn's films, most notably Charade and How to Steal a Million. The TV-film was only a moderate success, with Hepburn being quoted that she appeared in it just for fun.Hepburn's last film role, a cameo appearance, was of an angel in Steven Spielberg's Always, filmed in 1988. A rare Spielberg fizzle, few got to enjoy Hepburn looking, indeed, angelic, before the film was pulled from theaters.
