The Letter (1940) was another Wyler coup, of which the critic Pauline Kael later wrote that Davis, who had earned her fourth Oscar nomination, gave "what is very likely the best study of female sexual hypocrisy in film history." Most of Davis's other films of the period were less than mediocre. Among her costars were Humphrey Bogart, Spencer Tracy, Paul Muni, James Cagney, Henry Fonda, Errol Flynn, George Brent, and Charles Boyer, yet she always resented that the studio system prevented her from acting with Clark Gable and Gary Cooper. On December 31, 1940 Davis married Arthur Austin Farnsworth, a hotel manager and an alcoholic, who died mysteriously in 1943. They had no children. During the 1940s, despite some of her strongest efforts, Davis grew less busy. In 1948 she earned $385,000 and was filmdom's best-paid star. One of her greatest roles was in Wyler's The Little Foxes (1941), made when she was on loan to MGM. In that movie, as the grasping Regina, she earned her fifth Oscar nomination despite a quarrel with Wyler, who refused to let her copy Tallulah Bankhead's stage interpretation. Other notable films include The Man Who Came to Dinner (1941), one of her few comedies; Now, Voyager (1942), a grand tearjerker in which she and costar Paul Henreid popularized the romantic practice of a man lighting two cigarettes and passing one to his lover (she was again nominated for an Oscar); Thank Your Lucky Stars (1943), in which she sang and danced; Watch on the Rhine (1943); Old Acquaintance (1943); Mr. Skeffington (1944), which costarred Claude Rains and gained Davis a seventh Oscar nomination; Hollywood Canteen (1944), a picture glorifying the eponymous United Service Organizations (USO) center she helped to found; and The Corn Is Green (1945). On 30 November 1945 she wed William Grant Sherry, an artist. They had one daughter. A Stolen Life (1946), her only film produced under the aegis of her own company, B.D., Inc., allowed her to play dual roles. In the same year she appeared in Deception with Rains and Henreid. Beyond the Forest (1949) was her last Warner Brothers film, notable mainly because of her often-quoted line "What a dump!" She divorced Sherry, a physically abusive alcoholic, in 1950. Her final film of the decade was the outstanding All About Eve (1950), in which she replaced Claudette Colbert, who was ailing, in the role of the aging Broadway star Margo Channing (a character portrayal based on the actress Elisabeth Bergner) and landed her eighth Oscar nomination for what many consider her finest role. This was the first of several films she made with her fourth spouse, Gary Merrill, whom she married that year. She and Merrill adopted two children, one of whom was retarded and eventually institutionalized.
