Shearer was nominated for an
Academy Award for Best Actress on six occasions, winning for her role in
The Divorcee in 1930. This was one of a series of roles Shearer played in sophisticated yet racy
pre-Code dramas. She was nominated the same year for her role in
Their Own Desire, in 1931 for her role in
A Free Soul, in 1934 for
The Barretts of Wimpole Street, in 1936 for
Romeo and Juliet, and in 1938 for
Marie Antoinette which was reportedly her favorite role.
Marion Davies later recalled that Shearer came to a party at
San Simeon in her costume, which required removing the door so she could enter, and four chairs so she could sit at the table.
Shearer was photographed with great care because she had a
lazy eye, however George Hurrell, who remained one of her favorite photographers, compensated by photographing her looking upwards. Her earlier successful roles were generally those of "modern" sexually uninhibited women. She was highly regarded for her performances that ranged from comedy to tragedy, but later in her career she preferred to play noble characters, and after Thalberg's death was well received in more unusual roles such as
Idiot's Delight (1939), her last of three films with
Clark Gable.
The Women followed and was a substantial success, but a group of younger actresses, along with Shearer's long time rival
Joan Crawford, received the best reviews. Shearer's marriage to Thalberg gave her a degree of power in Hollywood that was resented by rivals such as Crawford who complained that Shearer would always be offered the best roles and best conditions, with the comment, "...after all, she's sleeping with the boss." Shearer and Crawford acted only once together, as bitter rivals in
The Women. Critics praised the suspenseful atmosphere in Shearer's next film,
Escape (1940). The movie centered around a
Nazi general's lover who helps an American free his mother from a
concentration camp. With increasing interest of the
war in
Europe, the film performed well at the box office, but by this time Shearer had lost interest in her career.
