George Stevens was born in Oakland, California, and his family included his father Landers Stevens and his mother Georgie Cooper, both stage actors. His uncle was drama critic Ashton Stevens. He also had two brothers, Jack and writer Aston Stevens. He learned about the stage from his parents and worked and toured with them on his path to filmmaking. He broke into the movie business as a cameraman, working on many Laurel and Hardy short films, such as Night Owls (1930). His first feature film was The Cohens and Kellys in Trouble in 1933. In 1934 he got his first directing job, the slapstick Kentucky Kernels. His big break came when he directed Katharine Hepburn in Alice Adams in 1935. He went on in the late 1930s to direct several Ginger Rogers and Fred Astaire movies, not only with the two actors together, but on their own. In 1940, he directed Carole Lombard in Vigil in the Night, and the film has an alternate ending for European audiences in recognition of World War II, which at the time the U.S. had not yet entered. During World War II, Stevens joined the U.S. Army Signal Corps and headed a film unit from 1943 to 1946, under General Eisenhower. His unit shot footage documenting D-Day—including the only Allied European Front color film of the war—the liberation of Paris and the meeting of American and Soviet forces at the Elbe River, as well as horrific scenes from the Duben labor camp and the Dachau concentration camp. Stevens also helped prepare the Duben and Dachau footage and other material for presentation during the Nuremberg Trials. In 2008, his footage was entered into the United States National Film Registry by the Library of Congress as an “essential visual record” of World War II.

One result of his World War II experiences was that his subsequent films became more dramatic. The motion picture I Remember Mama from 1948 was the last movie that he made with comic scenes. He was responsible for such classic films as A Place in the Sun, Shane, The Diary of Anne Frank, Giant and The Greatest Story Ever Told. He ended his directing career with the 1970 film The Only Game in Town with Warren Beatty and Elizabeth Taylor. In the same year, he was head of the jury at the 20th Berlin International Film Festival. In 1973 he was a member of the jury at the 8th Moscow International Film Festival. Stevens died following a heart attack on March 8, 1975 on his ranch in Lancaster, California, north of Los Angeles.
