Major Clark Gable (February 1, 1901 – November 16, 1960) was an iconic American film actor who lived during the 20th century. Gable was known to have been in a total of eighty theatrically released motion pictures.
In 1930, Edith Keeler invited James T. Kirk to watch a Clark Gable film with her at the Orpheum. This film was most likely Du Barry, Woman of Passion. Neither Kirk nor Doctor Leonard McCoy had ever heard of Gable. (TOS episode & novelization: The City on the Edge of Forever)
His best known film was Gone with the Wind, which was released in 1939. In that year, Benny Russell saw the film as part of a double bill with a Flash Gordon chapter. (DS9 novelization: Far Beyond the Stars)
In an alternate timeline in which the USS Voyager suffered near constant attacks by the Krenim over more than a year, B'Elanna Torres incorrectly guessed that Gable had starred in the 1955 film To Catch a Thief, which she had seen twice, when it was in fact Cary Grant. Harry Kim believed that she was mixing them up because they had the same initials. (VOY episode: "Year of Hell")
