Samuel Grosvenor Wood (July 10, 1883 – September 22, 1949) was an American film director and producer, who is best known for having directed such Hollywood hits as A Night at the Opera, A Day at the Races, Goodbye, Mr. Chips, and The Pride of the Yankees, and for his uncredited work directing parts of Gone with the Wind. He was also involved in a few acting and writing projects. As a youth Wood developed an enthusiasm for physical fitness that persisted into his senior years and influenced his interest in making sports-themed films.
