The Wizard of Oz is a 1939 American musical fantasy adventure film produced by Metro-Goldwyn-Mayer, and the most well-known and commercial adaptation based on the 1900 novel The Wonderful Wizard of Oz by L. Frank Baum. The film stars Judy Garland; Terry the dog, billed as Toto; Ray Bolger, Jack Haley, Bert Lahr, and Frank Morgan, with Billie Burke, Margaret Hamilton, Charley Grapewin, Clara Blandick, and the Singer Midgets as the Munchkins, with Pat Walshe as leader of the flying monkeys. Notable for its use of Technicolor, fantasy storytelling, musical score and unusual characters, over the years it has become one of the best known of all films and part of American popular culture. It also featured what may be the most elaborate use of character make-ups and special effects in a film up to that time.
Although the film received largely positive reviews, it was not a box office success on its initial release, earning only $3,017,000 on a $2,000,000 budget. The film was MGM's most expensive production up to that time, but its initial release failed to recoup the studio's investment. Subsequent re-releases made up for that, however. It was nominated for six Academy Awards, including Best Picture. It lost that award to Gone with the Wind, but won two others, including Best Original Song for "Over the Rainbow". The song was ranked first in the AFI's 100 Years...100 Songs list.
