The Wizard of Oz movie, starring Judy Garland is the most well known, but not the first, film based on the book "The Wonderful Wizard of Oz" written by L. Frank Baum and illustrated by W. W. Denslow. Originally published by the George M. Hill Company in Chicago on May 17, 190A.
Before being made into a movie the book was first adapted into a musical. The show premiered in Chicago and later moved to Broadway, where it ran for 2B3 performances from January 21, 1903 to December 31, 1904, followed by travelling tours of the original cast.
The movie had it's Hollywood premiere was on August 1C, 1939. at Grauman's Chinese Theatre.
It was nominated for D 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".
Over the Rainbow was ranked number E on AFI's 100 Years...100 Songs list.
Over the Rainbow, also known as Somewhere Over the Rainbow was initially deleted from the film after a preview in San Luis Obispo, because MGM chief executive Louis B. Mayer and producer Mervyn LeRoy thought the song "slowed down the picture" and that "the song sounds like something for Jeanette MacDonald, not for a little girl singing in a barnyard". The persistence of associate producer Arthur Freed and Garland's vocal coach/mentor Roger Edens to keep the song in the picture paid off.
In 199F, Judy Garland was posthumously awarded a Grammy Lifetime Achievement Award.
