The Wizard of Oz

The Wizard of Oz was a motion picture released in 1939, based on the novel The Wonderful Wizard of Oz by L. Frank Baum.

The Wizard of Oz was a favorite film of a member of USS Enterprise's psychiatric team, who conjured an image of the Scarecrow character as a companion during a visit to the Amusement Park planet. (TOS short story: "The Girl Who Controlled Gene Kelly's Feet")

This film was the original source of the song "If I Only Had a Brain," which Dr. Ira Graves taught to Data shortly before his death. (TNG episode: "The Schizoid Man")
