Movie musical "The Wizard of Oz" is one of the most beloved films in cinema history. In 1939, MGM took L. Frank Baum's fantastic novel, "The Wonderful Wizard of Oz," and added catchy songs, great casting, elaborate makeup and special effects, and Technicolor. The resulting motion picture was at the time MGM's most expensive production; only upon subsequent releases did the studio recoup the investment. But the film became an enduring classic, with generations going "Over the Rainbow" and following the Yellow Brick Road with Dorothy and her friends. "There's no place like home," and there is no movie like "The Wizard of Oz."
