The musical film is a touchstone for millions across the globe who have grown up under its spell. MGM’s 1939 classic The Wizard of Oz, filmed in the dawning days of Technicolor-and decades before CGI and high-tech special effects-is a hand-crafted cinematic achievement anchored by its extraordinary cast: Judy Garland as Dorothy, Ray Bolger as The Scarecrow, Jack Haley as The Tin Man, and Bert Lahr as The Cowardly Lion.
