The Technicolor film process was the dominant technology for shooting movies in color in Hollywood in the 1930s and '40s. It affected the way two film projects on the Land of Oz reached (or failed to reach) their audiences. On the negative side, animator Ted Esbaugh was unable to distribute his 1933 Oz cartoon because of a legal dispute with the Technicolor Motion Picture Corp., which kept a tight control on its processes. The Oz project presented some unique challenges: the Tin Woodman's shiny surface and the sparkling ruby slippers could cast reflections into the cameras that spoiled shots.
