Wizard of Oz is a 1925 American silent film directed by Larry Semon, who also appears in a lead role"?that of a farmhand disguised as a Scarecrow. The only completed 1920s adaptation of L. Frank Baum's novel The Wonderful Wizard of Oz, this film features a young Oliver Hardy as the Tin Woodman. "L. Frank Baum, Jr." is top-billed with the writing of the script. This is Frank Joslyn Baum, Baum's eldest son, and although his actual contribution to the screenplay is doubted by Baum scholar Michael Patrick Hearn, he was certainly involved in the business angle of the production.
