In MGM's 1939 musical adaptation "The Wizard of Oz", Uncle Henry is played by Charley Grapewin. Hickory (Tin Man's alter ego) addresses Aunt Em as "Mrs. Gale" just before she offers crullers to the three farmhands, and Hunk (Scarecrow's alter ego) does so just afterward. The name "Gale" appears on the mailbox and Miss Almira Gulch (Wicked Witch's alter ego) addresses him as "Mr. Gale". (Baum, however, never gives Uncle Henry's surname in his books, nor indicates whether Henry or Em is Dorothy's blood relative. It is also possible that "Aunt" and "Uncle" are affectionate terms of a foster family and that Dorothy is not related to either of them.) In this film, Uncle Henry and Aunt Em are the only characters whose roles are limited to the Kansas sequence and do not make an appearance in the Oz sequence, although Aunt Em is seen again in the crystal ball at the Wicked Witch's castle still looking for Dorothy. He and Aunt Em reunite with their three farmworkers, and Professor Marvel (Wizard's alter ego) when Dorothy awakens from being unconscious.
