Maple Youth Ballet gets visit from original member of 1939 ‘Wizard of Oz’ movie cast at rehearsal Members of the Maple Youth Ballet had a special guest attend their rehearsal on Sunday. Priscilla Montgomery Clark, a member of the cast of the original 1939 film, shared stories with the cast about her time as a child actor, according to Maple Youth Ballet Executive Director Kathy Krade. Clark, who lives in Orange County, was 9 when she acted in the movie as a Munchkin. She told members of the cast that while she was not nervous to be on the film set, she was frightened by the Wicked Witch of the West – until she got to know her, that is. “Out of character, she was just the nicest person,” Clark recalled Sunday.
