They develop, then cut an elaborate number involving Dorothy’s escape from the Witch’s castle over a rainbow bridge (a special effect used with great success in the stage production of The Tik-Tok Man of Oz, 1913).

Singer’s own touring company, the Singer Midgets, shares a rented house.In addition to those signed by Singer, MGM begins to hire little people who learn of the studio’s need by word-of-mouth and head for Hollywood, hoping to join the cast.Their costumes are individually designed by Adrian, and each person’s makeup is created by Jack Dawn. The makeup is applied using an assembly line with stops for facial appliances, rubber head pieces, cosmetics, and hairpieces.
