Hmm, Shirley Temple as Dorothy. Singing Sonewhere Over The Rainbow,,, At the time of casting it was always Shirley Temple they saw as Dorothy, in fact it was going to happen when big biz arguing changed the course and Judy Garland got the role. I can't think of anyone that could replace Garland in that movie. Ditto to the scarecrow, tin man and cowardly lyon. I don't know the details of this story. Maybe someone will chime in with the details?
