Motown Productions acquired the film rights to "The Wiz" in 1977 and signed Stephanie Mills in anticipation of having her star as Dorothy in the film adaptation. Motown singer and actress Diana Ross asked Motown CEO Berry Gordy to cast her instead, but he declined, feeling that the then-33-year-old Ross was far too old for the part. However, she contacted Rob Cohen of Universal Pictures, who offered to have them finance the film if she were to play Dorothy, at which point he acquiesced.
