Cher... and Other Fantasies (1979)

After an opening number featuring women from history (all wearing Bob Mackie fashions), Cher finds herself lost in an abandoned building's atrium. With the help of a mystical sign painter (Elliott Gould) she visits several rooms in the building, where her alter ego encounters Shelley Winters selling tragic stories, a skate maker who lures her with magical red skates, and rooms where Cher performs various musical numbers. Lastly, she encounters a cleaning lady (Lucille Ball) who may be able to show her the way out - with the help of some magic from "Cinderella."
