Beverly Wills, who plays Joan Davis as a child, is really Joan Davis' daughter, according to the opening credits. Her singing sounds dubbed by her mother.
Joan Mason is seated in her dressing room, holding a cup and saucer. She tosses away the cup, which shatters on a door, but in the next shot it is back in the saucer.
Opening credits are shown on curtains pulled on stage by ladies, as the ladies walk across stage.
