According to a Paramount press release, on 28 March 1938, while waiting to be called to join Fred MacMurray and Harriet Nelson for a scene, eight-year-old actor Billy Lee had two of his teeth knocked loose by his young stand-in, Roland Smith, when the two boys simultaneously attempted to grab for a ball they were playing with - the top of Smith's head crashed into Billy's face. Director Alfred Santell had Billy whisked off to a Hollywood dentist's office in a studio car while scenes not needing Billy were filmed instead. After extracting the two drooping teeth, the dentist, Dr. Ervin Robert Barr, working from a studio still of Billy, created a removable plate for him, that was an exact match of his original teeth, by 7:00 that evening. Since Billy was needed for many scenes in the movie, Santell did not want to risk another change in his shooting schedule or a sudden, unexplained change in Billy's appearance, such as missing teeth. So Santell asked Billy to refrain from any rough-and-tumble activity and to stick to soft foods for the duration of filming, as Billy also had two loose baby teeth from before the mishap which Santell was determined would make it to the last scene.
