Every Sunday

This film was not (as is often reported) a "screen test" of sorts produced by MGM to help the studio decide which of these two girls, Deanna Durbin or Judy Garland, to keep under contract. Durbin was released by MGM and signed by Universal prior to this movie's production. A blurb on 1 June 1936 in "The Hollywood Reporter" stated "Universal had changed Canadian-born Edna Mae Durbin's name to 'Dianna' [sic]." This movie, it appears, was not produced until at least July 1936, by which time Durbin had already been signed by Universal and cast in her debut vehicle, Tres diablillos (1936). The reason she appeared in this film was reportedly due to a provision in her MGM contract which entitled the studio to request her services for up to 60 days following its termination, provided she was not already shooting a film at her new studio. As filming on "Three Smart Girls" was not scheduled to begin until September 1936, Durbin found herself back at MGM making this short with Garland. This is why, although her on-screen character is called "Edna" in the short (Deanna's real name), in the credits she is billed under the name by which she would soon become internationally famous, "Deanna".

When the girls are singing, their mouths do not always match the soundtrack.
