Little Nellie Kelly is a 1940 American musical-comedy film based on the stage musical of the same title by George M. Cohan which was a hit on Broadway in 1922 and 1923.

Years later, Jerry is now a captain on the police force, and Nellie (also played by Judy Garland) has grown up as the spitting image of her mother.

Michael dotes on his granddaughter but is embarrassed when she sings in public at the police department parade (It's a Great Day for the Irish).

Jerry is happy for her, but Michael objects to the romance, and when Nellie, encouraged by her father, finally stands up to him, he leaves home.

After the success of The Wizard of Oz (1939), the film was a "test" by MGM to evaluate both Garland's audience appeal and her physical image.

Let's say that "Little Nellie Kelly" is a pleasant picture for the family trade, and then let's give three cheers for good old gentle St. Mick.”[7] The film was released on DVD on March 15, 2011.
