In the Good Old Summertime is a Charming and Romantic Musical

Judy Garland's name is synonymous with musicals during Hollywood's Golden Age. Her portrayal of Dorothy Gale in The Wizard of Oz (1939) was the role that launched her into stardom and is still the character she is most remembered for. 

 She made a string of  musicals post- Oz.  In the Good Old Summertime (1949) Garland and Van Johnson play rival sales clerks Veronica Fisher and Andrew "Andy" Larkin  by day and by night they are unknowingly involved in an anonymous, romantic, meeting of the minds, pen-pal relationship. Eventually, their mutual dislike of one another blossoms into romance.

In the Good Old Summertime is the perfect blend of charm, humor, and romance and  showcases Garland's voice and displays her humorous side. Johnson and Garland have natural and engaging chemistry throughout the film.
If musicals are a genre of films you love I'd urge you to add In the Good Old Summertime to your list.

Fun Film Trivia: In the Good Old Summertime was Liza Minnelli's (Judy's daughter) film debut at 3 years old. She appears with her mother and Johnson in the final scene.
