Judy Holliday's last film before dying of breast cancer just two weeks before her 44th birthday in New York City on June 7, 1965.
Except for two uncredited parts in her first two films, this was the only color film Judy Holliday made.
Frank Gorshin (Blake Barton) is doing an impression of Marlon Brando. Gorshin was one of Hollywood's greatest impressionists, along with Rich Little. He would become famous for playing "The Riddler" on Batman (1966), appearing in ten episodes, and a role for which he was nominated for an Emmy.
Judy Holliday won Broadway's 1957 Tony Award as Best Actress (Musical) for "Bells Are Ringing," a role she recreates in this film version.
