Manhattan lawyer Louden Trott (Griffin Dunne) is about to marry his tycoon boss Simon Worthington's (John McMartin's) spoiled-rotten daughter Wendy (Haviland Morris), albeit with a crushing prenuptial. Simon, however, makes him interrupt the preparations to make sure in person that nobody Nikki Finn (Madonna), just released from a New York jail, takes the bus to meet her Philadelphia parole officer. Picking up a cat (actually a rare mountain lion) for even richer Montgomery Bell (Sir John Mills) proves to be bad enough, but Nikki takes the cake when it comes to provoking, manipulating, and surprising. Furthermore, they are tailed by a couple of criminal goons and a bickering pair of police detectives who are after the key to evidence which Nikki claims proves she was framed by corrupt Worthington.

otsoNY Comments: Fans of Madonna will recognise this shot from the front cover of the "Who's That Girl" single, which was released in June 1987, by Sire Records as the first album single. The song was later included on the two-disc edition of Madonna's 2009 greatest hits album Celebration. While shooting for the film, Madonna had requested Patrick Leonard to develop an uptempo song that captured the nature of her film persona. She later added the lyrics and vocals to the demo tape developed by Leonard, and decided to rename the song as well as the film to "Who's That Girl". Featuring instrumentation from drums, bass, and stringed instruments, "Who's That Girl" continued Madonna's fascination with Hispanic culture by incorporating Spanish lyrics and using the effect of double vocals. Critical reception was mixed to positive; some critics compared it to Madonna's previous single, "La Isla Bonita", while others found it forgettable. "Who's That Girl" became Madonna's sixth single to top the Billboard Hot 100, while peaking atop the charts in countries like the United Kingdom, Canada, Netherlands, Ireland and Belgium.

otsoNY Comments: Costume Designer Deborah Lynn Scott was signed to create the wardrobe for this movie. Madonna, who visualized the character of Nikki as a dizzy screwball blonde, started watching the screwball comedies of the sixties, especially the work of actors and actresses like Cary Grant, Clark Gable, Carole Lombard, and Judy Holliday. She asked Scott to create comical rah-rah and ballet tutu skirts for the character, with fishnet tights and loud make-up. Scott also designed a glamorous Monroe-esque dress for the love scene between her and Griffin Dunne.
