Who’s That Girl is a 1987 American romantic comedy film written by Andrew Smith and Ken Finkleman, and directed by James Foley. It stars Madonna and Griffin Dunne, and depicts the story of a street-smart girl, who is falsely accused of murdering her boyfriend and is sent to jail. After getting released, she meets a man, who is supposed to make sure she gets on her bus back to Philadelphia, and convinces him to help her catch those responsible for her confinement. While searching for the embezzler, they fall in love with each other.

After the box-office failure of her 1986 film Shanghai Surprise, Madonna decided to sign another comedy film titled Slammer, which was later renamed to Who’s That Girl. However, she had to convince both Warner Bros. and the producers of the film that she was ready for the project. Madonna enlisted her friend James Foley to direct the film. Shooting began in New York in October 1986, and continued until March 1987. Production was halted during December due to snowfall in New York. Madonna utilized the time to work on her next tour and the soundtrack of the film.

The film, released on August 7, 1987, ended up being a critical and commercial failure. It grossed $2.5 million in its first week, while its domestic total was about $7.3 million. Reviewers were highly disappointed with the film, and Foley’s direction. Some went on to call it one of the worst films to be released, while others found Madonna’s comic timing to be one of the highlights.

However, the Who’s That Girl World Tour went on to be a critical and commercial success, grossing a total of US $25 million, and playing in front of 1.5 million audiences. And the soundtrack of the film, though not acclaimed by the critics, enjoyed commercial success. Three of Madonna’s songs were released as singles—the title track, “Causing a Commotion” and “The Look of Love”, and the album went on to sell six million copies worldwide.
