In 1972, the stage musical adaptation was in turn adapted as a film directed by Bob Fosse. The 1972 film's depiction of Sally significantly differs from earlier incarnations in that she is not British but American. According to unaccredited screenwriter Hugh Wheeler, he was tasked by ABC Pictures with bowdlerizing the source material and was forced to change Sally's nationality as well as to transform her into a noble heroine in order to increase the film's commercial appeal. Key dialogue was likewise altered to make Sally appear more bisexual.
