Pretty Woman is a 1990 American romantic comedy film directed by Garry Marshall, from a screenplay by J. F. Lawton. The film stars Richard Gere and Julia Roberts, and features Héctor Elizondo, Ralph Bellamy (in his final performance), Laura San Giacomo, and Jason Alexander in supporting roles. The film's story centers on Hollywood escort Vivian Ward and wealthy businessman Edward Lewis. Vivian is hired to be Edward's escort for several business and social functions, and their relationship develops during her week-long stay with him. The film's title Pretty Woman is based on the 1964 song "Oh, Pretty Woman" by Roy Orbison. The original screenplay was titled “3,000”, and was written by then-struggling screenwriter J. F. Lawton.

Originally intended to be a dark cautionary tale about class and sex work in Los Angeles, the film was re-conceived as a romantic comedy with a large budget. The film received generally positive reviews, and Roberts received a Golden Globe Award for Best Actress in a Motion Picture – Musical or Comedy and a nomination for the Academy Award for Best Actress for her performance, which catapulted her to superstardom. In addition, screenwriter J. F. Lawton was nominated for a Writers Guild Award and a BAFTA Award. The film saw the highest number of ticket sales in the US ever for a romantic comedy, with Box Office Mojo listing it as the number-one romantic comedy by the highest estimated domestic tickets sold at 42,176,400, slightly ahead of My Big Fat Greek Wedding (2002) at 41,419,500 tickets. The film grossed US$463.4 million worldwide and at the time of its release, was the fourth-highest-grossing film of all time worldwide, behind only E.T. the Extra-Terrestrial ($619 million at the time), Star Wars ($530 million at the time) and Indiana Jones and the Last Crusade ($474 million at the time).
