The Philadelphia Story is a 1940 American romantic comedy film starring Cary Grant, Katharine Hepburn, James Stewart and Ruth Hussey. Directed by George Cukor, the film is based on the 1939 Broadway play of the same name by Philip Barry about a socialite whose wedding plans are complicated by the simultaneous arrival of her ex-husband and a tabloid magazine journalist. The socialite, played by Hepburn in both productions, was inspired by Helen Hope Montgomery Scott (1904–1995), a Philadelphia heiress who had married Barry's friend.

Cary Grant was an English-American actor. He was known for his Mid-Atlantic accent, debonair demeanor, lighthearted approach to acting, and sense of comic timing. He was one of classic Hollywood's definitive leading men. He was nominated twice for the Academy Award, received an Academy Honorary Award in 1970, and received the Kennedy Center Honor in 1981. He was named the second greatest male star of the Golden Age of Hollywood by the American Film Institute in 1999.
