The Lion in Winter is a 1966 play by James Goldman, depicting the personal and political conflicts of Henry II of England, his wife Eleanor of Aquitaine, their children and their guests during Christmas, 1183. It premiered on Broadway at the Ambassador Theatre on 3 March 1966, starring Robert Preston and Rosemary Harris, who won a Tony Award for her portrayal of Eleanor. It was adapted by Goldman into an Academy Award-winning 1968 film of the same name, starring Peter O'Toole and Katharine Hepburn. The play has been produced numerous times, including Broadway and West End revivals.

Set during Christmas 1183 at Henry II of England's castle in Chinon, Anjou, Angevin Empire, the play opens with the arrival of Henry's wife Eleanor of Aquitaine, whom he has had imprisoned since 1173. The story concerns the gamesmanship between Henry, Eleanor, their three surviving sons Richard, Geoffrey, and John, their guest, Philip II of France (the son of Eleanor's ex-husband, Louis VII of France). Also involved is Philip's half-sister Alais, who has been at court since she was betrothed to Richard at age eight, but has since become Henry's mistress.

Spencer Bonaventure Tracy (April 5, 1900 – June 10, 1967) was an American actor. Respected for his natural style and versatility, Tracy was one of the major stars of Hollywood's Golden Age. In a screen career that spanned 37 years, he was nominated for nine Academy Awards for Best Actor—a record he holds with Laurence Olivier—of which he won two.

Tracy discovered his talent for acting while a student at Ripon College, and subsequently gained a scholarship for the American Academy of Dramatic Arts. He spent seven years in the theatre, working in a succession of stock companies and intermittently on Broadway. Tracy's breakthrough came in 1930, when his lead performance in The Last Mile caught the attention of Hollywood. After a successful film debut in Up the River, Tracy was signed to a contract with Fox Film Corporation. His five years with Fox were unremarkable, and he remained largely unknown to audiences after 25 films. In 1935, Tracy joined Metro-Goldwyn-Mayer, Hollywood's most prestigious studio. His career flourished with a series of hit films, and in 1937 and 1938 he won consecutive Oscars for Captains Courageous and Boys Town. By the 1940s, Tracy was one of the studio's top stars. In 1942 he appeared with Katharine Hepburn in Woman of the Year, beginning a popular partnership that produced nine movies over 25 years.

Archibald Alexander Leach (January 18, 1904 – November 29, 1986), better known by his stage name Cary Grant, was an English-American actor. Known for his transatlantic accent, debonair demeanor and "dashing good looks", Grant is considered one of classic Hollywood's definitive leading men.

Grant was named the second Greatest Male Star of All Time by the American Film Institute. Noted particularly for his work in comedy but also for drama, Grant's best-known films include The Awful Truth (1937), Bringing Up Baby (1938), Gunga Din (1939), The Philadelphia Story (1940), His Girl Friday (1940), Arsenic and Old Lace (1944), Notorious (1946), To Catch A Thief (1955), An Affair to Remember (1957), North by Northwest (1959) and Charade (1963).

Nominated twice for the Academy Award for Best Actor, for Penny Serenade (1941) and None But the Lonely Heart (1944), and five times for a Golden Globe Award for Best Actor, Grant was continually passed over, and in 1970 was given an Honorary Oscar at the 42nd Academy Awards. Frank Sinatra presented Grant with the award, "for his unique mastery of the art of screen acting with the respect and affection of his colleagues".
