The Cardinal in the context of "Academy Awards"

Charles Hart (bap. 1625 – 18 August 1683) was a prominent English Restoration actor.

A Charles Hart was christened on 11 December 1625, in the parish of St. Giles Cripplegate, in London. It is not absolutely certain that this was the actor, though the name was not common at the time.. He was most likely the son of William Hart, a minor actor with the King's Men. Hart began his career as a boy player with the King's Men; he was an apprentice of Richard Robinson, longtime member of that company. Hart established his reputation by playing the role of the Duchess in The Cardinal, the tragedy by James Shirley, in 1641. James Wright says in Historia Histrionica that: "Hart and Clun, were bred up Boys at the Blackfriers; and Acted Womens Parts, Hart was [Richard] Robinson's Boy or Apprentice: He Acted the Dutchess in the Tragedy of the Cardinal, which was the first Part that gave him Reputation."

Thomas Lester Tryon (January 14, 1926 – September 4, 1991) was an American actor and novelist. As an actor, he was billed as Tom Tryon and is best known for playing the title role in the film The Cardinal (1963), featured roles in the war films The Longest Day (1962) and In Harm's Way (1965), acting with John Wayne in both movies, and especially the Walt Disney television character Texas John Slaughter (1958–1961). Tryon later turned to the writing of prose fiction and screenplays, and wrote several successful science fiction, horror and mystery novels as Thomas Tryon.

Marguerite McNamara (June 18, 1928 – February 18, 1978) was an American stage, film, and television actress and model. McNamara began her career as a teenage fashion model. She first came to public attention as Patty O'Neill in the 1951 national tour of F. Hugh Herbert's The Moon Is Blue which ran concurrently with the original Broadway production. In 1952 she succeeded Barbara Bel Geddes in that role in the Broadway production. Both productions were directed by Otto Preminger, and Preminger also directed McNamara in that role in the controversial 1953 film adaptation of that work. She earned an Academy Award nomination for Best Actress for her role in the film.

She appeared in only three films after The Moon Is Blue, with her last being The Cardinal in 1963. After five guest-starring roles in television series in the early 1960s, she retired from acting. For the remainder of her life, she worked as a typist in New York City. On February 18, 1978, McNamara died of an intentional barbiturate overdose at the age of 49.
