Twilight of Honor, released in the UK as The Charge is Murder, is a 1963 American neo noir crime film directed by Boris Sagal and starring Richard Chamberlain, Nick Adams, Claude Rains, and featuring Joey Heatherton and Linda Evans in their film debuts. Twilight of Honor is a courtroom drama based on Al Dewlen's novel, with a screenplay by Henry Denker. Like the 1959 courtroom drama Anatomy of a Murder, it continued a recent trend of descriptions of things previously never mentioned in American cinema, such as vivid accounts of sexual assault, adultery, and prostitution.

George Richard Chamberlain is an American actor and singer who became a teen idol in the title role of the television show Dr. Kildare (1961–1966). He subsequently appeared in several miniseries, such as Shōgun (1980) and The Thorn Birds (1983) and was the first to play Jason Bourne in the 1988 television film The Bourne Identity. Chamberlain has also performed classical stage roles and worked in musical theatre.
