Dark of the Sun (also known as The Mercenaries in the UK) is a 1968 British adventure war film starring Rod Taylor, Yvette Mimieux, Jim Brown, and Peter Carsten. The film, which was directed by Jack Cardiff, is based on Wilbur Smith's 1965 novel, The Dark of the Sun. The story about a band of mercenaries sent on a dangerous mission during the Congo Crisis was adapted into a screenplay by Ranald MacDougall. Critics condemned the film on its original release for its graphic scenes of violence and torture.
