This Man Must Die (French: Que la bête meure ), American title The Beast Must Die, is a 1969 French and Italian thriller film directed by Claude Chabrol.

The King Must Die is a 1958 bildungsroman and historical novel by Mary Renault that traces the early life and adventures of Theseus, a hero in Greek mythology.
 Naturally, it is set in Ancient Greece: Troizen, Corinth, Eleusis, Athens, Knossos in Crete, and Naxos.
 Rather than retelling the myth, Renault constructs an archaeologically and anthropologically plausible story that might have developed into the myth.
 She captures the essentials while removing the more fantastical elements, such as monsters and the appearances of gods.

 Renault wrote a sequel, "The Bull from the Sea", in 1962.
