Macao or Gambling Hell (French: Macao, l'enfer du jeu) is a 1942 French drama film directed by Jean Delannoy and starring Sessue Hayakawa, Mireille Balin and Henri Guisol. It is based on the 1938 novel of the same title by Maurice Dekobra. It was shot at the Victorine Studios in Nice. The film's sets were designed by the art director Serge Piménoff. When production began in 1939, Erich von Stroheim was cast in the role of Werner von Krall. Production delays and the German occupation of France in 1940, meant that the film's completion and release was delayed. The scenes with Von Stroheim had to be re-shot at Cité Elgé in Paris, with Pierre Renoir taking over the role for a 1942 release. Only after the Liberation was the original version screened.
In the near lawless port of Macao, arms dealer Werner Von Krall rescues singer Mireille from a firing squad. He soon enters into a weapons deal with casino owner Yin Tchaï, who hides his criminal life from his daughter Jasmine. When the deal fails and his debts mount, Von Krall kidnaps Jasmine to force an escape. Their conflict reaches a climax that forces both men to face the consequences of their trade.
