It was filmed partly on the French Riviera, which stood in for South America. Interiors were filmed at the Victorine Studios and at Pathé's studio in Paris. The film's sets were designed by the art director Max Douy. During production Becker used the pretext of filming to liaise between French Resistance groups in Paris and the South.
