Gilles Grangier tells in his biography that he directed this movie in the same time he also made L'Homme De Joie, in the same studio, but on two different sets, with Jean Pierre Aumont cast in both films. The experience was very stressful for all the crew in charge of the two simultaneous shootings. And Louis De Funès, who played in only one of the two features, played jokes on the set of the other film to confuse actor Jean-Pierre Aumont; just for fun.
