When François de Capestan rescue Gisèle d'Angoulême from the castle, in the exterior shots you can see that Elsa Martinelli was replaced by a stand-in actress wearing a wig. The double tried in these shots to hide her face or she was always shown her back to the camera. After they cross the river, Martinelli appears.
Although it is an action and adventure film, there are two musical moments performed by Bourvil and Pierrette Bruno.
