Claude Chabrol made this film for an American company, Universal, and with some American and British actors in prominent roles. Each scene for the film was filmed in both French and English versions, with the result that it got widely released in Britain and America. The English-language version was mostly scripted by film critics. Chabrol, who spoke excellent English, was able to maintain complete artistic control over the project.
