Jean-Paul Belmondo plays a character named Laszlo Kovacs, which was the alias of his character Michel Poiccard in Breathless (1960).
Director Claude Chabrol originally intended on casting Sue Parker and Charles Boyer in the roles eventually played by Antonella Lualdi and Jacques Dacqmine, but neither decision worked out.
Jean-Claude Brialy, who had starred in Claude Chabrol's Le Beau Serge (1958) and The Cousins (1959), was originally supposed to play the part of Laszlo Kovacs but fell ill before filming began. Jean-Paul Belmondo was brought on as a last minute replacement to play his first major role.
À double tour (1959) was the first psychological thriller by Claude Chabrol which would come to predominate his career. The film introduces themes and motifs which would recur regularly in his work, such as an interest in mental derangement and bourgeois duplicity.
Madeleine Robinson won the Volpi Cup for Best Actress in 1959 for her role in this film.
