Web of Passion (À double tour)

À double tour arrived in 1959 as a French-Italian psychological thriller, also classed as a crime drama. It was directed by Claude Chabrol, though one source names Philippe de Broca as a co-director. The film is adapted from the American writer Stanley Ellin's 1952 novel The Key to Nicholas Street, and the screenplay credits Chabrol and Paul Gégauff. It was Chabrol's first colour film and his first thriller, a genre he kept to for the rest of his career. It sold 1,445,587 tickets in France. Internationally it circulated as Web of Passion and Leda, in Germany as Schritte ohne Spur and in Italy as A doppia mandata, in Spain as Una doble vida and in Argentina as Doble vida.

The leads are Antonella Lualdi, Jean-Paul Belmondo, Bernadette Lafont and Madeleine Robinson; Mario David, Jacques Dacqmine and Jeanne Valérie also appear, and Claude Chabrol himself is credited in the cast. The film is known as the one that first brought Belmondo to a wider audience. Raymond Hakim produced it and Paul Misraki wrote the music; the production company is Titanus. It runs 94 minutes.
