Classe tous risques ([klas tu ʁisk]; literally "All-Risk Class", but also a pun on the French expression "Classe Touriste", Economy Class), which was first released in the United States as The Big Risk, is a 1960 French-Italian gangster film directed by Claude Sautet and starring Lino Ventura, Jean-Paul Belmondo and Sandra Milo. An adaptation of the novel of the same name by José Giovanni, who collaborated with Sautet and Pascal Jardin on the screenplay, the film tells the story of a French mobster on the run with his family, who returns to Paris with help from a new criminal acquaintance and confronts the members of his old gang.

Now widely considered a masterpiece, at the time of its release, the film was somewhat overshadowed by the French New Wave. However, it did influence French cinema, especially Jean-Pierre Melville's subsequent work.
