Dangerous Moves (French: La Diagonale du fou) is a 1984 French-language film about chess, directed by Richard Dembo, produced by Arthur Cohn, starring Michel Piccoli, Alexandre Arbatt, as well as Liv Ullmann, Leslie Caron, and Bernhard Wicki in prominent supporting roles.
Its original French title is La diagonale du fou ("The Fool's Diagonal", referring to the chess piece called the bishop in English but the fool in French). The film was a co-production between companies in France and Switzerland. It tells the story of two very different men competing in the final match of the World Chess Championship. One is a 52-year-old Soviet Jew who holds the title, and the other is a 35-year-old genius who defected to the West several years earlier.
