Nada is a political thriller film released in 1974, directed by the French filmmaker Claude Chabrol. The screenplay, co-written by Chabrol and Jean-Patrick Manchette, is based on Manchette’s 1972 novel of the same name. The film is a co-production between French and Italian film companies.
The narrative follows a group of militant anarchists, known as the "Nada group," who orchestrate the kidnapping of the United States Ambassador to France from a high-end Parisian brothel. The plot details the group's internal ideological conflicts and the subsequent response by the French authorities. The film is noted for its objective portrayal of both the revolutionaries and the state, depicting the violent tactics of the police and the tactical failures of the insurgents with a neutral, often cynical perspective.
The cast features Fabio Testi, Maurice Garrel, Mariangela Melato, Michel Duchaussoy, and Lou Castel. The cinematography was handled by Jean Rabier, a frequent collaborator of Chabrol. Upon its release, Nada was recognized for its departure from Chabrol's typical focus on bourgeois domestic dramas, instead engaging directly with the contemporary political climate and the rise of radical militancy in Western Europe during the 1970s.
