The Trial (French: Le Procès) is a 1962 surrealist drama film written and directed by Orson Welles, based on the 1925 posthumously published novel of the same name by Franz Kafka. Welles stated immediately after completing the film: "The Trial is the best film I have ever made". The film begins with Welles narrating Kafka's parable "Before the Law" to pinscreen scenes created by the artists Alexandre Alexeieff and Claire Parker.

Anthony Perkins stars as Josef K., a bureaucrat who is accused of a never-specified crime, and Jeanne Moreau, Romy Schneider and Elsa Martinelli play women who become involved in various ways in Josef's trial and life. Welles plays the Advocate, Josef's lawyer and the film's principal antagonist.

The Trial has grown in reputation over the years, and some critics, including Roger Ebert, have called it a masterpiece. It is often praised for its scenic design and cinematography, the latter of which includes disorienting camera angles and unconventional use of focus.
