Le Voyou, also known as The Crook, is a 1970 French action film which follows Simon the Swiss during his largest heist. Directed by Claude Lelouch in 1970, and starring Jean-Louis Trintignant, the film makes use of several cinematic techniques to convey the elusive nature of the title character, including a circular narrative, dialogue littered with conflicting statements, flashbacks, musical montage, multiple styles of film editing, misaligned sound editing, and movie within the movie.
