Chabrol before he truly became Chabrol. This might seem to be one of his more 'realistic' films, with its obligatory nouvelle vague scene of Parisian freewheeling, but one of 'Les Cousins'' main themes is the disparity between reality and fantasy, and the fate of those who cannot tell between them. Just as paul turns his personality into a series of roles, his life into ritualistic tableaux, so Chabrol suffuses his realistic narrative with references to myth, fable, fairy tale, opera, and, especially, film.
'Les Cousins' plays like a counterpart to Melville's 'Les Enfants Terribles', with the same theatricality, claustrophobia, incestuousness, and mythological base; the same cinematographer, even one of Melville's actors! most interesting is the development of Chabrol's style, the lockjaw camerawork, the complex use of point of view, the puncturing of solemnity with incongruous humour (see especially the hilarious 'fish' scene).
