Curiosa is a 2019 French biographical film directed by Lou Jeunet starring Noémie Merlant, Niels Schneider and Benjamin Lavernhe. It is loosely based on the relationship between 19th-century French authors Pierre Louÿs and Marie de Régnier. Pierre Louÿs was an erotomaniac who took erotic or pornographic photographs of his mistresses. Such erotic or even pornographic representations are referred to as 'curiosa'’, hence the name of the movie.
