The Origin of Evil (French: L'Origine du mal) is a French and Canadian thriller drama film, directed by Sébastien Marnier and released in 2022.^[3] The film stars Laure Calamy as Nathalie, a con-woman who assumes her imprisoned lover's identity as the biological daughter of wealthy businessman Serge Dumontet (Jacques Weber), and attempts to fit in with his established family despite their unwillingness to accept her.^[4]

The cast also includes Dominique Blanc, Suzanne Clément, Doria Tillier, Naidra Ayadi, Clotilde Mollet, Céleste Brunnquell and Véronique Ruggia.

The film premiered on 1 September 2022 at the 79th Venice International Film Festival,^[3] and had its North American premiere at the 2022 Toronto International Film Festival,^[5] in advance of its commercial release in October.

According to Marnier, the film was initially inspired by his own mother's story of having never known her biological father and meeting him only as an adult, but cautioned that the overall film should not be interpreted as a portrait of his own family.^[6]

In an interview with Fugues magazine, he noted that he had made the film as a France-Canada coproduction because he was interested in working with several figures from Quebec, including musicians Philippe Brault and Pierre Lapointe and sound editor Sylvain Bellemare, who brought a more North American, rather than European, approach to film sound.^[7]

David Katz of Cineuropa wrote that the film "feels like the sort of movie you might’ve caught half-asleep on late-night TV in the pre-streaming age, perhaps after having missed the first 15 minutes – forcing you to stay glued until the very end, drooping eyelids be damned. Or, to be less flattering, it feels like the kind of brisk, undemanding, back-of-the-seat entertainment that might make a few hours of a long-haul flight melt away."^[3]

For Screen Daily, Allan Hunter wrote that "Marnier’s agile screenplay takes us beyond surface appearances to reveal the hidden agendas at play. Propelled by revelations, twists and a seasoning of sly humour, The Origin Of Evil is very watchable, even if some ingredients propel it towards parody. The mention of a secret passage and the rumbles of thunder to signal the coming denouement over egg pudding, not to mention the score by Philippe Brault and Pierre Lapointe, flirt with Victorian melodrama."^[8]

The film was the winner of the Audience Award for Narrative Features at the 2023 Frameline Film Festival.^[9]
