In the Spring of 2018, Félix Dutilloy-Liégeois wrote and directed, alongside Marguerite de Hillerin, Au Mont (At the Mount). In August 2019, Félix and Marguerite directed a medium-length film, Les Ruines en été (Ruins in Summer), which chronicles the return of a brother to a family bereaved by the son's death. This film allowed the duo to discuss certain fundamental themes of L’Enfant (The Child).
