Nathan Ambrosioni, born in 1999, began honing his craft in cinema in 2014 and 2015 by directing two self-produced genre films during his school holidays. These projects went on to tour festivals worldwide, including Brussels, Los Angeles, Montreal, Barcelona, and Buenos Aires. In 2016, he shifted genres and wrote and directed the short film Ce qui nous reste with Zoé Adjani, which was selected at the Calgary and San Francisco festivals. In 2017, with support from the CNC, he produced his first feature, Paper Flags (Les Drapeaux de papier). In 2021, he wrote Toni, en famille, which he directed the following year with Camille Cottin in the lead role. The film earned him three awards at the 2023 Festival du film de demain : Best Film, Best Screenplay, and the Audience Award. In 2025, Ambrosioni worked with Camille Cottin again for his second feature film, Les enfants vont bien, for which he won the Best Director award at its world premiere in Karlovy Vary and the Valois de Diamant at the Angoulême Festival.
