Coming from the world of theater, his career started on stage. He made his debut in cinema in 2000 alongside Thierry Lhermitte in Le Roman de Lulu. He then moved from one film to the other, was popular in subordinate roles and gradually imposed his juvenile lead style among the new generation of French film actors.
In 2010 he was noticed as Karin Viard’s lover in Les Invités de mon père by Anne Le Ny and as the Duc D’Anjou in The Princess of Montpensier by Bertrand Tavernier. From that time on, it was impossible to avoid Raphaël Personnaz who monopolized the screens with: Trois Mondes by Catherine Corsini, Anna Karenine by Joe Wright, Forces spéciales by Stéphane Rybojad, La Stratégie de la poussette by Clément Michel, Marius et Fanny by Daniel Auteuil, Au bonheur des ogres by Nicolas Bary, Quai d’Orsay by Bertrand Tavernier. He won the Patrick Dewaere Prize in 2013. In 2014 he will be seen in new films by François Ozon (Une nouvelle amie) and Régis Wargnier (Le Temps des aveux).
