Sylvain Creuzevault began directing in 2003, with the group d'ores et déjà, of which he is a co-founder. He made a name for himself in 2009 with Notre terreur at La Colline, a play about the Comité de salut public in 1793. This was followed by two shows on Marx (Le Capital et son Singe in 2014, Banquet Capital in 2018) and in 2016 Angelus Novus AntiFaust.
Associate artist at the Odéon-Théâtre de l'Europe since 2016 with his company Le Singe, he is devoting a cycle to Dostoyevsky, creating The Demons, The Grand Inquisitor and The Brothers Karamazov from 2018 to 2021. In 2023, he creates Edelweiss [France Fascisme], the counterpart to Peter Weiss's L'Esthétique de la résistance, presented a few months earlier at the Théâtre national de Strasbourg.
