Chomet's first feature-length animated film, The Triplets of Belleville (Les Triplettes de Belleville, or Belleville Rendez-vous in the UK) was also nominated for two Oscars in 2003 (Best Animated Feature and Best Song), and introduced Chomet's name to a much wider audience.
Upon the release of The Triplets of Belleville Nicolas De Crécy accused Chomet of plagarising his work, citing it as the reason for the dissolution of their collaboration. The visual style of Les Triplettes de Belleville closely resembles the earlier work of Nicolas De Crécy's 1994 graphic novel Le Bibendum Céleste.
