In September of that year, he established a freelance practice, working on commercials for clients such as Principality, Renault, Swinton and Swissair.

In 1991, Chomet started work on his first animated film, The Old Lady and the Pigeons, with backgrounds designed by Nicolas de Crécy.

[1] Upon the film's release, de Crécy accused Chomet of plagiarizing his work, citing it as the reason for the dissolution of their collaboration.

[2][3] The visual style of The Triplets of Belleville closely resembles the earlier work of de Crécy's 1994 graphic novel Le Bibendum Céleste.

Chomet says that "Tati wanted to move from purely visual comedy and try an emotionally deeper story" and states that "It's not a romance, it's more the relationship between a dad and a daughter".

Filming on Chomet's live action romantic musical-comedy Attila Marcel took place in Paris from mid-July 2012 and lasted 46 days.

[14] It premiered in the Special Presentation section at the 2013 Toronto International Film Festival,[15] and was released theatrically in France by Pathé in October that year.

The film's production was marred by disagreements and malpractice, or accusations thereof, between the French, British and North American staff involved.

Chomet came up against creative and ethical differences with the producers and was eventually fired from the project and thrown out of the studio space allocated to the film.

[27] In 2014, Chomet announced plans to direct The Thousand Miles, a mix of live-action and animation based on various works of Federico Fellini, including his "unpublished drawings and writings", with a screenplay by Tommaso Rossellini and Demian Gregory.

On January 5, 2016, Variety reported that Chomet was moving forward with the film after a lengthy development process, and was expected for a 2017 release.
