Actor, composer and screenwriter, Arthur pilfered a diploma as an assistant director in 2010, after two years of study at the École Supérieur d'Arts Cinématographique (ESEC).

His first appearance on screen was in "Pieds Nus sur les Limaces" by Fabienne Berthaud. Subsequently, he made numerous appearances on television in series such as "Working Girls" by Sylvain Fusse (2011), "Alias ​​Caracalla" by Alain Tasma, "Platan" by Eric Judor (2012), "Lettres à France" by Stéphane Clavier (2014), and Scènes de Ménage (2014-2023).

In cinema, he appeared for Catherine Corsini in "Les 3 Mondes" (2011), but also in "Baby Balloon" by Stefan Liberski and Dominique Laroche (2013), as well as many others. In 2016, he had the chance to be alongside Louis Garrel and Stacy Martin in "Le Redoutable", directed by Oscar-winner Michel Hazavanicius. In 2021, he reunited with Garrel for the second time for the film "L'Envol", by Pietro Marcello.

Maintaining a presence on the small screen, Arthur allowed himself a stint in English. He went to London and then Morocco for "SAS: Rogue Heroes", a BBC series directed by Tom Shankland and written by Steven Knight. In 2022-23, he played the Count of Ségur for Tim Van Patten in "Chapeau AKA The Grand Master, Franklin in Paris". He then slipped into the middle of a four-star cast including Noah Jupe, Ludivine Sagnier, Thibault de Montalembert and Michael Douglas.

If the theater seems to be left behind, he still plays "Les Désaccordés", by Marine Léonardi and Alexis Troccaz at the Théâtre Clavel. This season, he joined the Pipo Company troupe and took on the role of Valérian Olympovitch in “Le Mandat” by Thomas Erdman, under the direction of Patrick Pineau.
