His inventions and his gaffophone leap from the world of comics to the Peticoin offices: Gaston Lagaffe is airing on 6ter on Tuesday, October 27, 2026 at 8:50 PM. Théo Fernandez stars as Gaston in Pierre-François Martin-Laval’s film, released in French cinemas on April 4, 2018.
Gaston arrives as an intern at the company, and his makeshift fixes turn his colleagues' daily routine on its head. The adaptation keeps Franquin’s characters intact: Prunelle is played by the director, Mademoiselle Jeanne by Alison Wheeler, Longtarin by Arnaud Ducret, and Monsieur De Mesmaeker by Jérôme Commandeur.
Born in the Journal de Spirou in 1957, Gaston hinges on the gap between his intentions and the disasters he unleashes. The film brings this world to life with a cast, following Les Profs, another comic-book adaptation directed by Pierre-François Martin-Laval.
