The Twelve Tasks of Asterix ("Les Douze travaux d'Astérix") is a 1976 Belgian/French animated feature film based on the "Asterix" comic book series. René Goscinny and Albert Uderzo, the creators of the series, wrote the story and directed the film themselves; with co-direction by Pierre Watrin and the screenplay co-written by Pierre Tchernia, a friend of Goscinny and Uderzo. The film was directed, produced and animated at Goscinny and Uderzo's own animation studio, Studios Idéfix and is the only Asterix animated film that has used the Xerography Process. At the time of its release, the film received mixed reviews since its tone is more cartoony and frequently breaks the fourth wall. Nowadays its reception is more favorable, with it often being cited as one of the best "Astérix" films, even reaching the status of a cult classic.
