In the late 1940s, Paul Grimault and screenwriter Jacques Preville conceived the animated feature film "The Shepherdess and the Chimney Sweeper" based on the fairy tale of Hans Christian Andersen. The film began production in 1947 with a production team of more than 100 people at most. By 1950, the film was less than 80% complete. Producer André Sarou, under financial pressure and despite the objections of Paul Grimault and screenwriter Jacques Pleville, finished the original draft of the film, which was officially released in 1952. The 62-minute "Shepherdess and the Chimney Sweep"released . In fact, Gurimo had lost control of the film since 1950, and he was adamantly opposed to the 62-minute version, arguing that at least 20 minutes should have been cut, so the film was far from his original intention.
