Hayao Miyazaki’s The Boy and the Heron will premiere in Colombia on January 25. Ahead of that debut, the film is getting an unplanned and likely unappreciated marketing push, as a local woman has gone viral for convincing major media outlets that she drew around 25,000 frames for the film’s production.
As far as I know no, in traditional animation every frame is done in one go, except when there’s CGI involved (and even in that case there’s just one person “drawing”).
