The budget focused on the animation. In the background, the characters have a very distinct style, which is not usual in anime, but more common in Western cartoons. Before working on this movie, Telecom Animation Film had done projects in the West, such as "The Real Ghostbusters" and "DuckTales". Two of their employees were Hayao Miyazaki and Yasuo Ōtsuka, who is the supervisor of this film. Lupin's cars are based on the vehicles owned by Hayao Miyazaki, a Citroen 2CV, and Yasuo Ōtsuka, a Fiat 500. By using their own cars as models, they were able to keep the animation consistent throughout production.
