Hayao Miyazaki was supposed to have retired years ago, but the world is grateful the man does not stop making movies. Animation Magazine reports that Miyazaki’s next film will focus on the life of Jiro Horikoshi, the designer of the Zero fighter plane used to bomb Pearl Harbor in December 1941. Horikoshi was an aeronautical engineer with many military aircraft on his resume. Miyazaki is renowned for his fantastical tales, but he said his new movie would be autobigraphical and “not the sort of work that everyone in the audience can relax and watch.” He is shifting his strengths, but Studio Ghibli did make Grave of the Fireflies.
