Back when it was first revealed animation god Hayao Miyazaki was making that film about the designer of Japan's WWII fighter, the Mitsubishi A6M Zero, a Studio Ghibli producer described it as "not the sort of work that everyone in the audience can relax and watch." That statement would seem to be confirmed with this first trailer for the film, which, despite being in Japanese, definitely communicates a deep sense of wistfulness, tears, and--holy shit! At the end! Not the face!!!
