"The Wind Rises" is a highly fictionalized version of the early years of aeronautical engineers Jiro Hirokoshi and Tatsuo Hori...with a very strong emphasis on Jiro. The fact Hiyao Miyazaki would make such a film isn't all that surprising, since he seemed to have a real sentimental attitude towards early airplanes in several of his films (such as "Porco Rosso"). However, I was a bit surprised when I learned about the film since the planes these two men made for Mitsubishi were important components of the extremely nationalistic Japanese military of the 1930s and 40s...an era many would probably choose to forget.
Not surprisingly, this is a Miyazaki film that is not at all intended for children. In fact, I wouldn't bother showing it to your younger audiences...they'd be bored. Plus some parents would object to all the smoking and cursing...and there's not a single Totoro or flying witch to be seen! As for me, I understand that many Japanese animated films are NOT intended for kids and that isn't a bad thing at all. In this case, Studio Ghibli managed to make one of the loveliest of all their films in "The Wind Rises". It is extremely touching in parts, especially when dealing with Jiro's fated romance. In fact, the film practically screams quality throughout and it's not at all surprising that it was nominated for the Best Animated Feature Oscar. Well worth seeing.
Incidentally, Jiro's infamous Japanese Zero was interesting because by the end of the war almost every single one of these aircraft had been destroyed...and I wonder how he felt about this. Ironically, one of the few Zeros to survive did so because it was captured and taken to the States for testing and evaluation.
