I have used the film Tampopo to show modern, now 1980s, Japan. That is the point where Japan was at its richest, but the director makes a point of pointing out aspects of Japanese modern life that are both unique and familiar. It is a Japanese film, but has a strong French technical influence, while using the American Western genre to promote the hero, Goro. Like the Taiwanese film, Eat Drink Man Woman, it centers on food, something that students can relate to, though maybe surprised as well.
There is a lot going on. My current school's schedule does not allow for this movie to be shown in world history (we have only 20 weeks to cover it all).
I would use it in a cultural geography course, however, and get much covered as a result.
