The biggest considerations I had were practical: how do you move such a large number of actors around a small space? So, for example, if I have to have the mother bring a pot of tea from the kitchen to the living room and serve it to the others, how do I, on a practical level, get everyone into the frame? Any decisions I made about the camera angles or movement came out of necessity, versus any sort of stylistic choice.

As far as documentaries go, I believe unreservedly that they serve an important function in our culture. I'd love to be able to make both documentaries and feature films simultaneously, but so far that hasn't happened.

In order to avoid sentimentality and to be able to write the screenplay with the kind of humor and irony necessary to keep the story moving, I needed to distance myself as much as I could from the characters, to try to get to a point where I could view them objectively.

If a movie is nominated for, say, an Academy award, that movie will instantly become popular in Japan. There's always been a bit of a complex the Japanese have about being taken seriously in the West.

The contemporary Japanese directors who are well-known in the West - say, Kiyoshi Kurosawa, Takeshi Kitano, Naomi Kawase - are mostly unknown to Japanese, particularly of the younger generation.

One of the more problematic aspects of the current state of cinema in Japan is that the movies playing in the theaters are by and large made not by film studios but by broadcasting companies. They're either extensions of popular television dramas or adaptations of manga or anime. Younger Japanese are simply not being exposed to good films. That situation needs to change.

I did want to become a novelist, but the program at Waseda was pretty intense in terms of language requirements - two hours of English and four hours of Chinese. I thought, what do I need this for? So I stopped going to class.
