Only Kappei Yamaguchi, huh? Man, I hate how these "art" directors view professional Japanese voice actors. Miyazaki went so far as to say that Laren Bacall(who is not a VA) was preferable to female VAs in Japan. Most people in Japan don't care about voice actors, but from what I hear about these films, most otaku regard the voice acting as "bad" because these guys focus more on naturalism than believable performances and the fact that they use green VOICE ACTORS! As little as I know about Japanese voice acting, I can at least hear something. Life, passion, excitement. These drama actors cannot voice act worth a darn. These are household names, not VAs. Stick to using real VAs, please, otherwise part of your film is going to suck. Even Oshii's GITS used some of the best Japanese talent available, such as Yamadera, Tanaka and Otsuka. Follow that path.
