The film Mikan no Taikyoku ("The Go Masters") was directed by Ji-shun Duan (or Duah) and Junya Sato in 1982. It is very loosely based on some incidents from the life of Go Seigen, about ten years before World War II began. A Japanese master of Go and a very strong Chinese prodigy play a game in China.
This film was a co-production between Japan and China, the first, which was a revolution in international relations. Yu pan mei you xia wan de qi (Mandarin title), 123 minutes.
Roger Ebert gave it three and a half stars in 1986. He was on the jury that gave it First Prize at the Montreal Film Festival.
Internet Movie Database Entry
gives it a high rating.
Go Seigen apparently does not like this movie. By contrast, he is working with the producers of the new movie being made now (2004). This is from an interview he gave in 1983 (thanks to John Fairbairn for posting on r.g.g):
T: Last year I saw the acclaimed film - a Sino-Japanese joint venture - "The unfinished game". It involves a young genius from China who wanted to be a professional go player in Japan before the war, who came to Tokyo to study, and who finally conquered the professional go world. It sketches the relationships beyween go players in Japan and China and so in part at least you must have been the model.
G: Yes. I was shown a scenario before the film was made, and there are characters similar to me and my teacher Segoe (Kensaku, 9d). But I died when I was young and my teacher went mad, so it is not all a true story.
That film was also shown overseas and a Taiwanese police chief saw it and took it for granted that I had died. When he happened to come to Tokyo recently, we met. Well, he was so overjoyed that I was alive and well, he hugged me! (laughs)
Hans-Georg: A heavily compressed DivX AVI file of this movie (300 MB for 2 hours, 15 minutes [differs from IMDB and Ebert timing]) can be found on some servers that also carry the Hikaru no Go series (like ftp.hikago.flirble.org under Misc). But be warned: the quality of the file is very bad. Not only is the resolution very low and the entire movie full of compression artifacts, but, worse, the contrast is so extreme that much of the dark or bright scenes is invisible as pure black or white. The worst, however, is that the sound is initially synchronized with the video but drifts until it is some 10 seconds late at the end of the movie. This last defect is particularly insidious because you don't notice it when you check the beginning.
In other words, I cannot recommend downloading and watching it unless you're very desperate.
This is a pity. If anybody finds or creates a better video file, which with current compression technology should be some 1.3 to 2 GB in size, I would be very interested.
