It is very easy to get sidetracked while travelling the world wide web. Earlier today I noticed a story on the 50 Greatest Movies of All Time (Sight & Sound magazine), and I wondered what the greatest chess movies were. Plugging in my query into the very trusty google, I discovered the top result was a previous post on this very blog! Fortunately the second result turned up something far more interesting.
"The Great Chess Movie". It is a Canadian documentary made in 1982, and covers the chess scene both from an historical and contemporary (1970's) point of view. The film 'stars' Fischer, Korchnoi and Karpov, along with a host of other chess players included in the footage.
I'm a little surprised that I don't seem to remember this film, although this may be case of forgotten discovery, rather than not knowing about it at all. If you wish to view it someone has helpfully put it up on youtube (in three parts). The first part is here, and there are links to the other parts from this page.
