The documentary film Chess: A State of Mind came out in 1986 and was written by British IM William Hartston. This (almost) 30-minute piece offers a recap of the world championship from Paul Morphy (not an official champion) through the beginning of the Garry Kasparov era. It goes from Morphy through Boris Spassky pretty quickly, and then takes its time with Bobby Fischer and Anatoly Karpov. Viktor Korchnoi gets a lot of air time in the Karpov segment, and both Korchnoi and Spassky have a bit of fun at Karpov's expense.
Young whippersnappers should watch for the history lesson, and oldsters should watch for the nostalgia.
