Chess in Film by Egantx7

Question 5

There is a longstanding rumor, never confirmed, that the correspondence game between Sebastian and Tyrell in this film is based on the famous "Immortal Game" played by Anderssen and Kieseritzky in 1851, something that would fit with one of the film's themes. Sebastian uses the guise of making a move in person to introduce Roy to Tyrell; a meeting which results in Roy killing both Sebastian and Tyrell. Identify this 1982 film-noir classic which stars Harrison Ford as a special law enforcement officer (or is he?)
