Are there any movies about chess in which World Champions or grandmasters have played actually any role? For example, have Kasparov, Karpov, Anand, Carlsen, Kramnik, Polgar, Fischer, Tal or etc acted in the movie?
Check out Grossmeyster. Mikhail Tal exchanges a few words with the main character. Keres, Kotov, Taymanov, Averbakh have cameo appearances. Victor Korchnoj plays the main character's coach.
I don't know if the English version exists.
The 1993 American drama film “Searching For Bobby Fischer”, based on the book with the same, has a few cameos by grandmasters. Here is a list of them per Wikipedia.
