I am trying to encourage a young friend to learn chess. He is very interested, just like any child would be with a child's play. I am wondering which movie about chess to choose, that could cause more interest and improved learning to him.
In addition to great suggestion by Mark. You can also try Brooklyn Castle: http://www.imdb.com/title/tt1800266/
It seems quite inspirational, the main message 'it's also cool to play chess'.
A movie that I like about chess is "The Luzhin Defense".
However, the movie might encourage your friend not to be obsessive with chess. Anyhow, the tactical problems showed in the movie deserves a view if you are yet a chess player.
