It seems apt at this point having raised funds for African Xplorers trip to Kenya with a chess competition to recommend a fairly recent Disney film called Queen of Katwe.
It's about a girl who lives in poverty in Uganda and gets the opportunity to learn how to play chess and her struggles to compete in competitions.
Think the kids would enjoy it (and maybe the adults as well).
As an aside one of the kids who starred in the film died yesterday aged just 15. How very sad.
The following link gives you some detail about the film.
