Indian-origin director Mira Nair’s latest offering, “The Queen Of Katwe”, will have its world premiere at the Toronto International Film Festival (TIFF) in September. This  will be a gala presentation at the 41st edition of the premier movie event in North America. Nair’s previous feature, “The Reluctant Fundamentalist”, also first showed at TIFF in 2012.  Termed as a “vibrant true story”, the film tracks the unlikely path taken by 10-year-old Phiona Mutesi from the slum of Katwe in Kampala (Uganda’s capital ), to becoming a chess champion.
