Oscar winner Lupita Nyong'o will be joined by British star David Oyelowo for the premiere of their new movie Queen Of Katwe.
The pair star in the film which tells the true story of a young Ugandan chess champion.
Nyong'o, who scored an Academy Award for her role in 12 Years A Slave, plays the mother of 10-year-old Phiona Mutesi, who is living in an impoverished township in Kampala, Uganda, when she discovers a chess club run by a missionary played by Oyelowo.
Nyong'o and Oyelowo are both expected at the premiere at the BFI London Film Festival on Sunday, as well as director Mira Nair and young star Madina Nalwanga.
Queen Of Katwe is released in UK cinemas on October 21.
