Half of a Yellow Sun, a much-praised and well-loved novel written by Nigeria's Chimamanda Ngozi Adichie, tells the story of two sisters during the Biafran War in the 1960s.

Playwright Biyi Bandele adapted the book into a movie for his directing debut and the film premiered at this year's Toronto International Film Festival.

Chiwetel Ejiofor co-stars alongside Thandie Newton.

BBC Africa's Komla Dumor met the director and asked him about the challenges of turning one of the continent's most beloved books into a film.
