Beasts of No Nation, a film about civil war in an unnamed West African country, had just had its UK premiere at the BFI London Film Festival.
The movie, written and directed by Cary Fukunaga, is based on a novel by Nigerian-American writer Uzodinma Iweala and takes its title from an album by Fela Kuti.
It features British actor Idris Elba in the role of a warlord who trains an orphan as a child soldier, played by a 14-year-old first-time actor from Ghana, Abraham Attah.
Last month, Attah won the Marcello Mastroianni's Best Young Actor Award at the Venice Film Festival.
“I don’t know anything about child soldiers so when I got the role I had to do some small research about the war,” he told BBC Africa’s Frenny Jowi.
“I was having an acting coach. I didn’t feel that emotional. It was just natural. I don’t know what I was doing but I read the script and I understood what I was going to do on the set,” he added.
