Upon accepting the award, Ejiofor paid a special tribute to the film's director Steve McQueen.
"You really brought us all through it," he said. "You had the real vision to tell this remarkable story. The extraordinary life that he had, and to tell this story in a way to make it of such value, of such worth to all who were there. Thank you for this, it was yours. I'm going to keep it, but it's yours."
