Morgan says he wasn't scared to show Mandela the film, but he was concerned. "If he didn't like it, I didn't think he would say anything, but if he did like it, he wouldn't be able to hide it," Morgan says. "And he wasn't able to hide it."
At first, Morgan says Mandela was hard to read. "There's that sphinx thing about him," he says. "But when I came onscreen, he leaned over and said, 'I know that fellow.' So I took that to mean he recognized himself in me, and that was a big plus."
