Documentary film: Who was the real Bob Marley?

Director Kevin Macdonald speaks about giving audiences a chance to find out who the 'real' Bob Marley was in his new documentary film, 'Marley.' "The way to understand Bob is as the first Third World superstar," the director says. "He is the only giant, not just of music but of the arts in general, who is recognised around the world, but who comes from the Third World. The fact that he grew up in a one-room hut and slept on a dirt floor is key to who he is and what his appeal is."
