From the trailer you can see bits of footage connected with NZ, like a snippet of Dylan Taite's interview with Marley, and a shot of Marley walking out onstage at Western Springs in 1979.
From TV3 News... "the Jamaican singer died of cancer in 1981.
He kept his illness to himself until it was too late, and of the ninety people interviewed for the film, [director Kevin] MacDonald still couldn't find out why.
“I'd like to know did he know he was ill before the end of his life? I think he did, I just think he didn't tell anyone, but certainly no one around him knew that he was ill.”
“My life is only important if I can help plenty people. My life isn’t for my own security, my life is for people,” Marley says in the film.
