Kevin Macdonald, the Oscar-winning director, said he was inspired to make his documentary about reggae star Bob Marley while filming in Africa.
The film, called Marley, is the story of reggae's biggest star who died 30 years ago at the height of his fame.
Kevin told Screen Magazine: "When I was working on The Last King Of Scotland in Uganda, I remember going into the slums of Kampala and seeing flags with his face on and hearing reggae pumping out. Anywhere you go in the world Marley speaks to people."
The film, which will be previewed at the Cannes Film Festival, sees the director travel to Jamaica, India and the US to discover the story behind the star and includes an interview with reggae veteran Lee "Scratch" Perry.
Kevin won an Oscar in 2000 for his documentary One Day In September, about the murder by Palestinian terrorists of Israeli athletes at the 1972 Olympics.
He has enjoyed Hollywood success with climbing film Touching The Void and a remake of the television thriller State Of Play.
The Last King Of Scotland starred Forest Whitaker as brutal Ugandan dictator Idi Amin.
