'Crazy' pressure of bringing Bob Marley to big screen

When you're making a film about someone as universally loved as Bob Marley, the weight of responsibility hangs heavy.

With "Bob Marley: One Love" hitting cinemas around the world next week, director Reinaldo Marcus Green admitted he hesitated about taking on the biopic of the reggae legend, a project that has previously defeated both Martin Scorsese and Oliver Stone.

"The responsibility was so large that I thought it was crazy to do this," said Green, whose previous film was "King Richard," starring Will Smith as the father of tennis stars Venus and Serena Williams.

"But we had our world premier in Jamaica and that was a huge sigh of relief," he told AFP.

"The Jamaican people are hard - they are like, 'Don't mess with Bob!' - but luckily they gave us the seal of approval."

The film focuses on a particularly rich creative period between 1976 and 1978 when Marley released the album "Exodus" that made him a global star, but also suffered an attempted assassination and discovered the cancer that would soon after claim his life at just 36.

It was co-produced by his widow Rita Marley and their children Ziggy and Cedella as well as a certain Brad Pitt.

It was Ziggy who approved British actor Kingsley Ben-Adir to play his father.

Ben-Adir has already played two other towering historical figures: Malcolm X (in 'One Night in Miami') and Barack Obama ('The Comey Rule').

But this has been another level for the 37-year-old actor, with his face on billboards all over the planet.

"It's not my face I see on those posters. It's the good will and the love that Bob has around the world," he told AFP. "Bob has this power."
