LONDON - Bob Marley's family hopes a new biographical movie about the superstar singer, who popularized reggae with his catchy tunes and spiritual and socially conscious lyrics, will help revive his legacy.

Bob Marley: One Love is produced by his wife Rita Marley and their children Ziggy and Cedella and executive produced by Brad Pitt. Directed by King Richard filmmaker Reinaldo Marcus Green, it sees British actors Kingsley Ben-Adir and Lashana Lynch taking on the challenge of bringing Bob and Rita Marley to life on the screen.

“(It was made) mainly to spread his message more, to put his message into a different medium; film, to reach another generation,” said Ziggy Marley as he attended the film's premiere in London on Tuesday.

The movie opens in Kingston in 1976, with Marley planning a peace concert in response to deep political divisions and violence

"One love is something positive out there in the world. That's what it's about, the message."

Marley, whose hits with The Wailers included No Woman, No Cry, Jamming and I Shot the Sheriff, was born in Jamaica in 1945. He died from cancer in 1981, aged 36.

The movie opens in Kingston in 1976, with Marley planning a peace concert in response to deep political divisions and violence. It sees the musician moving to London after both he and Rita survive an assassination attempt and recording the hit album Exodus. Flashbacks offer insight into Marley's childhood and youth.

Ben-Adir, who played Malcolm X in One Night in Miami and Barack Obama in The Comey Rule, prepared to play Marley while on the set of Barbie, in which he appeared as one of the Kens. Mastering Marley's mannerisms and language, the Jamaican patois, was not an easy feat, the actor, 37, said.

"All of it, the language, the music, finding Bob's true vulnerability. He was a tough man and he was a gentleman. There were so many colors to him,” he said.
