[4] The film initially began development in 2008, with a planned release date for Marley's 65th birthday on 6 February 2010.

Although Marley was enthusiastic about music from a very young age, he had disappointing record sales as a solo artist with his first singles, “Judge Not” and “One Cup of Coffee”.

The group made Bob Marley a household name and brought worldwide attention to Jamaican culture, Reggae music and the Rastafari movement.

Marley firmly states several times that he is a key part of the Rastafari movement: the belief that the Emperor of Ethiopia, Haile Selassie I, is the reincarnation of Christ.

Rita Marley stated that she also converted to Rastafari upon the visit of Selassie I to Jamaica when she saw “marks in his hands”, similar to those Jesus bore when he was nailed to the cross.

Marley's love of Rastafari was brought out in lyrics of songs such as, “Exodus” and “Jah Live”.

Throughout Marley's life, he had a total of eleven children with seven women, despite being married from a young age.

Contrary to those sources, Rita Marley is quoted in saying: "Somebody stepped on it with their spiked boots and it started to get infested.

The documentary also conducts interviews with Rastafari doctors, which shows Marley's strict adherence to the religion.

Rastafari doctor, Carleton Fraser, states that “doctors recommended amputation of the hip and removing the entire leg.” Chris Blackwell gives conflicting information and insists that they just needed to amputate Marley's big toe for him to survive.
