“Bob Marley: One Love” is a new biopic about Bob Marley in the late ‘70s — a time when Jamaica was in political turmoil and Bob was conflicted about the direction of his music. Director Reinaldo Marcus Green (King Richard, Joe Bell) is no stranger to dramatizing the stories of real-life people. He tells Tom what a feature film brings to Bob’s story that a documentary could never do, why he casted a non-Jamaican and non-musician to play Bob, and how being a high-level baseball pitcher set him up as a filmmaker.
