When you ask Donisha Prendergast, reggae legend Bob Marley's granddaughter, about the stories or faint memories she has of him (he died when she was three years old), she says, "You know, wherever in the world I am I know he is there with me. It's a strange thing, but in random moments, he will present himself as an image on a wall or on a shirt. Or someone will pass by playing one of his songs. And then I know everything is alright."

No wonder then that in 2011, the 34-year-old filmmaker made the RasTa: A Soul's Journey, which aimed to educate audiences on the roots and evolution of Rastafari (of which her granddad was a practitioner) - quelling the many misunderstandings and misconceptions about this way of life. She travelled to the United States, United Kingdom, South Africa, India, Israel, Canada and Jamaica - to explore the roots, evolution and impact of Rastafari.
