The Rastafarian movement, known for its dreadlocks and association with the hypnotic sounds of reggae music, has the ability break down religion, colour, and language barriers, says the granddaughter of reggae's greatest performer.

Donisha Prendergast, the granddaughter of reggae pioneer Bob Marley and his wife Rita, travelled the world to document the history of the movement whose religious and political overtones began in the slums of Jamaica.

Prendergast is featured in "Rasta - A soul's journey," which delves into the origins of the Rastafarian movement in Jamaica and around the world.

"Travelling around the world, what I found is that Rastafari has the ability to break all barriers," she said.

Prendergast travelled to eight countries to study how the movement evolved internationally from the coronation of Ras Tafari Makonen, also known as Haile Selassie, to the streets of Jamaica, which has adopted the movement over the decades.

But Prendergast was surprised to find a large group of Rastafarians in Israel.

"Israel was very interesting for me because Israel had the most reggae music out of all the places I've been to including Jamaica," she said.

The movie will be screened at the Royal Ontario Museum for Black History Month. The ROM will also host African Caribbean Cultural Heritage Day celebrations on Feb. 25.
