Des Hommes et Des Dieux depicts the assination of seven monks in Algeria in the mid-90s.
And it was a huge surprise box office hit in France, selling over 3 million tickets.
The film opened on Friday here in Quebec, and for the occasion, one of the people who helped make it visited cities around the province.
Henry Quinson lived in a monastary for almost six years after quitting his job as a financial trader. Following his time at the monastery, he spent more than a decade living in a poor, mostly Muslim neighbourhood in Marseilles.
He acted as the "monastic advisor" for Des Hommes et Des Dieux, ensuring that the film accurately portrayed monastic life.
