Faith and films have been lifelong obsessions for director Martin Scorsese, obsessions that he said have given him moments of peace amid turmoil, but also challenges and frustrations that, in hindsight, he will accept as lessons in humility.

"For me, the stories have always been about how we should live who we are, and have a lot to do with love, trust and betrayal," he said, explaining that those themes have been with him since his boyhood spent in the rambunctious tenements of New York and in the peace of the city's St Patrick's Old Cathedral, where he was an altar server.
