"Duck Dynasty" star Phil Robertson served as a narrator and tour guide in the new film "Torchbearer," which will be screened at the Cannes Film Festival next month.

"Torchbearer," directed by Stephen K. Bannon, explores the negative effects in society when Western civilisations continue to push God away.

"If you look around, the frustration you see coming out of America, in my opinion, is primarily being fueled by the depravity [that] has become mainstream," Robertson tells Breitbart News. "Murder is mainstream; we slaughter our own children. We priss around and parade our perversion; it's being done in front of our very eyes. Depravity, literally. And I never thought I'd see it in my lifetime. But it has literally become mainstream."

Robertson strongly believes that if people violate the liberties that God has freely given them, then His wrath will definitely come. Right now, people are "swimming in a sea of depravity," and he hopes that "Torchbearer" will serve as a wake-up call for them to seek God and ask for forgiveness.

"It's impossible to govern the world without God and the Bible. So here we are, so I think maybe hopefully, through this movie, this documentary, we'll change the hearts of some people. That's my goal," he says.

To make the film, Robertson and the rest of the cast and crew travelled to the Coliseum in Rome, visited French Revolution sites in Paris, and walked through the beaches of Normandy and the Auschwitz concentration camp in Poland.

Seeing all those historic places made Robertson develop a lump on his throat. "Well, it was eerily breathtaking," he says. "I'm a guy, I guess being in my emotional make-up, I don't shed many tears over anything actually. But in the making of this film, when I was in those places that you just mentioned — Auschwitz, and where the French Revolution took place, and those ruins where I thought about the Romans and how they slaughtered our brothers and sisters on a scale of what ISIS is currently doing — and I'm telling you the truth that it was actually overwhelming."

Given the current state Western civilisation is in, one might think that there is no more hope to turn back to God. But Robertson is optimistic that it can still happen. "I think there is hope, because the great thing that God has allowed for human beings is, we do and we can repent of our wickedness and turn to Him," he says.
