Shia LaBeouf found God on the set of new war movie Fury and credits co-star Brad Pitt and director David Ayer with helping him achieve a new level of spirituality.

The actor is trying to get his life back on track following a series of bizarre incidents and alcohol-fuelled bar fights and legal issues, and he insists his new-found love of religion will help him get past his troubles.

In a new Interview magazine expose, the Transformers star calls himself a "Christian man", insisting he's serious about being a man of God.

He says, "Not in a f**king bulls**t way, in a very real way. I could have just said the prayers that were on the page. But it was a real thing that really saved me. And you can't identify (it) unless you're really going through it. It's a full-blown exchange of heart, a surrender of control. And while there's beauty to that, acting is all about control. So that was a wild thing to navigate.

"I had good people around me (on the set) who helped me. Brad was really instrumental in guiding my head through this. Brad comes from a hyper-religious, very deeply Christian, Bible Belt life, and he rejected it and moved toward an unnamed spirituality. He looked at religion like the people's opium, almost like a Marxist view on religion.

"Whereas David is a full subscriber to Christianity. But these two diametrically opposed positions both lead to the same spot, and I really looked up to both men. It was nice to have conversations with Brad about the family he came from and what he was using to get through the day."
