Sir Anthony Hopkins believes in God.

The screen legend stars in new supernatural thriller 'The Rite' - in which he plays Father Lucas, a Catholic priest who specialises in exorcisms - and he admits the role made him evaluate his own beliefs about religion.

When asked if he believes in God by Piers Morgan on his CNN talk show, he said: "Yes, I do. I'm not an atheist. I don't know what it is. None of us do.

"But everything is God. Everything is particle physics. I've read everything I can. I started reading Charles Darwin's 'The Origin of the Species' . I believe in a God that Einstein believed in, a sort of Spinoza kind of interpretation."

Although he believes in the concept of a creator, Anthony doesn't agree with the dogma imposed by organised religions.

Instead, the 73-year-old star believes fundamental certainty in life can cause much misery.

Discussing the absolute beliefs of organised religions, he said: "I think it is dangerous. Certainty is responsible for some of the most awful terrors in the world.

"I made a point in the film ('The Rite'), I was saying to the young priest, 'So what do you believe in? The truth? Oh, yes, the truth. Look where that got us. Hitler, Stalin - they know the truth.'

"I know atheists, brilliant atheists. I enjoy reading Christopher Hitchens, I'll examine everything. But, what I enjoy is uncertainty.

"There's lines in this movie where I say, 'Cherish your doubts because there God is hiding.' I don't know. You don't know. None of us know.
