Nicole Kidman stuns on the cover of The Hollywood Reporter‘s Sundance issue.

The 45-year-old actress opened up on Scientology, urinating on film, and all things related to the movie industry. Here are excerpts from her interview:

On Scientology: “I’ve chosen not to speak publicly about Scientology. I have two children [adopted with Cruise] who are Scientologists – Connor [17] and Isabella [20] – and I utterly respect their beliefs.”

On what defines a ‘movie star’: “I actually don’t even know what a movie star is now – what is a movie star? When the best female part of the year is Claire Danes in Homeland, you know the game’s changed. Maybe in the ’50’s, there was a far more particular idea for a movie star. But now that’s all blurry – everything’s more fluid.”

On turning down big studio movies: “I come from Australia, I was trained in indie movies. It’s an unconscious decision — it’s who I am. As an actor, you live and die by your choices. I don’t associate with mainstream films anymore. I don’t do so well in them, either. I guess I have a foot in both worlds. I’ve been offered some studio films this year and turned them down. They just didn’t align with who I am.”

On urinating in The Paperboy: “I just don’t find urination shocking. I think I peed in the beginning of Eyes Wide Shut, too. But then, I don’t find a lot of things shocking! Violence is a lot more shocking than sex – sex is primal.”

On her relationship with directors: “I do develop very powerful relationships with most of my directors. Gus Van Sant changed my career with To Die For. I’ll definitely work with Lars von Trier again. And [The Hours director] Stephen Daldry is like a soulmate. He was so kind to me when I was pregnant, even when I couldn’t do The Reader.”
