Nicole Kidman has said she has no idea why people were shocked by her peeing scene in The Paperboy.
The actress urinates over Zac Efron in the film, which caused a stir at the Cannes film festival last summer, after his character is stung by a jellyfish.
But Nicole told The Hollywood Reporter: "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!"
She said she'd seen a lot more offensive things in films over the years - and that she also has no problem with sex scenes.
"Violence is a lot more shocking than sex ... sex is primal," she said.
Nicole said her heart was in independent films and that she could no longer say what a movie star is.
"My heart is independent... 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 any more. I don't do so well in them, either. I guess I have a foot in both worlds," she said.
"I actually don't even know what a movie star is now ... what is a movie star?" she added. "When the best female part of the year is Claire Danes in Homeland, you know the game's changed."
Nicole praised her Paperboy director Lee Daniels, saying: "Lee had an obsession about shooting me from behind... he was obsessed with my ass! To me, that was so funny. He's hilarious... I felt shy singing in Moulin Rouge! But peeing ... no, not shy."
