The actress, who is seen in an infamous urination scene where her character has to take the bite out of Zac Efron's jellyfish sting in 'The Paperboy', said she was not uncomfortable in the act, said 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! Violence is a lot more shocking than sex – sex is primal," said Kidman.
The Lee Daniels-directed movie is based on Pete Dexter's 1994 novel about reporters in the '60s trying to spring a convict from jail.
"Lee had an obsession about shooting me from behind... To me, that was so funny. He's hilarious, I love him. I'm drawn to Lee for his wild nature. I felt shy singing in Moulin Rouge! But peeing -- no, not shy," she added.
