Nicole Kidman refused to say "the N word" on the set of 'The Paperboy'.
The movie has proved controversial because of a scene where Nicole's character urinates on another, but when it came to making a racist remark, she outright refused.
Director Lee Daniels told UsMagazine.com: "I asked her to use the 'N' word.
"I could feel the racial tension there in the town. She said, 'I won't do it.' I told my producer, 'She won't do it!' Then he mapped it out - 'Lee, day one she is on a washing machine, day two she is urinating on Zac Efron, day three she's having telepathic sex... I think you can forgive her."
Nicole - who has four children; adopted Isabella, 19, and Connor, 17, with ex-husband Tom Cruise, and daughters Sunday Rose, four, and Faith Margaret, 21 months, with husband Keith Urban - plays a woman obsessed with marrying a death row inmate in 'The Paperboy' and she said it "didn't feel right" to use the racially-offensive word.
Of her refusal to make the requested remark, she explained: "I just didn't feel it was right for the character.
"I have a son [Connor] who is African American. I just didn't feel like it was right. What I try to do as an actor is fulfill a director's vision. I have opinions, but at the same time I'm not there to stop him from anything. I've really tried to do that in every film. I never want to pull them off their vision."
'The Paperboy' also stars Zac and Matthew McConaughey as brothers investigating the case of the inmate who Nicole's character is set on marrying.
