Her latest is the drama "Birth," in which she plays Anna, a widow hoping to start a new life, but still grieving the loss of her husband 10 years after his death.
Suddenly, a 10-year-old boy enters the picture and tells her he is the reincarnation of her dead husband. Eventually, she believes him and falls in love all over again.
She discusses the role with The Early Show co-anchor Harry Smith.
He notes that, when "Birth" was shown at the Venice Film Festival, people were apparently booing and screaming at a scene in which the boy and Anna are in a bathtub together.
"That's what was so misrepresented," she tells Smith. "Before the movie, everyone was like, 'What is this? A movie about a 10-year-old boy and a woman?' And — when anyone sees the movie, they go, 'Huh?' Well … there isn't anything like that in it. It's almost like — the film is about love. It's not about sex. …I would never make a film that I thought compromised what I believe, and my integrity in terms of what I believe. And — in terms of children — I just wouldn't. It's doesn't interest me and I don't need to."
How could Anna have come to believe the boy's claim? "She needs this to happen," Kidman explains. "So that's why she believes it. I mean, she challenges it slightly, but basically everybody else in the family goes, 'You're insane.' And she goes, 'No, I know it's him.' Because she wants it to be him. Desperately wants it to be him."
Asked about Kidman having said she related on some level to Anna, Kidman chuckles and replies, "Yeah. …I'm in a position at the moment where I can choose to do certain films. And this, for reasons that are obviously very personal, I felt an enormous understanding for her.
"And the director (Jonathan Glazer) said to me, 'I wanna capture — you.' And that made me uncomfortable, because I thought, 'I know how to play Virginia Woolf, or I can go and sort of put on all of these things and hide behind them almost.' But when a director just states that very matter-of-factly, that makes you feel — 'I don't even know who I am. How the hell am I going to be able to give you me?' But he did that very gently and delicately. He sort of just put the camera there and captured my thoughts."
With a resume that includes an Oscar for "The Hours," and critically heralded roles in "Moulin Rouge," "To Die For" and "The Others", just to name a few, Kidman's roles are rarely merely ordinary.
But she was modest with Smith: "I just can't believe that I'm even in a position to be making movies, to be honest. There's times when I go, 'I can't believe somebody wants me to be in their movie.' So, whatever power I have (in the business) at the moment, I want to give to the directors that I believe in."
Kidman conceded she's insecure about her talent. "That's why I hardly ever see my own movies!"
Kidman is currently filming something completely different: a big screen version of the magical TV classic, "Bewitched," co-starring Will Ferrell.
