The actress still can't understand why the Lars Von Trier film left her so emotional.
Kidman tells the new issue of Entertainment Weekly, "I saw that film and I was supposed to go out to dinner afterward. I had to cancel dinner.
"I went home, got into bed, curled up in a ball, and cried. I don't know why I had such a profound, deep reaction to that film, but I did.
"It disturbed my spirit."
