The Aussie actor said she tended to ignore her dad's efforts at giving advice when she was younger. The views of mother Janelle were more important to her and sister Antonia.
"Dad's a psychiatrist, and when I was younger he was always trying to give me advice that I wouldn't listen to," Kidman told the Daily Mail. "Now that I'm older, I really value his insight. When I was younger, I always felt closer to my mother.
"It wasn't until I was older that I really realised how special my father is, too."
That came when she and Cruise split after 11 years of marriage in February, 2001.
"When my marriage fell apart, I needed to reach out to my dad. He was wonderful," she said. "He stood by me, comforted me; showed me, at a time when I really needed to see it, the way a man can be strong, dignified and loving.
"I'm very grateful that I had such a good father, to see me through that time, because it put me in good stead for trusting again the next time I fell in love."
