Nicole Kidman is known for completely immersing herself in the characters she plays, but her latest project, “The Undoing”, really took a toll on her physical and mental health.
The Oscar winner, 53, admitted to playing Grace, whose husband is on trial for murder, in the HBO drama created a “turmoil” for her personality.
“Suddenly I was in this place. There was a kind of unrest over my personality where I was restless and there was compulsion over who I was,” Kidman explained in an episode of the podcast “WTF With Marc Maron.”
“I actually got really sick [in the middle of filming]”she revealed.”

The “Big Little Lies” star added how she tried to keep her work separate from her family life but could not develop “a technique to tell my brain and my body: ‘Oh, it’s just acting.'”
“I have not learned to clean it. It does not really work for me,” she described. “I’m going home and I’m not sleeping well and I’m not feeling well … It’s so disturbing to me.”
Kidman said earlier that her husband, Keith Urban, and daughters, Sunday, 12, and Faith, 9, “helped bring her back to reality” while playing Grace, who was “very taxing.”

“You’ll have to laugh when you do things like this. Otherwise, it’s just too shocking,” Emmy winner told Australia morning show “Sunrise”. “I work almost from a deeper place now, and that’s why there’s a lot of taxation at times.”
Fortunately, Kidman said her family was able to live in New York with her while she worked.
“My family was with me, and just having my little girls and Keith and having dinner with them brings instant reality back. Suddenly the boundaries are set,” she described.

Kidman called being with the family “the place where I can breathe and feel.”
“Keith delivers a tremendous amount of it, and hopefully we deliver it to him when he’s on tour, because that’s the benefit of having a close family,” she said.
