Nicole Kidman relied on husband Keith Urban to ‘bring back reality’ after filming The Undoing

Her gripping new psychological thriller, The Undoing, is just the latest in an endless list of harrowing projects she has starred in.

But Nicole Kidman, 53, has admitted that a lifetime of playing such intensely dark and layered characters have ‘taken a toll’ on her.

Speaking on Sunrise on Monday, the Oscar winner expressed that she relied on her ‘nurturing’ husband Keith Urban and their children Sunday, 12, and Faith, 9, to help ‘bring her back to reality’ after an emotionally ‘taxing’ day on set.

Speaking about her friendship with co-star Hugh Grant on the set of the Susanne Bier directed limited series, The Undoing, the star explained that they shared a lot of laughs together.

‘You’ve got to have laughs when you’re doing stuff like this. Otherwise, it’s just too harrowing.’

Host Edwina Bartholomew asked: ‘How do you shake off these characters at the end of a long day and return to your own life?’ 

Nicole responded: ‘It’s taken it’s toll. I almost work from a deeper place now and thus it’s very taxing at times.’

The star explained that she was accompanied by her ‘nurturing’ family to New York where she was shooting, The Undoing. 

‘My family was with me, and just to have my little girls, and Keith, and have dinner with them brings immediate reality back. Suddenly the boundaries get set.’

Nicole added: ‘It doesn’t mean that I’m not thinking about it [work]. That’s always going through my brain, I’m preparing for the next day, and a lot of times I’m having to learn huge amounts of dialogue. 

‘But at the same time it’s just having that place where I can breathe and feel me. And Keith provides an enormous amount of that and hopefully we provide that for him when he’s on tour because that’s the benefit of having a family that’s tight .’ 

The Big Little Lies star has been happily married to country singer Keith since 2006 

Nicole will next be starring alongside Hugh in the drama The Undoing, which reunites the actress with her Big Little Lies creator David E. Kelley.

The Undoing, which is based on the 2014 novel You Should Have Known by Jean Hanff Korelitz, follows Grace (Kidman) and Jonathan Fraser (Grant), who are living the only lives they ever wanted for themselves.

Their peaceful world comes crashing down with a violent death and a chain of terrible revelations.

Left behind in the wake of a spreading and very public disaster and horrified by the ways in which she has failed to heed her own advice, Grace must dismantle one life and create another for her child and her family.

The Undoing will be available to stream in Australia on Binge from October 26, 2020
