Nicole Kidman
is opening up about shooting some of her intense scenes in Big Little Lies, and how she fell back on the love and support of her husband, Keith Urban, when dealing with the emotionally draining aspects of filming the series.

The Oscar-winning actress spoke with ET's Lauren Zima at HBO's Big Little Lies FYC event at the DGA Theater in Los Angeles on Tuesday, where she reflected on some of the difficult scenes she shared with co-star Alexander Skarsgård.

"Because we were shooting for so long… I think the duration of [the production] slowly started to seep in," Kidman said, referring to the lengthy shooting schedule of a TV series, as compared to a film, and the number of scenes that called for emotionally challenging interactions.

"Normally I can step back into my family life in a very easy way. I mean, not always, but you know, usually. I've been working a long time now," she explained. "But it was hard."

In the series, Kidman stars as Celeste Wright, wife of Skarsgård's Perry Wright, and while the two project an image of a perfect husband and wife dynamic in front of their friends, they actually have a bitter and violently abusive relationship behind closed doors.

According to Kidman, when she would leave the set after a difficult shoot she always "came home to loving arms" at home with Urban and their daughters: Sunday, 9, and Faith, 6.

"Luckily I have a partner who is artistic so he understands what it takes to support that," she told. "[He] would hold me, and I was really upset at times. Really damaged and really upset and physically and emotionally drained and in pain... Luckily I have that at home and I also have people I can talk to and get it out."

However, despite the toll the series took on her psyche, Kidman said she'd love to come back for a second season of the series, and work alongside her cast of talented co-stars, including Reese Witherspoon, Shailene Woodley, Zoe Kravitz and Laura Dern.

"We love working together and watching Laura and Reese and Shai and Zoe and all of them do their thing," she said. "We all knew it was special when we were doing it, but for it to be embraced in this way is also spectacular. Would we want to work together again? Absolutely. Would we explore options for that to happen? Absolutely."

The show and its cast have certainly been embraced by critics and viewers alike. When Emmy nominations were announced earlier this month, the show walked away with an Outstanding Limited Series nomination. Additionally, Kidman and Witherspoon are both up for the Outstanding Lead Actress Emmys, while Dern and Woodley were nominated for Outstanding Supporting Actress.

Kidman said the entire cast and crew couldn't be more excited, sharing, "We're just reveling in [the fact that] that everyone got nominated. That just doesn't happen, you know? I've been in so many different shows and had a number of experiences over the years and this is completely new."

"For the whole production to have been embraced and the performers, it's very unusual and we're really in a very special place with this," she added.

If the cast did reunite for some version of a second season, the actress says she would want the show to "continue on with the complexity and with the truth" that made the first season so great, along with the same fearlessness when it comes to "entering into the female psyche."

Recently, ET caught up with the cast of Big Little Lies to give them a little quiz on how much they really know about one another. Check out the video below to see the stars put their friendships to the test.
