The 50-year-old actress was honored at the Time 100 Gala in New York City on Tuesday, and stopped to chat with ET's Nischelle Turner about her powerhouse year and a particularly empowering on-set moment she recently shared with Reese Witherspoon.
“It was funny, we were in the car the other day shooting a scene, and there were some guys hanging out over the balcony, and they're like, 'Hey, come on up,’ and we were like, 'We're shooting our scene right now, you've gotta talk to our boss.’ And then Reese and I looked at each other and went, 'We are the boss!'” recalled Kidman, who, along with Witherspoon, also executive produces the HBO adaptation series, based on the Liane Moriarty novel of the same name.
“And that was like...I went 'Oh!'” she continued, with a laugh. “Then we looked at each other and went, not really, cause Andrea Arnold, who's directing, goes, 'Be quiet, get ready. Let's go, rolling.' We're still not the boss.”

Kidman won an Emmy and a Golden Globe for her role as the embattled Celeste Wright on the first season of the show, and filled her 2017 out with more acclaimed work, such as a starring turns in another lauded limited series, Jane Campion’s Top of the Lake, and celebrated features like The Killing of a Sacred Deer and The Beguiled. But she was hesitant to take too much credit for her stellar recent resume.
“Honestly, in the last year, I had the chance to work with four great directors. And as much as I would love to say, ‘Oh yeah, I did something different,’ I didn't,” she said. “I love what I do, I've always loved what I do. I just got very, very fortunate in the sense that four really, really talented directors -- Jean Marc Vallee, Jane Campion, Yorgos Lanthimos and Sofia Coppola -- all decided to work with me. That's kind of amazing. And I would love to say it was me, but I don't believe it is.”
Kidman walked the Time red carpet with her husband, Keith Urban, who had no trouble praising his talented wife for her deserved successes.
“I'm so proud of her. And it's so right too, she's got such a beautiful heart, and a collaborative spirit,” Urban gushed. “She's talking about these directors, but her collaborative spirit is so strong, that it's only right that these things have happened in a collaboration.”
For her part, Kidman noted that her celebrated career is made possible by “an enormous amount of support from my husband and from my children and my family.”
“But also there's times when roles connect and things come together and friendships that you've had for years suddenly result in work,” she added. “You're working together and you're putting that energy into something.”
Meanwhile at Cinemacon in Las Vegas on Tuesday night, Kidman's Big Little Lies co-star, Shailene Woodley, also chatted with ET's Kevin Frazier about season two of the show and working with Meryl Streep this time around.
"I mean, no big deal working with Meryl Streep," she bragged. "She is actually that good. That's what I want to say. The stories are real and what you see is real and she's the best there is."
Woodley, 26, added of Streep, "She is profoundly lovely."
