The 56-year-old actress played Celeste Wright on the hit series - which ran for 14 episodes over two seasons between 2017 and 2019 - and she admitted there was a moment where the gruelling realities of working on set bubbled over.

Speaking in a roundtable chat with Jodie Foster, Brie Larson, Naomi Watts, Jennifer Aniston, Sofia Vergara and Ana Sawai for The Hollywood Reporter, she recalled: "I threw a rock because [the door] was locked and I couldn’t get in.

“I’d never done that in my life. I obviously [had a lot] pent up. I broke the whole thing. It cost a fortune."

Nicole - who has teased plans for a third season - insisted given the long stints actors face on set, there "really isn't the time" to focus on self care.

She remembered telling co-star Alexander Skarsgard and season one director Jean-Marc Vallee - who died of a heart attack aged 58 in December 2021 - about what she did.

She added: "And then I went back the next day and I said to Alexander [Skarsgard] and Jean-Marc [Vallée], ‘I threw a rock through the window,’ and they were like, ‘Whoa …’ I said, 'I was kind of p***** off'.

“But there’s a way in which we operate where the show must go on, and so you just keep going — you show up and you do it and do it and do it and do it.

"And a lot of times, it’s six months of 12, 14-hour days and there really isn’t the time to go, ‘I need to take care of myself.’ ”

However, it wasn't the only show that took its toll on her mental health, and it has even prompted her own career choices.

She explained: "After 'Expats', I went and did a comedy because I went crazy with my own psychology. I was like, ‘This is unhealthy'.

"And it’s something that I think we need to talk about as actors — protecting your body so that you can live for as long as you are given on this earth. Because it’s very tough on the psyche.”

Nicole agreed with Sofia that "the body doesn't know that what you're going through" isn't real, which amplifies the need for looking after yourself.

She said: "The idea of being able to go and get a massage or a hot bath or even a pat on the back, just someone touching you and going, ‘It’s OK.’ ”
