Tune in to catch Nine Perfect Strangers and you’ll find drama and suspense. But you might also see some heady stuff, says star Nicole Kidman. “It kind of delves into some of the biggest existentialist questions,” she says. “What is reality? What place can you choose to exist in? Can we alter that? Is there another reality that we can access that maybe is a more desired reality?” The Hulu limited series that starts this week is definitely ambitious, centring on nine troubled people attending a remote Northern California wellness retreat. Kidman plays Masha, the spa’s mysterious guru, who has an unusual treatment method involving psychedelics. The strangers include an unhappy romance writer, a former football star, a bored couple, a simmering-with-anger divorcee, a mysterious gay man and three members of a family grieving the loss of a fourth. Their 10-day retreat is told over eight episodes – like an Agatha Christie-style parlour mystery mashed with an adult The Breakfast Club . The series is adapted by David E. Kelley and John-Henry Butterworth from Liane Moriarty’s 2018 novel of the same name. The show’s cast is impressive, with Melissa McCarthy, Bobby Cannavale, Regina Hall, Samara Weaving and Michael Shannon in the ensemble. “I loved that there were so many characters in it that I felt were so truly three-dimensional,” says McCarthy, who plays the novelist. “They were complicated, and people are messy. And I thought that’s how real people are. I don’t know any perfect people. I wouldn’t know how to play someone perfect.” Things to know about Nicole Kidman’s Hong Kong-set series Expats Among the issues the series deals with are addiction, the warping influence of social media, emotional suppression, impostor syndrome and the complicated nuances of mourning. The nine visitors – as well as the spa staff, including Masha – are hurting in some way. “What would you do to take away the pain? How far would you go?” asks Kidman. “Those questions are really interesting to me, particularly when they’re put in an entertaining format.” Cannavale, who plays the former football star, read the script after having just finished Michael Pollan’s 2018 book How to Change Your Mind , which explores the therapeutic potential of psychedelics. The actor jumped at the chance to show another way to treat depression. “We’ve been treating people the same way for years. And we’ve been kind of ignoring this alternative way of treating it,” he says. “Maybe people who have never heard of this go, ‘Is that real?’ And they’ll do a little dive on their phone and go, ‘Oh, my God, it is real.’” McCarthy and Hall, who plays the repressed divorcee, were both attracted to the show’s message of appreciating the messiness of life and piercing through peoples’ over-processed, manufactured and edited portraits on social media. “I think once you recognise the flaw in someone else, you can see the flaw in yourself and that flaw can become beautiful,” says Hall. “As soon as you can see the beauty in someone else’s flaw, then you don’t have to look at yours so badly.” The series arrives at an opportune time to be talking about mental health, with the lockdowns for the pandemic making depression and isolation a cultural issue, as well as the Olympics bringing mental wellness to the fore. “I think that the last year and a half have given us wonderful opportunities of reflection and to actually sit with what we have been doing,” says Hall. “In that pause, it’s allowed people to say ‘It’s OK for me to be honest. It’s OK to not be OK.’ Not only is it OK to not be OK, it’s OK to say I’m not OK.” While the show is set in a remote part of California, filming took place in the southeastern Australian coastal town of Byron Bay, this “magic bubble where there was no Covid-19”, said McCarthy. The Australians took Covid-19 safety very seriously, giving the cast and their loved ones a military escort to their hotel rooms and quarantining them for 15 days with a guard outside. Masks and tests continued on set. “They were not kidding around. Their protocols were intense,” said McCarthy, who travelled with her family. “There’s nobody to clean your room. Nobody changed your sheets. You were just there and had some self-reflection. We did a lot of colouring, strangely.” Like what you read? Follow SCMP Lifestyle on Facebook , Twitter and Instagram .
