A Look Behind Andrew Scott and Paul Mescal in 'All of Us Strangers'

The highly anticipated "All of Us Strangers," starring Paul Mescal and Andrew Scott, is almost here, and filmmaker Andrew Haigh is giving a peek behind the production.

In an interview with Vanity Fair, Haigh shared that he hosted the film's production crew in his childhood home and gave a tour of his vision before the film.

"The plan was to redecorate the interior to resemble its old self," Vanity Fair reports. "In function, this was no longer just a distant family artifact. The modest home in a small London suburb just outside of Croydon was about to become the most significant location in Haigh's new film – a childhood home doubling as a portal to the past."

Loosely adapted from Taichi Yamada's Japan-set 1987 novel "Strangers," Haigh's film adaptation marks his most expansive vision yet.

"To suddenly deal with my own past at the same time as I was telling a story about someone else dealing with their past – I'm not sure if it was foolish, emotionally or mentally," Haigh told Vanity Fair. "But it was a really strangely cathartic experiment."

An experiment that audiences will see on screen. The film follows a 40-something writer Adam (Scott), who lives alone in a high-rise outside of London. When his neighbor, Harry (Mescal), drunkenly flirts with him, it turns into a tender relationship.

Adam then finds himself back into his hometown, in a house left behind by his family. In that house, he counters his parents, who previously died in a tragic accident, and here is where a meeting of the living and dead help Adam confront his past.

"It's an opportunity to revisit your parents long after they might have passed and to have a dialogue," said Oscar nominee Graham Broadbent ("The Banshees of Inisherin"), who, alongside producing partner Sarah Harvey, first brought Haigh the book to adapt. "What would you tell your parents about your life if you were an adult and they were no longer with us?"

The question drives the movie forward for Haigh.

"I wanted it to all feel very integrated, like our memories do and like how we go through life – the pain we carry around is always just there, hidden, and it can come up and feel incredibly real," he said. "It was always about that feeling when you're just about to fall asleep or you just wake up from a dream – when everything feels a little bit strange."

Haigh wouldn't call "All of Us Strangers" a ghost story but more a story about being brought into someone's mind.

"I make no bones about the fact that this is a specific experience I'm telling, of a man in his late 40s who's gay," said Haigh. "I'm trying to tell something that I understand, that is my experience of the world, and that is authentic to me."
