The film, which features a star-studded cast of Guy Pearce, Margaret Qualley and Josh Brolin, is set in the 2030s, where only those immune from a deadly flu remain alive.

It immediately draw parallels with the Covid pandemic with its aerial shots of abandoned cities and Hig’s constant search for resources like food and medicine.

Elordi, who received his first Oscar nomination earlier this year for Frankenstein, says “there were a few moments I remember looking around [on set] and thinking it’s strange to be doing this make-believe, when the reality is just behind us and just in front of us”.

He says a dystopian future like the one portrayed in the film is “frightening to think about” but “it’s something we have to examine and remember, because we are on the cusp of these realities”.

The 29-year-old also says he resonates with his character’s struggle to be content with life.

“Everything is sweet for us – we’re able to walk around on the street, go to the shops, go to the park, have dinner with each other and we still go to bed and think ‘What else is there?’, ‘What am I missing?’, ‘What’s wrong?’ and nothing is”.

This is also true for his co-star, Mare of Easttown and Memento star Pearce, who plays Pops, the survivor who meets Hig after emergency-landing his plane near his home.

Pearce says the way the film highlights “this world we take for granted” is “pertinent” adding: “You can go to the supermarket and get food and wake up with your family – a lot of people even to this day don’t live like that, so I am absolutely aware of [my] privilege”.
