Callum Turner’s wild new rom-com compared to The Purge – but for sex

Callum Turner has another movie on the horizon alongside persistent rumours that he’ll be slipping on James Bond’s tux (whenever that actually might be) – and it’s quite an eyebrow-raising prospect.

Coming in hot behind news of Taron Egerton’s upcoming comedy-thriller Everybody Wants to F**k me, in which every woman is stalking him and does indeed want to have sex with him, comes One Night Only.

In this film, Rose of Nevada actor Turner stars opposite Oscar nominee Monica Barbaro as a pair of strangers who end up together on their least favourite night of the year, which is the only night that pre-marital sex is allowed.

In their world, pre-marital sex is otherwise outlawed, in a long-standing rule that nobody remembers being put in place.

But for this specific time period, from 7pm to 7am the following morning, single people are allowed to sleep together.

Links have been drawn between this premise and that of 2013 action horror film The Purge, starring Ethan Hawke and Lena Headey, where there’s one day a year when all crime is legal – including murder.

However, writer-director Will Gluck is hesitant to wholeheartedly embrace the comparison.

‘It’s less about the act of having sex and more about the pursuit of it,’ he told EW. ‘So I guess if you were gonna make this analogous to The Purge, it would be like spending 12 hours deciding who to murder, as opposed to committing the murder [itself].’

A fair point but also still a rather high-pressure situation, with just hours to potentially find the person you want to spend the rest of your life with (or at least, are stuck on enough to marry).

Gluck also says he ‘steers away’ a little from talk of The Purge because ‘you’re not gonna be seeing orgies and nudity everywhere. That’s not the movie’.

Instead, Allie (A Complete Unknown’s Barbaro) and Owen (Turner) end up together after wandering New York’s streets alone, two ‘lost souls’ who’ve both been ghosted on this most notable of nights: Allie, by her best friend who has hooked up with a stranger, and Owen by his girlfriend, who decides she wants to spend her one night of pre-marital sex with someone else.

And this, brutally, is just as Owen was about to propose.

Barbaro acknowledges the ‘kind of crazy premise’ of One Night Only – but reckons it’s not that far from the realities and pressures of modern-day dating.

‘It’s kind of an allegory for dating and how intense it can be when you’re seeking true connection with somebody. I feel like it’s deeply relatable. It’s just supercharged in this one-night premise,’ she told the publication.

Turner is coming off the back of another strong rom-com, Eternity with Elizabeth Olsen and Miles Teller, and enjoys the genre trope that Owen and Allie keep being forced together, even though they don’t want to be.

‘The universe [is] banging both of them over the head by putting them together over and over and over again on this one crazy night that they both hate,’ Turner says, comparing it to a cosmic joke.

The movie’s cast is also set to include ’80s rom-com queen Molly Ringwald, Maya Hawke, Julia Fox, Este Haim and LeVar Burton.

One Night Only is scheduled for US release on August 7, 2026. It is yet to receive a UK release date.
