Ever since the official trailer dropped for the Callum Turner–Monica Barbaro rom-com One Night Only, quickly racking up millions of views on its way to its nearly 40 million total, internet commentators have had a lot of questions about the film’s central premise in which premarital sex is illegal apart from one 12-hour period a year.
How is this law enforced? Are people breaking the law? How did this legislation pass? What counts as “sex” under this new mandate? Are marriage (and divorce) rates skyrocketing? What about affairs?
Rest assured: Some of those questions are answered in the movie, and explanations are starting to trickle out online for those unconcerned about spoilers. Beyond that, One Night Only writer, Travis Braun, who saw his screenplay top the 2024 Black List, has answers, but they’re not all in the Will Gluck-directed Universal movie now in theaters.
“I set out to write a movie about the circus that is modern dating, and I thought how fun if we could set that all in one night, and I have answers to those questions, and some of them are in the movie,” Braun told The Hollywood Reporter at the One Night Only premiere earlier this week in New York.
Braun said he definitely thought about the specific rules of the film’s alternate reality, framed as three years on from the no-sex act being passed, but didn’t want to get too deep into the politics of the world of the movie.
“There’s a big mythology that I’ve built out and then as you develop a movie you start to pare down and you go: What does an audience really care about, and what are they showing up to see? For me the answer is always a love story, romance,” he told THR. “I hope they can come in and we’ll show them how this world functions, and then they can just enjoy the movie and have fun. The whole focus of this was love story and romance first, and the world-building obviously has to make sense and has to be there, but ultimately we weren’t interested in getting into the politics of it. We wanted to tell a story about these two incredible people trying to find love on this crazy night.”
Producer Jacqueline Monetta, who brought Braun’s script to Gluck, said they didn’t want moviegoers to have all of the answers.
“I had a million questions. I was like, ‘What does this mean? What does this world look like? How do people communicate? What’s different?’ And that’s I think what’s so smart about it,” she said of One Night Only‘s “big idea, high-concept” premise. “We don’t answer every question in the movie, purposefully, because we want those questions to be had on the car ride home. We want people to keep talking about it and really think about what would this mean for our world, what does it mean for our world now. But I think Will and I were really specific on what questions we wanted to answer.”
In a recent Reddit AMA, Gluck also detailed how he and his team approached the world building of the movie while not wanting it to be all about the mandate and offered prospective moviegoers hints for where to find the answers to their questions.
“We spent a lot of time talking about the rules of the world, and if you’ve seen the movie, or when you see the movie, you’ll see that the rules of the world and the world building are all in the background,” he said. “It’s on TVs, signage, in thrown-away lines, because we didn’t want to give the world short shrift, but we didn’t want the movie to be about that. It’s another way I want people to see this. If they see it more than once, they’ll pick up so many more rules of the world in the background. A lot of the questions that I’ve been getting after people have seen the movie are actually answered in the movie, which is by design because I want people maybe not to know them. So, yes, it was a tricky tightrope to have them there, but not for the movie to be about it.”
Turner meanwhile echoes Braun’s advice for curious prospective moviegoers: “Go see the film!”
“You’ll realize pretty quickly what the realm is that you’re working within and it’s a comedy,” Turner says of what inquisitive filmgoers will find. “There are no great political undertones, I don’t think. This is just a place where you can escape for an hour and a half, two hours and enjoy and laugh your head off.”
