Imagine a world where premarital sex is only legal for one night out of the whole year (and, yes, condoms are mandatory). It might seem preposterous, but it is the premise of the movie One Night Only, a hilarious rom-com that takes us up, down, and all around New York City—crucially, all in just one night. Allie (Monica Babaro) and Owen (Callum Turner) give us a whistlestop tour of New York City as they keep bumping into each other while separately seeking to get laid. “Most importantly, I like filming parts of New York that you don't really see in movies,” he told Condé Nast Traveler. Gluck spoke to Traveler about all the neighborhoods and locales, both planned and those discovered along the way, that made their way into One Night Only.
