Writer/director Caroline Vignal conceived the movie after talking to a friend she hadn't seen in months: after a difficult divorce and post-divorce phase, the friend, on someone else's advice, tried a dating service, which changed her completely. She had received lots of likes and dick picks, she had gone on many dates with lots of men, some were great and some were not, her confidence had gone up, etc. She summed up the whole experience shouting "It's raining men!", and so Vignal had her movie pitch and the song.
To research dating apps, Caroline Vignal signed onto Tinder, and catalogued for months the men's profiles, pictures and messages she received.
Caroline Vignal wondered how to translate on screen the dating app experience, where everything happens on a tiny screen, and the adrenaline rush coming from chatting with people on these apps. She then made the decision to never show the screens, and use the actors' faces to convey the emotions. The show Euphoria reassured her in that regard, as the audience shares the joy, disappointment, or excitement of the teenagers even though all text messages are shown to the audience like subtitles.
