Quick Answer
Charli XCX promoted her A24 mockumentary The Moment with a minimalist green wall in Shoreditch that openly declares itself “movie promo,” turning self-aware OOH.
When the promo becomes the punchline
Charli XCX has never played by conventional marketing rules, and the promotion for The Moment is no exception. Rather than rolling out a standard poster campaign, the artist chose a deliberately understated—and deeply self-aware—out-of-home activation in Shoreditch.
The execution was as simple as it was sharp: a wall painted entirely green, unmistakably aligned with Charli’s brat visual language, carrying just one line of text:
“this is movie promo btw.”
No logos. No cast names. No release dates dominating the space. Just a message that knows exactly what it’s doing.

A wall, a color, and cultural timing
The installation formed part of the promotion for The Moment, Charli XCX’s mockumentary created with A24. After debuting at Sundance, the film arrived in cinemas on January 30, supported not by traditional blockbuster tactics, but by cultural relevance and visual restraint.
The choice of Shoreditch—an area synonymous with creative culture and social discovery—ensured the wall functioned less as advertising and more as an urban artifact designed to be photographed, shared and discussed.
OOH built for social circulation
There’s no call to action, no epic tagline, and no attempt to explain the film. Instead, the campaign leans fully into meta-awareness. By explicitly stating that it is movie promotion, the wall disarms skepticism and invites participation through irony.
This kind of OOH isn’t optimized for footfall alone. Its real reach comes from what happens next: camera phones, Instagram Stories, reposts and commentary. The physical wall becomes the spark, while social platforms do the amplification.

Why it works
Charli XCX’s green wall reflects a broader shift in how cultural products are marketed today. When audiences are hyper-aware of advertising, pretending not to advertise—or openly acknowledging it—can feel more honest and engaging than polished spectacle.
The campaign succeeds because it aligns perfectly with Charli’s voice: playful, self-referential and culturally fluent. It doesn’t interrupt the city; it blends into it, knowing that the best promotion today often doesn’t look like promotion at all—even when it tells you that it is.

Summary
Instead of traditional film advertising, Charli XCX embraced irony and simplicity, using a single green wall and a blunt message to transform movie promotion into a meta joke designed for social media.
