To build on the anticipation of the release of Marty Supreme, GrandSon partnered with A24 and Nahmias to transform a raw Los Angeles gallery into a one-day retail activation that blurred the lines between a fashion launch, film promotion, and a viral pop-culture moment. From ideation, to custom design and build, GrandSon created a viral experience that fans will never forget. The immersive event invited fans to step into the world of Marty Supreme through exclusive merchandise, custom sporty installations, bumping music, and stylish photo-ops. What began as a retail pop-up evolved into an energetic viral moment, generating widespread organic media coverage. The goal was more than just to sell a product. It was to demonstrate how a thoughtfully produced physical experience can amplify excitement around a film far beyond the walls of the one day event. The day before the opening, Timothée Chalamet shared the pop-up location on Instagram. Six minutes after his post, fans were lined up outside, planning to stay overnight. By the next morning the line wrapped around the block, surrounded by news crews, helicopters, and the infamous Marty Supreme blimp. Marty Supreme completely took over Western Ave, Los Angeles. GrandSon managed guest flow, staffing, security, and operations throughout the day, adapting in real time to overwhelming demand while maintaining the experience for every guest. The activation remained open for two extra hours to accommodate for the length of the line. The exclusive merch sold out in a matter of hours, with its online resale value skyrocketing into the thousands of dollars. A physical moment that fans could not ignore. Disrupting the media.
