The Foundation of Formality
Before we get to the controversies, let's establish the baseline: Cannes is serious about its black-tie tradition. Unlike the Oscars or the Met Gala, which encourage creative interpretations of a theme, Cannes operates on a stricter, more old-world frequency. For the prestigious evening premieres at the Palais des Festivals, the official mandate is black tie—a tuxedo for men and an evening gown for women. This isn't a suggestion; it's a condition of entry. Security has been known to turn people away for not meeting the standard, creating an atmosphere of high-stakes formality. This code is the bedrock upon which all other controversies are built. It establishes the festival not just as a celebration of film, but as a bastion of a specific, tightly
controlled European elegance that often clashes with modern sensibilities.
The Flashpoint: High Heels and Rebellion
Nothing encapsulates the Cannes rules debate quite like the infamous “heels rule.” For years, reports circulated that women were being denied entry to premieres for wearing flat shoes. While festival director Thierry Frémaux has repeatedly denied that a written rule exists, the on-the-ground reality suggests a powerful expectation. The issue exploded in 2015 when a group of women in their 50s were reportedly turned away for wearing rhinestone flats. The backlash was swift and global, framing the issue as a sexist and outdated demand. Since then, the red carpet has become a site of quiet rebellion. Stars like Julia Roberts have walked it barefoot, and in 2018, Kristen Stewart famously removed her black Christian Louboutin heels in the middle of the carpet, holding them as she ascended the stairs. These moments go viral because they're a perfect visual metaphor: a modern woman refusing to suffer for an archaic, gendered standard of beauty.
The Great Selfie Standoff
In 2018, the festival officially banned selfies on the red carpet. Thierry Frémaux decried them as “grotesque” and blamed them for slowing down the elegant procession into the theater. He argued that the carpet should be about the artists and the art, not about a fan’s quick snap for social media. This rule created a fascinating culture clash. On one hand, you have the festival's desire to preserve an aura of mystique and old-school glamour. On the other, you have the reality of modern celebrity, where social media engagement is part of the job. The ban pits the timeless image of the festival against the hyper-current, democratized nature of the internet. While some stars praised the move for helping them stay in the moment, others found it out of touch. The tension goes viral because it asks a fundamental question about fame today: Is the red carpet a sacred space for art or just another backdrop for the content machine?
The Battle Over the Big Screen
Not all of Cannes’ viral rules are about fashion. A more recent and industry-shaking controversy revolves around what even qualifies as a film. In 2017, after two Netflix films were selected for the festival’s main competition, French exhibitors protested. Their argument was that a film not guaranteed a theatrical release in France shouldn't be eligible for the festival's top prize, the Palme d'Or. In response, Cannes instituted a rule requiring all competition films to have a planned French theatrical run. This effectively locked out Netflix and other streaming giants who prioritize their own platforms over traditional cinema releases. This debate goes viral because it’s a proxy war for the soul of the film industry itself. Is a movie still a movie if it’s never shown in a movie theater? Cannes, by planting its flag firmly on the side of the theatrical experience, has made itself a central battleground in the ongoing streaming wars, ensuring its rules are debated far beyond the red carpet.
