Every four years, the world's biggest sporting event produces a handful of advertisements that outlive the tournament itself. Nike's Secret Tournament in 2002 had Eric Cantona recruiting the world's best players onto a container ship in the middle of the ocean. Adidas's José in 2006 showed a young Spanish kid weaving through defenders on a street in slow motion. Nike's Write the Future in 2010 unfolded Rooney and Drogba's alternate universes in thirty seconds. Then came Nike again in 2014 with Winner Stays, where kids on a concrete pitch suddenly became the world's greatest players in their own heads. These are the ones that live forever, the ones people still send each other.

Last week, Adidas added another one to that list.

Backyard Legends has an elegant premise: Timothée Chalamet assembling a team to beat Clive, Ruthie and Isaak—a neighbourhood trio unbeaten since 1996. They're so formidable that Zidane, Beckham and Del Piero's AI-rendered younger selves showed up only to lose. Messi is there. Bellingham. Lamine Yamal. Trinity Rodman. Bad Bunny. The whole thing is dressed in 90s terrace aesthetics, analogue textures, era-defining hairstyles. By the weekend it had 56 million views on Instagram and the comment sections had settled on one recurring thought: Nike is so cooked.

Great World Cup films work because the lead makes you believe what's happening on screen—and Chalamet is exactly the right person for that job.

Casting Chalamet is one of the smartest decisions in recent sports marketing. Not just because he's culturally ubiquitous right now, though he is. Because his relationship with football is genuine in a way that reads on camera. He grew up playing at Pier 40 in New York, spent summers in France, carries the specific knowledge that separates real fans from people who merely watch. When he says "I was playing at Pier 40 as a kid, thinking about Beckham's free kicks, Del Piero's goals, and Zidane's volleys," that's not a line from a brief. The seam between celebrity and genuine fan is almost always visible. In Backyard Legends you can't find it.

What elevates the film is Chalamet's commitment to the role. Brand films live or die on this. He brings the same intensity to recruiting Trinity Rodman on a basketball court that he brings to everything else. The film moves because he makes it move.

Then there's Messi — the greatest footballer in history, an Adidas athlete his entire career, now playing for Inter Miami with the World Cup on his doorstep. His presence is so powerful that he barely needs to do anything at all.

Beyond Messi, the cast does specific work that adds up to something deliberate. Bellingham and Yamal represent the generation currently inheriting the game. Trinity Rodman brings women's football into the campaign in a way that feels organic rather than obligatory. Bad Bunny, woven into Adidas' identity across Formula 1 and football over the past year, pulls the film into Latin music and streetwear culture without a single moment feeling like a demographic exercise.

The de-aged AI versions of Zidane, Beckham and Del Piero are where the film is at its most technically audacious, and also its most narratively clever. They don't appear to be celebrated. They appear to have lost. The mythology of Clive, Ruthie and Isaak is powerful enough to have beaten the greatest players of a generation, and the film treats this as entirely natural. The technology earns its place in the story, and because it earns its place, you barely notice it's there.

The film doesn't mention the World Cup. No official tournament branding, no countdown, no voice-over connecting the neighborhood pitch to the global stage. The Adidas identity lives only through the balls, the Sambas, the three stripes on the kit.

This is the most important creative decision in the film. Adidas is the official match ball provider and kit supplier to fourteen federations, with €250 million in merchandise already sold. The pressure to advertise that would have been enormous. Someone chose story instead, trusted the feeling would earn the association, and they were right.

Most World Cup advertising forgets to be about football. It tries so hard to be about the World Cup that the game itself disappears. Backyard Legends is different. It's about football in its purest form—the version that exists in car parks, cage pitches, and patches of grass with coats for goalposts. The version that has nothing to do with stadiums or trophies. The film's whole argument, made without a word of explanation, is this: the World Cup is just Clive, Ruthie, and Isaak on a bigger stage.

The last time a campaign at this level pulled that off was Nike's Write the Future. Adidas hasn't been here in a long time. They're here now. And with a month to go before the tournament kicks off, Nike hasn't answered yet.
