The Oldest Person in the World Documentary

There’s something kind of wild about spending ten years chasing an idea, especially one that keeps slipping out from under you. That’s what Sam Green does with The Oldest Person in the World (2026), an 87-minute documentary that quietly stood out at the Sundance Film Festival 2026. The concept feels simple at first. Follow the oldest living person on Earth. But that title never stays put for long, and that’s where it gets interesting. Over a decade, Green travels to Japan, Spain, and the United States, meeting people who hold that title, even if only for a moment.

What really pulls you in is how personal it all feels. Green doesn’t hide behind the camera. He lets himself be part of the story, sharing thoughts about his own aging, his family, and his health. It gives the film a reflective, almost conversational tone, like you’re not just watching these lives unfold, you’re sitting with him as he tries to make sense of it all.

And despite the subject, it’s not as heavy as you might expect. Yes, it deals with mortality, but there’s also a quiet warmth running through it. A curiosity. It keeps circling that question we all think about at some point. Is there a secret to living this long, or is it just luck, timing, and a bit of stubbornness?

Visually, it keeps things close and intimate, with cinematography by Yoni Brook and editing from Aaron Wickenden and Green shaping it into something that feels more like a personal essay than a traditional documentary. Some people have compared it to the Up series, which makes sense, but this one feels more reflective than observational.

If you’ve seen The Weather Underground, you’ll recognize Green’s style right away. He’s always been drawn to stories that wander a bit, that take their time. This might be his most human film yet.
