You have to pick me because I'm dynamite, I'm good vibes
For two decades, the cameras of Gran Hermano have captured life inside the house — but never the moment before it begins. Now, as the show enters its twentieth season, Telecinco is pulling back the curtain on the invisible machinery of casting itself, inviting audiences to witness in real time the selection of ordinary people who will shape an entire social world. Hosted by Nagore Robles — who once stood before those same judges as a twenty-six-year-old from Bilbao insisting she was dynamite — the new format 'Uno de GH20' asks a quiet but consequential question: what changes when the audience is no longer kept outside the room?
- For the first time in Gran Hermano's history, the casting process — long hidden behind closed doors — is being streamed live, 24 hours a day, with no editing or curation.
- The stakes are unusually high: this is a season of anonymous contestants, meaning the personalities chosen in these hours will define the entire social ecosystem of the house.
- Nagore Robles brings a rare dual authority to the role — she was selected through this very process in 2009, and now she is the one watching others navigate it.
- The format dismantles the traditional boundary between production and audience, turning passive viewers into witnesses of the decisions that shape the show they watch.
- Whether 'Uno de GH20' becomes a permanent shift in reality TV or a singular experiment hinges entirely on how audiences respond to seeing the machinery exposed.
Gran Hermano is doing something it has never done before: opening its casting room to the public. For its twentieth season, Telecinco has launched 'Uno de GH20', a live format that streams the final selection phase around the clock, with no editing, no highlights, no curated moments — just the raw process of choosing who enters the house.
Hosting the venture is Nagore Robles, a television presenter who understands the weight of that casting room from personal experience. In 2009, at twenty-six, she walked into a Gran Hermano selection and told the committee she was dynamite, good vibes around the clock, and great television. She was right. She made it through. Now, sixteen years later, she's on the other side — not as a contestant, but as the person watching others try to do what she once did.
The format represents a meaningful rupture with how reality television has always worked. Casting has traditionally been the invisible part — decisions made behind closed doors that audiences never see. 'Uno de GH20' removes that wall entirely, letting viewers witness the same process that will determine who lives in the house for the coming season.
The timing adds another layer of significance. Because this season features anonymous contestants rather than public figures, personality and group dynamics become everything. The people selected in these twenty-four hours will define the entire social world the show inhabits.
For audiences, the appeal is access and transparency — the chance to form opinions about the cast before they even enter the house, and to understand the reasoning behind who makes the cut. Robles has described her approach with characteristic self-awareness: demanding, but with humor, and with a genuine desire to learn. Whether this format becomes a fixture or a one-time experiment will depend on how viewers respond to watching the machinery of selection laid bare.
For the first time in its history, Gran Hermano is opening its casting room to the public. The show has launched 'Uno de GH20', a new reality format that will stream the final selection process live, around the clock, for the twentieth season of the program. Nagore Robles, a television presenter, is hosting the venture—and she knows exactly what it feels like to be on the other side of those cameras.
Robles herself walked into a Gran Hermano casting in 2009, at twenty-six years old, with the kind of confidence that either lands you on television or becomes a funny story you tell later. "I'm from Bilbao," she told the selection committee then. "You have to pick me because I'm dynamite, I'm good vibes around the clock, and I'd be great television." She was right. She made it through. She became part of the show.
Now, sixteen years later, she's on the other side of the process. The format she's hosting represents something the show has never attempted before: letting viewers watch the entire final phase of casting unfold in real time. No editing, no highlights package, no curated best moments. Twenty-four hours of live footage as potential contestants interact, compete, and ultimately get sorted into the group that will enter the house for the season.
It's a significant shift in how reality television typically works. Casting has always been the invisible machinery—the part that happens behind closed doors, the decisions made by producers and judges that viewers never see. 'Uno de GH20' dismantles that wall. The audience gets to witness the same process that selected Robles all those years ago, the same process that will determine who lives in the house for the coming season.
Robles has spoken about her approach to hosting the new format with a kind of self-aware humor. She describes herself as "a demanding presenter, but with humor and a desire to learn." It's the kind of thing someone says when they understand they're stepping into unfamiliar territory—not as a contestant this time, but as the person making the calls. She's bringing her own experience as a former participant into the role, which gives the format a particular texture: someone who has been through the selection gauntlet is now watching others go through it.
The timing matters too. Gran Hermano is heading into its twentieth season with anonymous contestants—meaning the focus will be on personality and dynamics rather than pre-existing fame. That makes the casting process even more central to what the season will become. The people selected in these twenty-four hours will determine the entire social ecosystem of the house.
For viewers, the appeal is straightforward: transparency, access, and the chance to form opinions about the final cast before they even enter the house. It's a form of participation that goes beyond voting or commenting online. It's witnessing the actual selection, seeing the same people the producers see, and understanding the reasoning behind who makes the cut. Whether this format becomes a permanent fixture or remains a one-time experiment will likely depend on how audiences respond to watching the machinery of casting laid bare.

The Hearth Conversation Another angle on the story
Why does it matter that viewers can see the casting process now? What changes when you remove that wall between the audience and the selection room?
Everything, really. Casting has always been the secret. You see the result—the people in the house—but you never see how they got chosen or who didn't make it. Now the audience gets to form their own judgments about the selection. They'll see things the producers see.
Does that create pressure on the people being cast? Knowing millions are watching them compete for a spot?
Absolutely. It's a different kind of performance. You're not just trying to impress the judges anymore. You're trying to impress an invisible audience that's going to live with you for months if you get in.
And Nagore Robles—she's been through this herself. Does that change the dynamic of her hosting?
She understands what it feels like to be in that chair, trying to convince people you belong on television. That's not something you forget. She can see the desperation, the calculation, the genuine moments. She's been all of those things.
Is this format a way of making the show more democratic, or is it just a marketing move?
Probably both. But it's also honest in a way reality TV usually isn't. You're not hiding the process anymore. You're saying: here's how we choose. Judge for yourself if we're right.
