THE VALLECAS FILES on HBO is a docuseries exploring the famous case that inspired the Netflix horror movie Verónica. With three episodes, it’s not a long documentary series, but it isn’t a great one either. Read our The Vallecas Files series review here!

THE VALLECAS FILES on HBO is a true crime documentary series. Or rather, it’s more of a supernatural or paranormal event than a crime… or is it?! That’s part of what needs to be examined and what this docuseries explores.

The case covered in this HBO Original is the very same one that inspired the Netflix horror movie Verónica. This docuseries has just three episodes. It’s off to a somewhat rocky start, I found, but it does cover the case well overall.

This is why I don’t mess with Ouija boards

The Vallecas Files documentary series explores the most famous (and infamous) poltergeist case from Spain. A 17-year-old girl died very suddenly and with no apparent cause of death, which sparked an investigation into the cause.

This led to the belief that a paranormal phenomenon was the root of the problem. One that began after a few teenagers played around with an Ouija board.

With this HBO Documentary, it’s now 30 years later, and the family relives the events that made the lives of the Gutiérrez Lázaro family members a nightmare. 

As a horror fan, I follow the rules made famous by horror movies. I am not about to repeat the name Candyman, I wouldn’t say “Let’s split up” or “I’ll be right back” in a sticky situation, and I would never mess around with Ouija boards.

Well, apparently, other people are more adventurous than me. Unsurprisingly, teenagers are even more ready to play with danger. For the record, I didn’t mess around with this stuff as a teenager either.

I’ve always watched horror movies, so I know to be smart about this stuff.

Which horror movie is based on The Vallecas Files case?

The Netflix release from 2018, Veronica, is based on the case from The Vallecas Files. Just like The Enfield Poltergeist was the case featured in The Conjuring 2.

For me and many others, Verónica was a horror movie that hit hard. It was very efficient and became a huge success. So much so that a prequel came out in 2023 with Sister Death.

Obviously, the parts of these true stories that are used in movies can differ quite a lot from the reality of the events. Still, the facts revealed in The Vallecas Files docuseries are very brutal. Different, in some ways, but extremely scary.

Watch The Vallecas Files docuseries on HBO Max

This original documentary series was directed by Noemí Redondo and created by Irene del Cerro and Jorge Pérez Vega. Produced by Buendía Estudios for HBO Max, this is a docuseries that audiences worldwide should want to watch.

Yes, especially due to the success of the Netflix horror movie Veronica. It feels like a shame that Netflix didn’t make its own documentary, but HBO has always been good at documentaries as well.

I have to admit that the true story told in The Vallecas Files was an absolute nightmare. Of course, it was also a case where manipulation played a much bigger role than the kids in the family had a chance of recognizing back then.

This is a three-part documentary that allows the now-adult children of the family to tell the story. A story of what they experienced and how they understand, as adults, what was all very confusing as children.

The Vallecas Files docuseries is on HBO Max on November 7, 2025.
