The wait for HBO’s first glimpse “Harry Potter” was a long time ago. Production began in July 2025 at Warner Bros. Leavesden Studios. Months of set photos, casting announcements and fan speculation followed. Now the production team has finally opened the doors and released the first official images and trailer of the upcoming “Harry Potter” series is everything it was cracked up to be.
The trailer shows the back of young Harry Potter, played by Dominic McLaughlinapproaching the Hogwarts Quidditch pitch on a snowy day in a red and gold Gryffindor cloak. His last name and player number are stitched on the back. Before him, a crowd of students pour onto the field beneath the waving house flags of Gryffindor and Hufflepuff.
Keen-eyed fans will have already noticed the Fred and George banner in the corner, a detail that shows just how much care has gone into building this world. In addition to the image, the show’s official Instagram dropped a teaser that gives the clearest indication yet of what this series wants to be. HBO “Harry Potter” era has officially begun.
A new Hogwarts, built from the ground up
One trailer doesn’t tell everything. But it tells you enough. The version of Hogwarts that takes shape here was designed by production designer Mara LePere-Schloopwhose previous credits include Interview With the Vampire and Pachinko. Her involvement indicates a creative ambition to build a school that is grounded, structured and clearly its own. With respect for the films that preceded it. Not mandatory for them.
Principal photography began on July 14, 2025 under the working title “Dark Train,” in the same Leavesden facility where all eight of the original Harry Potter films were made between 2001 and 2011. Filming in the same location has symbolic weight. However, the creative team has made it clear that this is not an innovation.
One will be adjusted each season by JK Rowling seven novels, with the ambition to delve deeper into the source material than two hour films ever could. Warwick Daviswho returns as Professor Flitwick, has described it as a retelling of the stories with more depth and detail than audiences have seen before. That’s the pitch. The first image suggests that the production has the craftsmanship to back this up.

Dominic McLaughlin leads the series as Harry Potter, accompanied by Alastair Stout as Ron Weasley and Arabella Stanton as Hermione Granger. The trio was announced in May 2025 and production began two months later. The supporting cast assembled around it is formidable.
Johannes Lithgow takes on the role of Albus Dumbledore, Janet McTeer plays Minerva McGonagall, Nick Vorst steps into the beloved role of Rubeus Hagrid, and Paapa Essiedu plays Severus Snape. Essiedu’s casting sparked much debate when it was announced. He has since spoken publicly about receiving racist death threats, including messages telling him to quit or face violence. He remains in the role. Further cast includes Johnny Flynn as Lucius Malfoy, Katharina Parkinson as Molly Weasley, Call Powley as Petunia Dursley, Lucas Thallon as Quirinus Quirrell, and Lambert Wilson as Nicolas Flamel. Hans Zimmer composes the score.
Each actor who has signed up has committed to a ten-year journey – the ambition is to complete the entire series across all seven books. That kind of long-term creative commitment is rare in television. It is also exactly what this material needs.
What Daniel Radcliffe said and why it matters
The original Boy Who Lived has been gracious throughout this process. Radcliffe has said publicly that he wrote to McLaughlin to wish him luck in the role and has encouraged people not to ask the new cast to compare themselves to his own portrayal alongside Emma Watson And Rupert Grint. He also gave some honest thought to why a new adaptation makes sense. He told it Stephen Colbert that he was genuinely happy that when his own child grows up and ends up in Harry Potter, there will be a version to watch that doesn’t star their father. If you watched it with your father, he noted, it would snap you out of it. It’s a generous and self-aware observation from someone who spent a decade defining how the world depicted this character.

Filming for the first season is expected to continue until mid-2026, with production on the second season beginning shortly thereafter. The series premieres on HBO in early 2027 with eight episodes in the first season.
The books have sold more than 600 million copies worldwide. The eight films grossed more than $7 billion worldwide. The audience for this series already exists. The question has always been whether the production could honor that audience’s attachment to this world. Based on a carefully composed, detailed photo taken on a snowy day at Hogwarts, the answer is increasingly looking like yes.
