What Does The New Footage Show?
In the new HBO Max preview, released on May 24, 2026, Ollivander appears with one of the book series’ most recognizable lines.
“Mr. Potter, I think we can expect great things from you,” he says. “Let’s see who you are.”
It is a small moment, but it is designed to reassure viewers that the series is leaning into the text’s familiar beats. The teaser also includes quick shots of Harry and his friends at Hogwarts, including students walking through the castle corridors and heading out for a Quidditch match.
Some of those Hogwarts glimpses had already appeared in an earlier trailer, so the main new draw here is Lesser’s debut as the wandmaker. For a show that will be judged as much on atmosphere as plot, even a few seconds of Diagon Alley atmosphere is apparently enough to restart the internet’s inspection committee.
What Else Was In HBO’s Preview?
The Harry Potter footage was part of a broader HBO trailer highlighting several upcoming and returning series. Alongside the wizarding-world material, the preview showed:
- House of the Dragon
- Stuart Saves the Universe, the The Big Bang Theory spinoff
- Lanterns
- The Gilded Age
- Other HBO and HBO Max projects
The Harry Potter segment appears around the 1:15 mark in the preview. Its placement suggests HBO is still treating the series as one of its biggest long-term bets, which is not exactly subtle given the scale of the production already being reported.
How Big Is HBO Going With This Adaptation?
Writing is already underway on HBO’s second Harry Potter television season, even as the first season remains in production planning and rollout mode. Filming is expected to begin later this year, with producers trying to keep the enormous project moving quickly.
That pace matters because the adaptation is planned as a long-term retelling of the book series. Fans have already raised concerns that, if the show stretches across many seasons, it may not finish airing until the early 2040s. That is a long wait for a final battle, even by premium television standards.
Recent reporting around the production has also pointed to the size and cost of the build. A major set leak recently gave fans a detailed look at the new Diagon Alley, while HBO has acknowledged that it is making an unusually large financial investment in the series.
The expensive sets and props have reportedly created a less magical problem: theft. Items including broomsticks have been microchipped to discourage people from walking off with souvenirs they were not invited to own.
Why Ollivander’s First Look Matters
For casual viewers, this is simply a first glimpse of a respected actor in a memorable supporting role. For longtime readers, it is one of the early tests of the show’s tone.
Ollivander is not just a shopkeeper. He introduces the idea that magic in this world has rules, history, and consequences. His scene with Harry is quiet, but it points toward the larger conflict that will define the story.
That is why HBO’s reveal is more than a casting footnote. Lesser’s Ollivander has to make a familiar moment feel alive again, without turning it into museum glass. The teaser suggests HBO knows exactly how closely fans will be watching, which is probably wise. They have had plenty of practice.
