Updated Sep 28, 2026: added the Sep 2 trailer, Casey Bloys’ “not going to be two years” comment on season 2, and re-checked the full cast list against HBO’s latest press release.
The Harry Potter HBO series premieres on Christmas Day, Friday, Dec 25, 2026, on HBO, and it streams on HBO Max. HBO’s own wording is “Christmas 2026,” and the Dec 25 date was reported the day the first teaser dropped. Season 1 is called Harry Potter and the Philosopher’s Stone, runs eight episodes, and stars newcomer Dominic McLaughlin as Harry. Season 2 is already greenlit. Here’s everything that’s actually confirmed, plus what HBO still hasn’t told us.

When does the Harry Potter HBO series come out?
Christmas 2026, which is honestly earlier than anyone expected. When cameras started rolling in July 2025, HBO was still saying the show would debut in 2027. Then on March 25, 2026, at the HBO Max launch event in the UK and Ireland, HBO dropped the first teaser and pulled the premiere into Christmas 2026 (HBO).
What we don’t have yet: an episode schedule. HBO hasn’t said whether all eight episodes drop at once or roll out weekly, or when the finale lands, as of Sep 28, 2026. HBO’s big dramas usually go weekly on Sunday nights, so a Friday premiere is already a bit of a curveball. Our guess is a weekly rollout into early 2027, but that’s a guess, not a date.
Outside the US, it streams on HBO Max wherever the service is available, which now includes the UK, Ireland, Germany and Italy (HBO).
Harry Potter HBO series cast
The big three were announced on May 27, 2025, after a casting search that HBO said drew tens of thousands of kids (HBO). All three are screen newcomers. The adults came in waves through 2025, and HBO’s Sep 2 press release has the full season 1 list.
| Actor | Role | Source |
|---|---|---|
| Dominic McLaughlin | Harry Potter | HBO |
| Arabella Stanton | Hermione Granger | HBO |
| Alastair Stout | Ron Weasley | CNN |
| John Lithgow | Albus Dumbledore | HBO |
| Janet McTeer | Minerva McGonagall | HBO |
| Paapa Essiedu | Severus Snape | HBO |
| Nick Frost | Rubeus Hagrid | HBO |
| Luke Thallon | Quirinus Quirrell | HBO |
| Paul Whitehouse | Argus Filch | HBO |
| Warwick Davis | Filius Flitwick | HBO |
| Lox Pratt | Draco Malfoy | HBO |
| Johnny Flynn | Lucius Malfoy | HBO |
| Katherine Parkinson | Molly Weasley | HBO |
| Bel Powley | Petunia Dursley | HBO |
| Daniel Rigby | Vernon Dursley | HBO |
| Bertie Carvel | Cornelius Fudge | HBO |
| Rory Wilmot | Neville Longbottom | HBO |
| Tristan and Gabriel Harland | Fred and George Weasley | HBO |
| Ruari Spooner | Percy Weasley | HBO |
| Gracie Cochrane | Ginny Weasley | HBO |
| Sirine Saba | Pomona Sprout | HBO |
| Anton Lesser | Garrick Ollivander | HBO |
That’s the core, not the whole thing. HBO’s list also includes Leo Earley (Seamus), Elijah Oshin (Dean), Alessia Leoni (Parvati), Sienna Moosah (Lavender), Finn Stephens and William Nash as Crabbe and Goyle, Amos Kitson as Dudley, Louise Brealey as Madam Hooch, Bríd Brennan as Madam Pomfrey, Richard Durden as Professor Binns and Leigh Gill as Griphook (HBO). Fun detail: Warwick Davis is back as Flitwick, the same part he played in the movies.
Who’s making it
This is basically the Succession crew going to Hogwarts. Francesca Gardiner (Succession, His Dark Materials) writes and showruns, and Mark Mylod (Succession, Game of Thrones, The Last of Us) directs multiple episodes (HBO). J.K. Rowling executive produces alongside Neil Blair, Ruth Kenley-Letts and David Heyman, who produced all eight films. For season 2, writer Jon Brown gets bumped up to co-showrunner (Variety).
How the show adapts the books
The pitch hasn’t changed since Max ordered the show in April 2023: a “faithful adaptation,” one book per season, over roughly a decade (HBO). Rowling said at the time that TV allows a “degree of depth and detail” the movies couldn’t manage. Eight hours for Philosopher’s Stone, a book the 2001 film covered in about two and a half, means room for stuff the movie cut. HBO also keeps promising that the original films stay “at the core of the franchise,” so this isn’t replacing them, at least officially.
Filming
Production started July 14, 2025 at Warner Bros. Studios Leavesden outside London, the same studio where the movies were shot (HBO). Season 2 was set to start filming this fall, per the renewal announcement (Variety). HBO hasn’t announced a start date for those cameras as of Sep 28, 2026.
Trailers
Two so far, both on the official Harry Potter YouTube channel. The first teaser landed March 25, 2026, and HBO says it pulled more than 277 million organic views in 48 hours, more than double its previous record (HBO). The second one, which HBO calls a second teaser, arrived Sep 2 with the Sorting Hat, Quidditch and a lot more Dumbledore and Snape (Deadline).

What about season 2 and beyond?
HBO renewed the show on May 6, 2026, seven months before season 1 even airs, for a Chamber of Secrets season (Variety). Just don’t expect a new season every Christmas. HBO boss Casey Bloys said this month that the gap is “not going to be two years,” but HBO’s “trying hard to keep it as compressed as possible” (Collider, citing Deadline). Reading between the lines: season 2 in 2027 is off the table.
Why it matters
This is arguably the biggest bet HBO has made on a single show since Game of Thrones. A seven-season plan with record-breaking trailer numbers is exactly the kind of long-running event series every streamer wants. If it works, HBO has a holiday-season tentpole for the next decade, the way Thrones owned spring. If it stumbles in season 1, there’s a lot of pre-committed money and time riding on season 2 anyway.
It’s also part of a bigger trend: studios going back to the franchises everyone already knows and stretching them across more screens.

Let’s be real: the risks HBO is taking
We’re curious. We’re also not going to pretend this is a slam dunk.
- Is a remake needed right now? The last film came out in 2011, and the originals are still everywhere. TechRadar ran a whole piece arguing we don’t need a reboot, and plenty of fans agree. HBO’s answer is the extra depth of TV. That only works if the show uses those hours for something the movies didn’t do, not just longer versions of the same scenes.
- The first teaser didn’t wow everyone. Record views don’t mean record love. Forbes rounded up a wave of skeptical social media reactions the day after it dropped (Forbes). The September trailer landed better, and Forbes contributor Erik Kain wrote that it made him a believer (Forbes). Still, a lot of that footage revisits moments fans already know by heart from the movies, and the “remake of a remake” feeling hasn’t fully gone away.
- The clock problem. Seven seasons with child actors, and HBO already can’t do one a year. Every extra month between seasons is a month the kids grow up faster than their characters do. The films dealt with the same thing, but they had a much tighter release schedule for most of the run.
- The Rowling question. Rowling is an executive producer, and her public views on transgender issues have made her involvement a flashpoint since day one. When the show was announced, Bloys said HBO’s priority was “what’s on the screen” and declined to engage on the controversy (Variety). In 2025 he said the show isn’t “secretly being infused” with her views (Deadline). For viewers who care about where their subscription money goes, that’s a real sticking point, and HBO hasn’t changed her role. HBO clearly believes it won’t dent the audience, and the record teaser numbers back that up so far.
To be fair, the team is legit, the casting has been smart, and HBO has a track record with huge book adaptations. The pressure’s all on the first episode now.
What’s next
We’d expect at least one more trailer and an episode schedule before Christmas, though HBO hasn’t promised either. We’ll update this page as soon as HBO drops either, plus the season 2 filming start and any new cast for Chamber of Secrets.
