The Complete Guide to HBO’s Harry Potter
Countdown, cast, and every detail so far.
Harry Potter and the Philosopher’s Stone premieres Friday, December 25, 2026 on HBO and HBO Max.
Grab your house scarf and clear your Christmas plans — the Wizarding World is coming home. HBO’s long-awaited television adaptation of Harry Potter premieres on Christmas Day 2026, retelling the books from the very beginning with a brand-new cast and a season for every novel. This page is our living guide to everything officially confirmed so far, and the House Elves update it whenever HBO makes a new announcement.
✦ The Essentials ✦
What We Know at a Glance
The premiere date itself was a surprise gift: the series had long been expected in 2027, but when HBO dropped the first teaser trailer on March 25, 2026, it confirmed the show would arrive months early — on Christmas Day. The episode-by-episode release schedule has not been announced yet, so we don’t know whether episodes will arrive weekly or all at once.

The Decade-Long Plan
This is not a remake of the films — it’s a new, self-described faithful adaptation of the books, with each of the seven novels getting its own full season. The series is planned to run for roughly a decade, letting the young cast grow up alongside their characters, just as the books did.
Season 2, adapting Harry Potter and the Chamber of Secrets, has already been greenlit, with production set to begin in fall 2026 — before season 1 even airs. One thing to temper expectations on: HBO has said new seasons will not arrive every single year, so there will be gaps between trips to Hogwarts.

How to Watch
In the US, the series will air on the HBO linear channel and stream on HBO Max. Internationally, it will stream on HBO Max wherever the platform is available — and after HBO Max’s 2026 launches in the UK, Ireland, Germany, and Italy, that now covers most of the show’s biggest fan markets. If HBO Max isn’t available in your country, the series will typically appear on whichever local service carries HBO content, so keep an eye on your region’s announcements.

Your Questions, Answered
When does the Harry Potter series premiere?
Friday, December 25, 2026 — Christmas Day — on HBO and HBO Max. The date was announced on March 25, 2026 alongside the first teaser trailer, moving the show up from its originally expected 2027 window.
How many episodes are in season 1?
Eight episodes, all adapting Harry Potter and the Philosopher’s Stone. HBO hasn’t yet said whether they’ll be released weekly or all at once.
Is this a remake of the movies?
No — it’s a new adaptation of the books, described by HBO as a faithful one. With a full season per novel instead of a single film, the show has room for details and subplots the movies had to cut.
Who plays Voldemort?
That casting hasn’t been announced yet. Plenty of names have been floated by fans and tabloids, but nothing is official — we’ll report it here the moment HBO confirms.
Is anyone from the original films returning?
Yes — Warwick Davis returns as Professor Flitwick, the role he played across the film series.
Will there be a season 2?
Already confirmed. Season 2 — Harry Potter and the Chamber of Secrets — was greenlit before season 1 even aired, with production beginning in fall 2026. Just don’t expect a new season every year; HBO has said the gaps will be longer than annual.
Is there a trailer?
Yes — the first teaser trailer dropped on March 25, 2026 on HBO Max’s official channels, showing Harry’s life at Privet Drive, his Hogwarts letter, Nick Frost’s Hagrid, and the trio’s first meeting. You can watch it right on this page, in the First Look section above.
