Here’s everything we know about the Harry Potter TV show, including release date updates, cast announcements, plot speculation, and more.

There’s no denying that even now, there’s still a market for a series set in Harry Potter‘s Wizarding World.

Some fans have been calling for a new TV show since the last of the Harry Potter movies, Deathly Hallows Part 2, released in 2011.

Eventually, another adaptation of the Harry Potter books was confirmed by Max — and met with a mostly negative response. Here’s what’s been announced about the series so far.


Does the Harry Potter TV show have a release date?

The Harry Potter TV show will be released on Max in 2026, according to Warner Bros. Discovery CEO David Zaslav.

The show was announced as part of Warner Bros. Discovery’s presentation on April 12, 2023, primarily to reveal that HBO Max and Discovery+ would merge into a new streaming service named Max.

Zaslav has updated investors on earning calls, and Max is eyeing a 2026 release.

Who’s in the Harry Potter TV show cast?

No cast has been announced for the Harry Potter TV series, but it will feature new actors in the key roles.

Lord Voldemort, Dumbledore, and the other eclectic characters from the movies will be brought back to life by new talent.

That includes the core trio Harry Potter, Hermione Granger, and Ron Weasley, played in the movies by Daniel Radcliffe, Emma Watson, and Rupert Grint respectively. 

Are any original actors returning in the Harry Potter TV series?

The original Harry Potter cast will not be the stars of the TV show. Some supporting cast could return or cameo but it’s unlikely.

Emma Watson as Hermione Granger, Rupert Grint as Ron Weasley, and Daniel Radcliffe as Harry Potter in Deathly Hallows Part 2.
Deathly Hallows Part 2 was the final movie.

A press release confirmed the series will have a “new cast to lead a new generation of fandom, full of the fantastic detail, much-loved characters, and dramatic locations that Harry Potter fans have loved for over 25 years.”

Radcliffe, Watson, and Grint have publicly spoken out against JK Rowling’s views on transgender people, so don’t hold your breath waiting for those actors to appear.

As for the original supporting cast, there’s a chance they could appear in some capacity, likely in cameo-style roles. But given this would muddy the canon and make things confusing for no good reason, we don’t expect it to happen.

Harry Potter TV show plot: What is it about?

The Harry Potter show will last 10 years and faithfully adapt all seven books, following Harry, Ron, and Hermoine at Hogwarts and beyond.

Max said it will be “produced with the same epic craft, love and care this global franchise is known for… each season will be authentic to the original books and bring Harry Potter and these incredible adventures to new audiences around the world, while the original, classic and beloved films will remain at the core of the franchise and available to watch globally.”

According to Casey Bloys, Chairman and CEO of HBO and Max Content, it will be a “faithful adaptation.”

As well as allowing for the story to be told on screen in more depth than the movies, it also paves the way for a new generation of actors to grow up in their roles as the original kids did.

In many ways, TV as a long-form format makes sense for a long book series like Harry Potter. Television is the home of long character arcs, expansive world-building, and natural character development. There’s more time to tell more story.

The drawbacks are in the budget and scope. Even the most expensive TV series typically won’t visually stand up to a big blockbuster. While the first couple of Harry Potter movies can be hammy in their effects, much of the film series was shot on-location and the CGI improved with every entry.

While even the best movies couldn’t go into depth to the same degree a long TV series can, they were beloved by fans and well-received by critics. Holding a candle to their legacy will be hard. Not to mention the retreading of the same major story beats.

Is there a Harry Potter TV show trailer?

There’s an announcement teaser for the Harry Potter TV show but no full trailer yet.

If the series does release in 2026, then late 2025 would be a good appreciation for a full trailer.

The announcement video revealed the logo for the show, which is the same as the movies. It also features the theme, composed by John Williams, just like the movies.

How to watch the Harry Potter TV show

The Harry Potter TV show will stream exclusively on Max in the US in 2026.

You’ll need a subscription to watch it when the time comes because the series is a Max original.

Distribution rights for other regions are up in the air right now, as Max is only available in select countries: the United States, Latin America, the Caribbean, and parts of Europe.

Harry Potter TV show rumors and fan casts

Fans have been suggesting Cillian Murphy as Voldemort, Andrew Scott as Snape, and Gillian Anderson as Professor McGonagall for the Harry Potter TV show.

We’ll see another version of the Battle of Hogwarts in the show.

While many fans have expressed concerns over the inevitable failure to recapture the magic of the series and the attachment to the actors, others have been trying to fill the roles with a few proposed casting ideas.

MyCast is a great website to visit if you’re looking for fun fan casts, as people can vote for actors. The children will almost certainly be unknowns given the young age they need to start the series at, so the adults in the story are more exciting to consider from a fan-casting perspective.

We think these ideas stand out and have a good number of votes.

Our Harry Potter fan cast:

  • Cillian Murphy as Lord Voldemort
  • Jared Harris as Albus Dumbledore
  • Andrew Scott as Severus Snape
  • Gillian Anderson as Minerva McGonagall
  • Nick Frost as Hagrid
  • Olivia Colman as Dolores Umbridge
  • Lashana Lynch as Poppy Pomfrey
  • Sophie Okonedo as Aurora Sinistra

How many seasons of the Harry Potter TV show will there be?

The Harry Potter TV show is expected to have seven seasons, one per book. This is unconfirmed.

Max said it will be a “decade-long series,” which fits with the timeline of seven seasons when breaks between filming and any potential delays are accounted for.

Is JK Rowling involved in the Harry Potter TV show?

JK Rowling is an executive producer on the Harry Potter TV show, so is involved financially and creatively, to some degree.

Wizarding World is a trademark of Rowling and Warner Bros. Entertainment Inc. She is compensated for content that uses the world and characters and is often creatively involved, as is the case here.

Some fans say they will not watch it for that reason.
