HARRY POTTER TV Series Will Be "The Streaming Event Of The Decade" According To HBO Exec

Excitement is already high for HBO's upcoming Harry Potter TV series, and one executive is billing the series as "the biggest streaming event in the history of HBO Max."

Those of you in the UK will be excited to know that HBO Max is finally coming to the country on Thursday, March 26. Unsurprisingly, the streamer has also made sure to hype up one specific series to potential subscribers: Harry Potter.

The show, which is expected to run for at least 7 seasons (covering one book for each batch of episodes), is a decade-long commitment on HBO's part. It will bring the Boy Wizard back to our screens after Harry Potter and the Deathly Hallows: Part 2 wrapped up the movie franchise in 2011.

There's been the expected level of scepticism from fans, not to mention threats of boycotts from those unhappy with J.K. Rowling's anti-trans stance on social media. Despite that, it's hard to imagine Harry Potter being anything other than a hit.

J.B. Perrette, CEO and President of Global Streaming and Games at Warner Bros. Discovery, said (via SFFGazette.com), "[Harry Potter] producer David Heyman will tell you the scope of the production, the detail, the meticulousness of what they are going through and what they are building. It takes theatrical to a whole different level."

"In the series, you can go deeper and tell more of the pieces that you didn’t capture in a two-hour movie. Casey [Bloys, Chairman and CEO of HBO and HBO Max Content] doesn’t like me saying this, but I really think this is the streaming event of the decade."

"The team have been waiting for so long to deliver this in a market as big as important as the UK," Perrett added, reiterating that Harry Potter will be "the biggest streaming event in the history of HBO Max and arguably in streaming, period. It’s number one, two and three in many ways."

That's quite the proclamation, but it's no secret that Harry Potter is a major investment for WBD. Beyond subscribers, the company looks to cash in big time on advertising and new Wizarding World merchandise.

The benefit of a TV series is, as Perrette suggests, the opportunity to expand on moments glossed over (or missing from) a two-hour movie. We may even get some new scenes, as Lucius Malfoy is set to appear in Harry Potter Season 1, despite not appearing on the page until The Chamber of Secrets

Dominic McLaughlin has been cast in the role of Harry Potter, with Arabella Stanton as Hermione Granger, and Alastair Stout as Ron Weasley.

Joining them will be Lox Pratt as Draco Malfoy, Rory Wilmot as Neville Longbottom, Tristan Harland as Fred Weasley, Gabriel Harland as George Weasley, Ruari Spooner as Percy Weasley, Gracie Cochrane as Ginny Weasley, Leo Earley as Seamus Finnigan, Alessia Leoni as Parvati Patil, Sienna Moosah as Lavender Brown, Amos Kitson as Dudley Dursley, Elijah Oshin as Dean Thomas, Finn Stephens as Vincent Crabbe, and William Nash as Gregory Goyle.

Harry Potter's adult cast includes John Lithgow as Albus Dumbledore, Janet McTeer as Minerva McGonagall, Paapa Essiedu as Severus Snape, Nick Frost as Rubeus Hagrid, Luke Thallon as Quirinus Quirrell, Louise Brealey as Madam Rolanda Hooch, Paul Whitehouse as Argus Filch, Sirine Saba as Pomona Sprout, Richard Durden as Cuthbert Binns, Bríd Brennan as Madam Poppy Pomfrey, and Warwick Davis as Filius Flitwick.

The series will also feature Katherine Parkinson as Molly Weasley, Johnny Flynn as Lucius Malfoy, Bel Powley as Petunia Dursley, Daniel Rigby as Vernon Dursley, Anton Lesser as Garrick Ollivander, Bertie Carvel as Cornelius Fudge, and Leigh Gill as Griphook.

There's still no word on who will play Lord Voldemort, despite continued speculation that Cillian Murphy has landed the coveted role.

Harry Potter is written and executive-produced by Francesca Gardiner. Mark Mylod will executive produce and direct multiple episodes of the series for HBO in association with Brontë Film and TV and Warner Bros. Television. The series is executive produced by J.K. Rowling, Neil Blair, and Ruth Kenley-Letts of Brontë Film and TV, and David Heyman of Heyday Films.

HBO's Harry Potter TV series premieres in 2027.

I really don't get the appeal here. I already saw the Harry Potter movies. Why would I be interested in watching it again with slightly less talented actors, slightly worse costume design, and slightly worse pacing?

@InfinitePunches - don’t act like you went into the original Harry Potter to know any of those actors and if you did know any of the older actors then gosh you are probably too old anyway for the demographic. Yes it’s enjoyable for all but remember it’s a kids book, kids movie and will be a show for kids, tv pg. if you are a fan of the books you know the movies left a lot of meat off bone. So there is a lot more they can do with the series they didn’t do with the movies. Right now they have a graphic audio of the book series been released this year, cool voices, Robert Baratheon is hagrid, Jon snow professor quill, and a lot of other game of thrones alum are voicing characters but even that is already better than the movies in terms of depth.

@whoknows - I read those books. Almost nothing of significance is missing from the movies. But thank God this do-over is probably going to include the subplot about Hermione advocating for the freeing of the slaves only to find out that all the slaves actually enjoy being in slavery.

They're trying to emulate the success of those awful Disney live action remakes. Just repackaging something that worked a generation ago. But without the change in medium, I don't think even kids will be interested in this.

The first two seasons are going to be carbon copies of the films, unless they add some extras to it, since the first two followed the books pretty close.

Honestly , I am not sure about that but I do think it will be one of the biggest streaming events/launches not just for HBO Max but overall thus far tbh…

People who are well within their rights to boycott the show won’t be checking it out but the ones that are merely skeptical will definitely give it a watch just to even see if their concerns were valid or not alongside the ones that are legit excited.

Anyway , personally I’m liking the creative team & cast so far hence I’m looking forward to the show and hope it turns out well!!.

If this doesn't get enough viewers Netflix will cancel it after 2 seasons.

I hope it's good so newer generations can get some interest in reading books instead of social media crap.

Hah! Fat chance.
This is different from, say, reintroducing Batman or James Bond but telling a totally new story with them. This is the EXACT SAME STORY, beat for beat, just with some new details to fill out the extended time. But it's very much "been there, done that". I don't know how that's going to excite anyone after an 8-film series covered everything. It's like saying, "We're going to remake The Dark Knight - the exact same plot, just with different actors". Why would you do that?
This series has so much going against it:
- People who already saw the Harry Potter series and don't care to take the same ride yet again.
- People who are ultra-liberal and mad at JK Rowling for her trans stance.
- People who are ultra-conservative and mad at the "woke" reinterpretation, like casting a black guy as Snape.
- People who never cared about Potter anyway.
With the high production costs, I don't see this series making it all the way through to the end of the story. It'll get canceled before season 5.

Hope Netflix cancels this. The current Wizarding World is still in pop culture consciousness, and is still thriving with Hogwarts Legacy (2) and Universal Studios themed lands.

Think they're far better off expanding upon the existing movies (like with Tales of Beedle the Bard). Everybody knows them, and the show will always be compared to it.
TheVisionary25
TheVisionary25 - 2/9/2026, 3:18 PM
@bkmeijer1 - probably not gonna happen since Netflix likely sees money in it due to the Wizarding World still being in the public consciousness.

I would have loved though a detective noir show about Aurors or a drama about the founders of Hogwarts moreso then another HP adaptation but we could still get that if this is successful.
bkmeijer1
bkmeijer1 - 2/9/2026, 5:50 PM
@TheVisionary25 - even then, I think there's more money to be made from the current Wizarding World.

Even though the Cursed Child has it's issues, I bet it'll still be hugely popular with the movie audience. Especially if Radcliffe, Watson and Grint return.

Guess we'll see if the first season does well. Could always go back to the OG universe

This is going to be massive. You can bet Netflix will do multiple theatrical finales down the road like they did for Stranger Things. I wish they didn't reuse sets and costumes but it'll save so much money and time

Deja Vu. Deja vu.

Member when Star Wars was hyped for streaming and most of it kinda sucks now?

And member when they did this with Marvel streaming and Marvel kinda sucks NOW?

And member when they did this with Lord of the Rings streaming...and most of it kinda sucks now?

If WB breathes new life into Harry Potter through streaming, they will be defying Science at this point lol
