Harry Potter fans across the world were pretty divided by the news in 2023 that HBO were reportedly making a TV adaptation of the beloved franchise, but now it's well on its way with a number of roles now filled, including the iconic roles of Harry Potter, Hermione Granger and Ron Weasley.

As well as filling the well-known roles, actors such as John Lithgow, Paapa Essiedu, Warwick Davis and Nick Frost have all been confirmed, along with Janet McTeer, Luke Thallon and Paul Whitehouse. In July 2025, HBO then shared the first look of Dominic McLaughlin in the lead role of Harry Potter, and some new cast announcements, as they confirmed production has started.

First look at Harry Potter TV series

After years of building excitement, fans have now had the chance to see the first look at the new Harry Potter TV series. In the Instagram post by HBO, they confirmed the series was now in production, writing: 'First-years, step forward.

'The HBO Original Harry Potter series is now in production.'

Following this post, many fans left excited messages saying how perfect he was for the role. One fan commented: 'Ok. Yup. He was the perfect choice 🙌', with another saying: 'Good luck little Harry. Please protect him from all the haters 🥲'.

Another fan wrote: 'Good luck little Harry. We'll be watching your career with great interest'.

It was previously revealed that Harry was to be played by Dominic McLaughlin. Dominic is a Scottish actor who is set to appear in two TV shows over the next year, a BBC action adventure called Gifted and a Sky comedy called Grow.

A day after the first photo of Harry was revealed, HBO shared a photo of Nick Frost as Hagrid, writing: 'Nick Frost has walked his first day in the big boots of Hagrid on the set of the new HBO Original Harry Potter series.'

How was it announced?

In a tweet when the series was first announced in April 2023, HBO shared a 30-second teaser alongside the caption: 'Your Hogwarts letter is here. Max has ordered the first ever #HarryPotter scripted television series, a faithful adaptation of the iconic books. #StreamOnMax.'

Who will direct the series?

Mark Mylod and Francesca Gardiner will direct the new HBO Harry Potter series, with Francesca also taking on the role of writer.

Francesca worked on the HBO adaptation of His Dark Materials as well as Killing Eve, and Mark worked on Game of Thrones, the second season of The Last of Us and also 2022 film The Menu. Both additionally worked on lauded series Succession.

What will the plot for the TV series be?

HBO announced back in 2023: "The series will feature a new cast to lead a new generation of fandom, full of the fantastic detail and much-loved characters Harry Potter fans have loved for over 25 years."

According to Bloomberg's previous report, the series will be made up of seven seasons to cover each of the seven books, which will apparently allow the makers to "delve further" into more detail than the eight films starring Daniel Radcliffe, Emma Watson and Rupert Grint as Harry Potter, Hermione Grainger and Ron Weasley.

This might come as welcome news to fans, who have often felt that certain storylines and characters were omitted from the original film series due to time limits.

Author J. K. Rowling will "be involved" in the series to ensure it "remains loyal to her original material", but it's thought she will not be a hands-on member of the team.

This isn't the first time that HBO have teamed up with the world of Harry Potter, after being responsible for the 20th anniversary Harry Potter reunion, Return to Hogwarts, released in January 2022 that saw most of the main cast return to share their memories at The Making of Harry Potter tour in Watford.

Who will be cast in the new Harry Potter TV adaption?

There had been lots of rumours circulating about who would be cast to play the iconic characters associated with the Harry Potter franchise, and now a lot of cast members have been confirmed, including Harry, Ron and Hermione.

Who will play Harry, Ron and Hermoine in the new TV series?

In early September 2024, a casting call was announced for the main roles of Harry, Ron and Hermione. Bosses revealed they were on the lookout for aspiring young actors from the UK and Ireland, aged 9-11.

In May 2025, three newcomers were announced for the highly sought-after roles, Dominic McLaughlin in the role of Harry Potter, Arabella Stanton as Hermione Granger, and Alastair Stout as Ron Weasley.

Following his casting as Harry, Dominic's school, The Performance Academy, wrote: 'We are not sure that this will ever feel real but we said from the start that Dominic was the perfect Harry & we are thrilled for everyone else to see this soon too.

'Dominic, we will forever be proud of you! We have had an incredible journey with you these last 5 years at TPA and can’t wait for what’s next on this journey!'

Who else is in the cast?

John Lithgow is best known for his roles in 3rd Rock From The Sun (1996-2001), Dexter (2006-2013), The Crown (as Winston Churchill) and voicing Lord Farquaad in the Shrek movies — and now he's set to step in to the role of headmaster Albus Dumbledore in the new HBO series.

Speaking to ScreenRant in February 2025, he said: "Well, it came as a total surprise to me. I just got the phone call up at the Sundance Film Festival for yet another film, and it was not an easy decision because it's going to define me for the last chapter of my life, I'm afraid.

"But I'm very excited. Some wonderful people are turning their attention back to Harry Potter. That's why it's been such a hard decision. I'll be about 87 years old at the wrap party, but I've said yes."

For other roles, the confirmed cast includes Janet McTeer as Minerva McGonagall, Paapa Essiedu as Severus Snape, Nick Frost as Rubeus Hagrid, Luke Thallon as Quirinus Quirrell, and Paul Whitehouse as Argus Filch.

Warwick Davis will also reprise his role as Professor Flitwick in the TV series, after appearing in the original movies. The news was announced on 1st September, when filmmakers shared a picture on Instagram, revealing more additions to the cast. They wrote:
