The magical world of Harry Potter is getting much bigger. Warner Bros Discovery executives have shared new details about how they plan to expand the Wizarding World across streaming, merchandise, and live experiences. The company is putting its full weight behind the franchise, with the upcoming HBO series positioned as the centerpiece of a strategy that reaches far beyond television.
JB Perrette, who runs global streaming and games for Warner Bros Discovery, recently spoke in London about what fans can expect. He visited the sets at Leavesden Studios near London and came away impressed by what he saw. The production quality, according to Perrette, takes things to a different level. He described the attention to detail as meticulous and said the scale of what they are building matches what you would expect from major theatrical films .
The new Harry Potter TV series is not just another show for the company. Perrette called it the potential “streaming event of the decade” during his remarks at an event announcing HBO Max’s European launch . He acknowledged that HBO boss Casey Bloys might not love him saying that publicly, but he stands by the statement. The series arrives at a crucial time as Warner Bros Discovery pushes HBO Max into more international markets, with the UK and Europe being major priorities .
What We Know About the Harry Potter TV Series Release
The Harry Potter TV series is scheduled to arrive in 2027 . Warner Bros Discovery CEO David Zaslav previously confirmed the company was targeting a 2026 debut during an earnings call, but more recent reports point to 2027 as the official premiere window . The show will stream on Max (formerly HBO Max) in the United States and will be available on the platform internationally as it expands across Europe starting March 26 .
Viewers in the UK, Canada, Australia, and India will also get the series through Max or local streaming partners once the international rollout completes. Warner Bros Discovery has positioned this show as a key driver for subscriber growth worldwide .
The series plans to run for more than seven seasons, with each book getting its own season. This long format allows the story to breathe in ways the movies could not. Characters and subplots that got less screen time in the films will now have room to develop properly .
The Cast Bringing the Wizarding World to Life
A fresh group of young actors will carry the story forward. Dominic McLaughlin takes on the role of Harry Potter. Alastair Stout will play Ron Weasley, and Arabella Stanton steps in as Hermione Granger . These three young performers have the difficult task of following Daniel Radcliffe, Rupert Grint, and Emma Watson.
Radcliffe has already reached out to McLaughlin. He wrote a letter to pass the torch and offer support. Radcliffe said he wanted the new Harry to have an even better time than he did, acknowledging how much the experience shaped his own life .
The adult cast brings serious awards credentials. Seven-time Emmy winner John Lithgow will play Albus Dumbledore . Janet McTeer joins as Professor McGonagall. Paapa Essiedu takes on the complex role of Severus Snape. Nick Frost brings his talents to Rubeus Hagrid. Luke Thallon plays Professor Quirrell, and Paul Whitehouse is cast as Argus Filch .
Lorax Pratt will play Draco Malfoy. In recent interviews, Pratt promised viewers will see sides of Draco never fully explored before. The series moves beyond Harry’s point of view, allowing audiences to understand characters like Draco more deeply. Pratt explained that Draco comes across as one-dimensional in the films, but the show will show his home life and relationship with his father Lucius. These scenes help explain why Draco becomes the person he is .
Francesca Gardiner serves as showrunner, with Mark Mylod executive producing and directing multiple episodes. Both have emphasized in interviews that the series opens up the wizarding world far more than the books or films could, giving viewers a broader perspective on events happening beyond Harry’s immediate experience .
Warner Bros Expands Beyond the Series
The Harry Potter franchise expansion goes well beyond the HBO show. Warner Bros has signed a major deal with Hasbro to produce merchandise for the new series and the broader wizarding world .
Hasbro becomes the global primary toy licensee for Harry Potter. The multi-year agreement covers dolls, action figures, collectibles, interactive plush toys, and board games. Tim Kilpin, president of toys and entertainment at Hasbro, said the Harry Potter world aligns perfectly with the company’s mission to deliver play experiences across generations .
Robert Oberschelp, who runs global consumer products for Warner Bros Discovery, pointed out that the timing works well. The first film celebrates its 25th anniversary, and the franchise continues to expand its legacy with one of the most passionate fan communities in entertainment .
This merchandise push comes as Warner Bros Discovery restructures around its core intellectual properties. Harry Potter sits alongside Game of Thrones, DC Comics, and Mortal Kombat as franchises receiving long-term roadmaps for growth .
New Ways to Experience Harry Potter in Theaters and Parks
Fans will not have to wait until 2027 for fresh wizarding experiences. Warner Bros is bringing Harry Potter and the Sorcerer’s Stone back to theaters in a completely new way.
The studio partnered with Cosm, a company that runs “shared reality” venues. These locations feature massive 87-foot screens with over 12K resolution that wrap the film around the entire space. The experience puts viewers inside the magical world .
The immersive version of the first film will play at Cosm venues in Los Angeles and Dallas starting in 2026, with plans to expand to Detroit and Atlanta. Tickets go on sale in early 2026. The venues will serve Butterbeer and Chocolate Frogs to complete the experience. Jeff Goldstein, Warner Bros president of global distribution, said the partnership continues to redefine what the cinematic experience can be for audiences .
This follows similar Cosm releases of The Matrix and Willy Wonka and the Chocolate Factory, which drew strong audience enthusiasm .

Harry Potter Theme Park Expansion in Europe
The wizarding world is also expanding into physical locations. Legoland Deutschland in Bavaria, Germany, will open the world’s first Lego Harry Potter land. Construction takes three years, and the new area will join 68 existing attractions across 11 themed areas .
A Harry Potter themed hotel will accompany the new land, welcoming its first guests in 2026. Each room features design elements representing the four Hogwarts houses: Gryffindor, Hufflepuff, Ravenclaw, and Slytherin. Common areas showcase iconic locations from the series, all built in Lego form .
Fiona Eastwood, CEO of Merlin Entertainments which operates Legoland parks, called this the largest single investment ever made into an existing Legoland site. She said the project raises the bar for creativity and innovation .
The hotel sits within driving distance of major cities, with Munich and Stuttgart each about 90 minutes away by car or train .
Why Warner Bros Is Going All In on Harry Potter
Company executives see the Harry Potter franchise expansion as essential to their future. David Zaslav made clear during earnings calls that Warner Bros Discovery views its intellectual property library as a massive asset. He noted it comes as no surprise that other companies show interest in their portfolio .
The timing matters. As streaming competition intensifies, having exclusive, high-demand content becomes critical. The Harry Potter series gives Max a flagship show that can drive subscriptions for years. Unlike a movie that comes and goes, a seven-season series keeps viewers engaged and paying month after month .
International growth plays a huge role in the strategy. HBO Max launches across Europe on March 26, and having the Harry Potter series in the pipeline gives the platform something no competitor can match. Perrette described the combination of the European launch and the Potter series as bookending a period of massive growth for the company .
The Harry Potter franchise expansion also protects Warner Bros against industry uncertainty. While other studios scramble to build franchises from scratch, Warner Bros already owns one of the most valuable properties in entertainment history. Investing in it now ensures the magic continues for another generation .
