Key Takeaways
- Warner Bros. Discovery should avoid casting original Harry Potter actors in the upcoming HBO series.
- The new series plans to adapt all 7 books faithfully and explore the full depth without movie constraints.
- Bringing back original actors would be distracting, costly, and hinder the series’ ability to appeal to a fresh audience.
Casting for HBO’s new Harry Potter series is well underway, and some fans have already started suggesting that familiar faces from the original films should make an appearance. However, bringing back stars like Daniel Radcliffe, Emma Watson, Rupert Grint, and Tom Felton would be a mistake. Warner Bros. Discovery and HBO should avoid casting these actors in new roles for the upcoming series.
When HBO announced its plans to create a show based on J.K. Rowling’s beloved Harry Potter books, excitement spread quickly among fans—and for good reason. The books captivated readers worldwide and inspired one of the most successful film franchises that sparked the imaginations of countless children and adults. The prospect of a series where each season would be dedicated to adapting one book was especially thrilling, promising a more detailed retelling that wouldn’t be constrained by the limitations of a movie runtime.

Harry Potter’s upcoming HBO adaptation seems to have the confidence of those in control at Warner Bros. Discovery.
While this all sounded promising, the conversation soon shifted to casting, and that’s where the idea of bringing back actors like Daniel Radcliffe, Emma Watson, Rupert Grint, and even Tom Felton surfaced. It’s understandable why fans would feel nostalgic and want to see familiar faces. But involving these actors, even in cameo roles, would come with significant downsides. It would be costly and, more importantly, could distract viewers from the main story, potentially sparking excitement for all the wrong reasons.
So, what’s happening with this Harry Potter series? As of now, details are limited. The series will air on HBO, though no official release date has been announced. It has been confirmed, however, that the show will be a faithful adaptation of all seven of J.K. Rowling’s original Harry Potter books. Unlike the movies, which had to cut content to fit within film constraints, this show will have the opportunity to explore the full depth of the books.
HBO has revealed that each season will cover one book, although the number of episodes per season remains unclear. According to HBO & Max Content Chairman and CEO Casey Bloys, the show “will dive deep into each of the iconic books that fans have continued to enjoy for all of these years.” This means the series could span seven seasons, signaling that HBO and Warner Bros. Discovery are serious about bringing this project to life and will make at least seven seasons in total.
The show already boasts some impressive talent behind the scenes. Succession writer Francesca Gardiner will serve as showrunner, and Mark Mylod, known for his work on Game of Thrones and The Menu, will direct several episodes of the first season. Executive producer David Heyman, who played a significant role in the original Harry Potter films and the Fantastic Beasts series, is also on board. His return marks the presence of at least one familiar face in the Harry Potter production team.
Why Casting Original Harry Potter Stars Is a Bad Idea
Now, back to the main point: why would it be a misstep to cast any of the original actors in this new series? The answer is pretty straightforward. This project needs to carve out its own identity, separate from the movies. Not because the original films were flawed—they were well-received and still hold up today—but because the new series needs to establish itself and appeal to a fresh, younger audience.
Fans of the original movies and books grew up with the story, and now it’s time for a new generation to experience Harry Potter without comparisons to what came before. Daniel Radcliffe was an exceptional Harry Potter, and the original cast brought their characters to life in unforgettable ways. But the time has come to move forward and give new actors a chance to make their mark.
Having actors like Radcliffe, Watson, Grint, Felton, or even Gary Oldman appear in the series would be distracting. The Harry Potter universe isn’t like the Marvel Cinematic Universe—there’s no multiverse to create connective threads between the original films and this upcoming series. The only connection between the two is that they’re based on the same books.
The Cost of Original Actors Would Be Too High
There’s also the financial side to consider. Bringing back the original actors would be expensive. They are now well-established names, commanding significantly higher fees than when they were first cast as young unknowns. Warner Bros. and HBO would have to pay a premium for cameo appearances, and the investment simply wouldn’t pay off. It’s likely the show’s producers understand this already.
Ultimately, the new Harry Potter series needs to forge its own path and capture the magic and wizardry of Hogwarts for a new audience. It should focus on presenting a faithful adaptation of J.K. Rowling’s books without relying on nostalgia or former cast members. Bringing back original actors wouldn’t add meaningful value and could introduce unnecessary challenges for the production team, ones that they wouldn’t appreciate.
