Jason Isaacs Says HBO’s Harry Potter Series Will Shock Fans Despite Early Criticism Based on Set Photos

Jason Isaacs, who played Lucius Malfoy in the original Harry Potter films, has spoken out about HBO’s upcoming Harry Potter series, promising that fans are in for a fresh take on the beloved franchise.

In an interview with Entertainment Weekly, Isaacs praised Johnny Flynn, the actor stepping into the role of Lucius, and expressed confidence that Flynn will bring his own unique energy to the character.

“Johnny will do his own thing. Maybe he’ll be more charming. I doubt that he’ll look like me, because that was the look I came up with and he’s far too original to want to copy anything,” Isaacs said.

Isaacs went on to emphasize that the HBO series will be very different from the original films. He described the show as a Harry Potter for a “new generation,” with redesigned sets, updated costumes, and scripts that expand each book into an entire season.

“They’re redesigning everything from scratch. They’re redesigning Hogwarts and the costumes and they’re writing all these fabulous new scripts that are expanding each book into whole season. And it’ll be fab — it’ll be for a new generation. It’ll be their version of Harry Potter,” he added.

Despite Isaacs’ enthusiasm, the first glimpses of the show have sparked mixed reactions online. When Warner Bros. released the first official look at Nick Frost as Hagrid, fans had a wide range of responses.

Some praised Frost’s portrayal, but others felt the look was off and compared it to cosplay rather than the iconic character. Similarly, Paapa Essiedu, cast as Severus Snape, faced criticism for not matching the traditional description from the books.

Media outlets like The Mail and The Telegraph highlighted that Essiedu’s casting as a Black actor has drawn negative attention from some fans fixated on “book accuracy,” along with broader discussions about diversity in casting.

Arabella Stanton, cast as Hermione, also encountered backlash when her casting was revealed. Many comments on social media questioned her ethnicity, despite her being English-born.

The conversation around her casting was so intense that “Arabella Stanton ethnicity” trended on Google shortly after the announcement. HBO, aware of the growing negativity, removed the racist comments from the posts and disabled further commenting to prevent harassment of the young actors.

Isaacs, however, remains optimistic about the series and the cast. He believes the new actors will bring fresh energy to the story and encourages fans to approach the show with an open mind. “It’s going to be for a new generation. It’s their version of Harry Potter, and I think they’re going to do a fantastic job,” he said.

The HBO series, which is expected to run for several seasons, aims to honor the spirit of J.K. Rowling’s books while giving each story more room to breathe than the original films allowed.

Fans can expect familiar characters and magical worlds, but with new interpretations, expanded narratives, and a modern sensibility that may surprise longtime enthusiasts.

Isaacs’ comments underline the series’ goal: to offer a bold, creative vision while respecting the legacy of the original films, even as it navigates controversy over casting choices and visual design.

While reactions have been mixed, the series promises to be a major talking point for both Harry Potter fans and new viewers when it premieres.
