Chris Columbus, director of the original Harry Potter films, has lauded HBO's upcoming reboot series as a "spectacular idea," believing its episodic format will allow for a more faithful adaptation of the books. Speaking to People, Columbus explained the limitations imposed by the relatively short runtimes of Sorcerer's Stone and Chamber of Secrets. He noted the team's efforts to include as much source material as possible within the films' two-and-a-half-hour timeframe, but acknowledged inherent constraints.
"I think it's a spectacular idea because there’s a certain restriction when you’re making a film," Columbus stated. "Our film was two hours and 40 minutes, and the second one was almost as long. The fact that they have the leisure of multiple episodes for each book, I think that's fantastic. You can get all the stuff in the series that we didn't have an opportunity to do... All these great scenes that we just couldn't put in the films."
Announced in April 2023, the HBO series promises a "faithful adaptation" of the novels, aiming for a more in-depth narrative than what's feasible in a feature film. Succession producers Francesca Gardiner and Mark Mylod are attached to direct and write, the latter having also worked on Game of Thrones.
Casting is currently underway for Harry, Hermione, and Ron. Regarding the role of Dumbledore, Gary Oldman, who played Sirius Black in the original films, humorously suggested his age might now be suitable for the Hogwarts headmaster, two decades after his Prisoner of Azkaban debut. Mark Rylance is reportedly a top contender for the role, maintaining the original films' focus on British actors. This is perhaps unsurprising given J.K. Rowling's reported involvement in the casting process.
Filming for the Harry Potter TV series is expected to commence in Spring 2025, with an anticipated release window of 2026.
