Credit: Warner Bros.HBO’s upcoming reboot of Harry Potter is taking no chances when it comes to the safety of its cast.
First announced in 2023, HBO is currently in the process of re-adapting JK Rowling’s books into a long-form TV series. With one season per book, the second take on the wizarding world is set to delve deeper into the source material, as well as flesh out other storylines and characters that have sparked fan interest over the years.

Filming officially began last summer, with HBO recently unveiling a first look at Dominic McLaughlin in the lead role. Warner Bros. Discovery is also set to release the show’s first footage today, as early reactions to the initial image have created cautious optimism among fans.
Some viewers have already drawn comparisons to the visual style of Alfonso Cuarón’s Harry Potter and the Prisoner of Azkaban (2004), a film often regarded as one of the strongest entries in the series.
However, not everyone is sold on the idea of a Harry Potter reboot.
Fan Backlash Triggers HBO to Ramp Up ‘Harry Potter’ Set Security
Fan backlash has largely centred on J.K. Rowling, who has become a prominent and controversial figure in debates around transgender issues in the years since the franchise concluded with Harry Potter and the Deathly Hallows – Part 2 (2011).
The decision to produce a second adaptation so soon after the original films has also faced scrutiny, particularly as early elements of the series appear to echo the films closely. That includes Nick Frost being cast as Rubeus Hagrid, familiar design choices for Diagon Alley, and the return of Warwick Davis as Filius Flitwick.
Some fans have also criticized certain casting choices. The decision to cast Paapa Essiedu as Hogwarts potions master Severus Snape triggered particularly heated discussion due to the fact that the character was written as white.
Essiedu – who is also considerably younger than his predecessor, Alan Rickman – recently addressed the racist backlash, revealing that he’s received violent threats online.
“I’ve been told, ‘Quit or I’ll murder you,'” Essiedu told The Times. “The reality is that if I look at Instagram I will see somebody saying, ‘I’m going to come to your house and kill you.'”
Essiedu quipped that he’s “pretty sure” he’s not going to be murdered, but noted that this comment could “age badly.” He also insisted that “nobody should have to encounter this for doing their job.”
“Many people put their lives on the line in their work. I’m playing a wizard in Harry Potter,” he said. “And I’d be lying if I said it doesn’t affect me emotionally.”
Amid the violent threats, HBO has reportedly tightened security on the Harry Potter set. HBO CEO Casey Bloys told Variety that the production has a “serious security team.”
While Bloys didn’t mention Essiedu by name, he elaborated on the backlash to Harry Potter casting news.
“With all actors on any kind of big IP shows — and this is obviously one of those where you’ve got, you know, passionate fans, people with a lot of opinions — it can get scary in places,” Bloys said. “So for any show like that, we anticipated it and tried to have training, you know, best practices in terms of social media and how to handle it. And obviously, we’ve got a serious security team. So unfortunately, it was something that we thought might happen and we just try to be as careful as we can.”

Notably, recent reports also suggested that bullying is rife among the younger cast members on set of the Harry Potter reboot.
Paapa Essiedu’s Stance on JK Rowling
Adding another layer of online discussion to the decision to cast Paapa Essiedu as Snape is the fact that the actor actively disagrees with JK Rowling’s outspoken views on gender identity.
In 2025, Essiedu was one of hundreds of TV and film professionals to sign a letter calling for industry action on trans rights. While some theorized that this could threaten his future on the show, for which Rowling is an executive producer, an insider later told MailOnline that Rowling would “not be bothered one iota by Essiedu’s decision – and wouldn’t dream of intervening to get him sacked, despite being heavily involved in the project.”
Rowling herself commented on the matter on X, formerly Twitter.
“I don’t have the power to sack an actor from the series, and I wouldn’t exercise it if I did,” Rowling wrote. “I don’t believe in taking away people’s jobs or livelihoods because they hold legally protected beliefs that differ from mine.”

HBO has actively sought to distance itself from Rowling’s views, with Bloys repeatedly stressing that they do not impact Harry Potter.
“The decision to be in business with J.K. Rowling is not new for us,” Bloys said on The Town with Matthew Belloni podcast. “We’ve been in business for 25 years. We already have a show on HBO from her called C.B. Strike that we do with the BBC.”
He added, “It’s pretty clear that those are her personal, political views. She’s entitled to them. Harry Potter is not secretly being infused with anything. If you want to debate her, you can go on Twitter.”
