Daniel Radcliffe has revealed that he sent a private letter to Dominic McLaughlin, the 11-year-old newcomer cast as Harry Potter in HBO’s upcoming television adaptation, offering encouragement as the child actor steps into one of the most scrutinised roles in contemporary pop culture. Radcliffe discussed the note during an appearance on Good Morning America, remarks first reported in detail by Deadline and later expanded on by other outlets.
Radcliffe said he wrote to McLaughlin simply to wish him joy on the job, telling him he hoped he would have an even better experience than the decade Radcliffe spent making the original films. The actor added that he does not want to “hover” over the new generation, stressing that the series should belong to them and reiterating that he has no plans to appear in the show, which producers have framed as a creative clean break from the movies. McLaughlin replied with what Radcliffe described as a very sweet note, establishing a quiet line of support between the two performers.
The HBO series, now in production and aiming for a 2027 launch, will adapt each of J.K. Rowling’s seven novels across multiple seasons, with Francesca Gardiner as showrunner and Mark Mylod set to direct key episodes. Casting directors selected McLaughlin, Arabella Stanton and Alastair Stout as the new Harry, Hermione and Ron after auditions that drew tens of thousands of hopefuls worldwide, while a separate ensemble of established actors will play the adult roles. Rowling serves as an executive producer and has said she worked closely with the writers’ room, praising early scripts in public posts.
McLaughlin’s casting, however, has unfolded against a fraught backdrop. Soon after his name was announced, the young actor became the target of online abuse, with some critics fixating on details such as his eye colour and others directing anger at Rowling’s record on transgender issues toward the show’s child leads. Commentators have warned that the culture-war battles surrounding the franchise could place heavy pressure on its young stars, even as Warner Bros. and HBO continue to defend Rowling’s involvement and highlight the commercial strength of the brand.
Radcliffe has previously aligned himself with fans and cast members who support transgender rights, creating a striking contrast with Rowling’s public stance. His decision to reach out privately rather than attach himself to the production allows him to reassure McLaughlin while keeping some distance from a reboot that remains both a major bet for HBO and a flashpoint in ongoing debates around the Harry Potter legacy.
