As HBO’s Harry Potter series continues production, the original Boy Who Lived has reached out to pass the torch. Daniel Radcliffe recently revealed he sent a personal letter to Dominic McLaughlin, the young actor stepping into those iconic round glasses, and what he shared is both touching and surprisingly grounded.
For someone who spent a decade of his life bringing Harry Potter to the big screen, Daniel Radcliffe has always maintained a healthy distance from his wizarding past. He’s proud of what those films accomplished, sure, but he’s also been clear about moving forward with his career. That’s what makes his gesture toward McLaughlin all the more meaningful—it wasn’t about nostalgia or staying in the spotlight. It was about one actor genuinely looking out for another who’s about to experience something extraordinary.
A letter between two Harrys
During a recent sit-down with Good Morning America, Radcliffe opened up about his connection with the new generation of Hogwarts students. The revelation that caught everyone off guard? He’d already written to his successor. “I sent him a letter, and he wrote back with a really sweet note,” Radcliffe shared, his tone warm but measured.
What he said next really captures who Radcliffe has become since hanging up his wand: “I don’t want to be a ghost in these kids’ lives. I just wanted to tell him to enjoy every moment of it, hopefully even more than I did.” There’s wisdom in that approach—giving space while offering support, acknowledging the weight of the role without adding pressure.
The nostalgia hit Radcliffe hard when he saw the first official images of McLaughlin and the rest of the young cast. “They look so tiny that I just want to hug them,” he admitted with a laugh. “It’s crazy to think I was working at that age.” It’s a reminder that when Radcliffe first stepped onto the Hogwarts Express set, he was just eleven years old, thrust into a phenomenon that would define an entire generation’s childhood.
HBO’s fresh take on a beloved world
HBO’s ambitious series is taking a page from the original film franchise’s playbook by casting relatively unknown young actors in the lead roles. Joining McLaughlin as Harry are Arabella Stanton as the brilliant Hermione Granger, Alastair Stout as loyal Ron Weasley, and Lox Pratt as the sneering Draco Malfoy. The supporting cast includes Alessia Leoni as Parvati Patil, Leo Earley as Seamus Finnigan, Rory Wilmot as Neville Longbottom, and Amos Kitson as Harry’s insufferable cousin Dudley Dursley.
What’s particularly impressive about this production is Warner Bros. ‘commitment to these young performers’ education. They’ve actually built a school at Leavesden Studios so the cast members who are still school-aged can continue their education without interruption. It’s a thoughtful touch that shows they’ve learned from the original films experience—balancing the demands of a massive production with the needs of child actors.
The series is slated to premiere sometime in 2027 on HBO and Max, with each season adapting one book from J.K. Rowling’s seven-novel saga. The big question mark hanging over the project is how they’ll handle the denser, darker entries like “Harry Potter and the Half-Blood Prince” and “Harry Potter and the Deathly Hallows.” Will they stick to the one-book-per-season format, or will those require more episodes to do them justice? Only time will tell, but what’s certain is that this will be HBO’s most expensive series to date.
The beauty of Radcliffe’s letter to McLaughlin is that it represents something bigger than just two actors connected by a role. It’s about understanding the unique pressure and privilege of bringing a beloved character to life, and wanting the next person to have an even better experience. As fans gear up for this new chapter in Harry Potter’s screen legacy, it’s comforting to know that the original wizard is cheering from the sidelines.
