The new Boy Who Lived, Dominic McLaughlin, recently called the moment he received a personal letter from original Harry Potter star Daniel Radcliffe an “insane” and unbelievable experience.
McLaughlin is stepping into the incredibly iconic role for the upcoming HBO TV series, taking on a part that Radcliffe played for over a decade in the blockbuster film franchise. The passing of the magic wand, or in this case, a pen, is a heartwarming moment of support from one generation of the Wizarding World to the next.
McLaughlin, who is just 11 years old, recently shared the details of receiving the note during an interview on a British TV show. The new Harry Potter actor is clearly excited about the series and receiving such a personal sign of approval from his predecessor.
Let’s break down the details of this touching celebrity exchange.
McLaughlin was traveling home on a train to Glasgow when his dad handed him the surprise note, which made the reveal even more of a shock.
He was traveling after a day of filming the highly anticipated series when the envelope was passed to him. It’s a sweet, low-key way for the momentous exchange to happen, far away from the cameras and glitz of a premiere.
The young star said he didn’t fully understand the letter’s significance until he finished reading it. He mentioned that he got to the bottom and saw the simple, recognizable signature of the film icon. McLaughlin admitted he was “going mad” with excitement after seeing the signature but had to “keep cool” because he was surrounded by other passengers on the train.

Daniel Radcliffe revealed that he intentionally reached out to the new star to wish him well and offer solidarity for the immense journey ahead.
He has been open about the unique pressures and experience of essentially growing up in the spotlight of such a massive global phenomenon. The former Harry Potter star has consistently shown a protective concern for the new cast.
Radcliffe told Good Morning America that he was careful not to be “a specter” in the lives of the new children taking on the iconic parts. He simply wanted to offer a positive word of encouragement and support to the 11-year-old actor. Radcliffe stated his main hope was for McLaughlin to “have the best time, and an even better time than I did.”
The original Harry Potter actor confirmed he even received a very sweet thank-you note in return from McLaughlin. Radcliffe said that when he sees photos of the young cast, he just wants to hug them because they seem so young. He expressed how “crazy” it feels that he was doing the same exact thing at that age, adding that the situation is also “incredibly sweet.”
McLaughlin has shared nothing but positive updates about his experience on the set of the new HBO TV series, which began production in July.
The show is currently filming at Warner Bros. Studios Leavesden, which is the same location where all eight of the original Harry Potter films were made. This continuity is surely a magical connection for both the cast and the franchise’s dedicated fans.
The young actor has stated that filming is “going amazing” and “really well.” Being part of such a huge production can be daunting, but McLaughlin seems to be taking it all in stride. He happily reported that he has already “made good friends with everyone” and that it is “great to be there” on set. His enthusiasm is a great sign for the chemistry fans are hoping to see among the new Golden Trio.
Yes, the supportive gesture from the original cast seems to have extended beyond just Harry Potter himself.
Rupert Grint, who famously played Ron Weasley in the film series, also confirmed that he reached out to the new Ron, Alastair Stout. This full-circle moment ensures the young stars know they have the full support of the actors who came before them.
Grint said he wrote Stout a letter before filming started, effectively “passing the baton, as it were.” He wished the young actor all the best and shared his hope that Stout would have a similar experience to the one he had. Grint confessed that having the cycle happen again is “quite strange” but that he is genuinely “really intrigued” to see how the new show plays out.
His support, alongside Radcliffe’s, is a touching demonstration of the lasting impact the original films had on their cast.

The new Golden Trio is rounded out by Arabella Stanton, who is playing Hermione Granger. All three young stars were cast after an extensive open casting call that saw over 32,000 children audition for the roles. The new HBO series, which is a faithful adaptation of J.K. Rowling’s books with each season covering one novel, is currently slated to premiere in 2027.
With the original cast offering their blessings, anticipation for this new era of the Wizarding World is only building. The support from the first generation is a beautiful way to welcome the new one.
