Rupert Grint made being the third wheel at Hogwarts an art form. His Ron Weasley delivered spectacular facial expressions, heroic loyalty, and enough nervous energy to power an entire fleet of enchanted Ford Anglias. Across eight Harry Potter films, the red-haired wizard grew from a terrified first-year into the beating heart of the Golden Trio.

Now the Sorting Hat has another generation to worry about. HBO is preparing a fresh adaptation, with Alastair Stout inheriting Ron's wand, robes, and considerable spider-related trauma. And Grint has sent his young successor something wonderfully old-fashioned.

A letter filled with encouragement.

Passing the wand comes with emotional baggage, especially when that wand helped define an entire childhood. Speaking to the Entertainment Tonight, Rupert Grint revealed that he wrote to Stout before cameras started rolling.

"I wrote him a letter, before they started, passing the baton as it were," he explained. The message contained a simple wish.

"I had so much fun stepping into this world, and I hope he has the same experience." he revealed to Entertainment Tonight.

The subject also resurfaced amid questions about the upcoming HBO adaptation and possible appearances by the original cast. Grint has yet to announce a cameo, although his message to Stout has already provided a heartwarming connection between the two generations.

He described watching the casting cycle restart as strange, recalling the moment he, Daniel Radcliffe, and Emma Watson entered the wizarding world. Grint even noticed a family resemblance between himself and Stout. Apparently, the Weasley genes are maintaining an impressive casting record.

One generation has passed the torch. Christmas is about to reveal what the new Gryffindors do with it.

HBO's eight-episode Harry Potter and the Philosopher's Stone premieres December 25, 2026, on HBO and HBO Max. The series begins with Harry's arrival at Hogwarts, where magical lessons, dangerous secrets, and one extremely questionable school security policy await.

McLaughlin leads as Harry, Arabella Stanton plays Hermione Granger, and Stout completes the trio as Ron. John Lithgow portrays Dumbledore, Janet McTeer plays McGonagall, Paapa Essiedu becomes Snape, Nick Frost steps into Hagrid's enormous boots, and Lox Pratt plays Draco Malfoy.

The series has already secured a second season adapting Chamber of Secrets. Kit Harington joins as Gilderoy Lockhart, with Rafe Spall as Arthur Weasley, Billy Barratt as Tom Riddle, Lenny Rush as Dobby, and Bonnie Hill as Ginny Weasley among the announced additions.
