- Years Active: Around 2020–present
- Known for: Grow (2025) and the BBC TV adaptation Gifted (2025).
The titular role of the boy who lived will be played by Dominic McLaughlin, previously played by Daniel Radcliffe.

She played the role of Matilda Wormwood in Matilda the Musical and has trained at Guildford School of Acting, British Theatre Academy, and Aldance.
3. Alastair Stout as Ron Weasley
- Birthday: Born around 2014 (age approximately 11 in 2025)

Alastair Stount will play the role of Harry Potter’s best friend, Ron Weasley. The role was previously played by Rupert Grint in the movies.

Interestingly enough, the role of Albus Dumbledore is played by two actors in the movies. Richard Harris was closer to the Dumbledore we read in the books. He played the role up until 2002. However, he sadly passed away on 25 October 2002, after which the role was taken up by Michael Gambon, who brought his own quirky energy to the character. It was something very different from the Dumbledore we know and love from the books.
This time around, John Lithgow will be stepping into the shoes of the character. Lithgow is an Oscar-nominated actor known for films like Footloose, Interstellar, Rise of the Planet of the Apes, and Killers of the Flower Moon.

Nick Frost will be playing the role of the compassionate giant Hagrid. Previously played by Robbie Coltrane, who sadly passed away in 2022, Hagrid is one of Harry Potter fans’ favorite characters owing to his fun and loving nature. He has always been an integral part of Harry’s life, and his role in the first three movies is even more prominent than the others.
While fans might have been envious of the other castings, this role was welcomed with open arms by Potterheads. Frost is an English writer and comedian and is known for his impeccable comedic timing in films like Shaun of the Dead, The World’s End, and Hot Fuzz. He even played the role of Gobber in the new How to Train Your Dragon live-action remake.
