Harry Potter Cast: New Generation Takes Centre Stage as HBO Series Production Begins

A New Era for the Wizarding World

The Harry Potter cast is making headlines as production has now started on the new television series, with principal photography beginning in July 2025 at Warner Bros. Studios Leavesden. This marks a significant moment for fans worldwide, as a new generation of actors prepares to bring the beloved characters to life on the small screen.

Meet the New Trio

Young actor Dominic McLaughlin will star as Harry Potter, the Boy Who Lived, the role that launched Daniel Radcliffe to global fame. Alastair Stout will play Ron Weasley and Arabella Stanton is the new Hermione Granger. HBO auditioned more than 32,000 children for the lead role, with the casting team reviewing between 500 and 1,000 audition tapes per day.

Star-Studded Supporting Cast

The series has assembled an impressive ensemble of established actors. John Lithgow will portray Albus Dumbledore, Paapa Essiedu as Severus Snape, and Nick Frost will play Hagrid. Additional casting includes Katherine Parkinson as Molly Weasley, whilst Lox Pratt and Johnny Flynn will play Draco and Lucius Malfoy respectively.

Where Are the Original Cast Now?

It’s hard to believe it’s been 24 years since the first film hit the big screen in 2001. Daniel Radcliffe, now 36, has taken on a range of projects including The Woman in Black, Swiss Army Man, and Weird: The Al Yankovic Story. Radcliffe recently revealed that he sent a letter to Dominic McLaughlin, who is taking over the role for HBO’s reboot.

Looking Ahead

Harry Potter is scheduled to premiere on HBO in the United States in early 2027, with the first season consisting of eight episodes. The series will be a faithful adaptation of the beloved Harry Potter books by author and executive producer J.K. Rowling. For devoted fans and newcomers alike, this reimagining promises to bring fresh magic to the wizarding world whilst honouring the legacy that made Harry Potter a global phenomenon.
