LONDON, May 28 -- HBO has announced the young actors who will play the lead trio in its upcoming TV series adaptation of Harry Potter.

Dominic McLaughlin will play Harry Potter, with Arabella Stanton as Hermione Granger and Alastair Stout as Ron Weasley.

More than 30,000 children auditioned for the roles after an open casting call last year, according to the BBC.

Showrunner Francesca Gardiner and executive producer and director Mark Mylod said, "The talent of these three unique actors is wonderful to behold, and we cannot wait for the world to witness their magic together onscreen."

The trio will join a cast that includes John Lithgow as Albus Dumbledore, Janet McTeer as Minerva McGonagall and Paapa Essiedu as Severus Snape.
