Credit: Warner Bros.HBO’s upcoming Harry Potter television series has finally revealed the actors who will play the franchise’s iconic trio, Harry Potter, Ron Weasley, and Hermione Granger.
The long-awaited news follows a major announcement from a few weeks ago that saw six actors fill several other major roles: Paapa Essiedu (Black Mirror) as Severus Snape, John Lithgow (Dexter) as Albus Dumbledore, Nick Frost (Shaun of the Dead) as Rubeus Hagrid, Janet McTeer (Tumbleweeds) as Minerva McGonagall, Luke Thallon (Tom Stoppard’s Leopoldstadt) as Quirinus Quirrell, and Paul Whitehouse (Harry & Paul) as Argus Filch.
Now, HBO has officially announced that it has found the successors to Daniel Radcliffe, Rupert Grint, and Emma Watson, who played Harry Potter, Ron Weasley, and Hermione Granger respectively in all eight films.
Per Variety, Dominic McLaughlin will play Harry Potter, Alastair Stout will take on the role of Ron Weasley, and Arabella Stanton will step in as Hermione Granger.
It is reported that over 30, 000 actors auditioned for the series’ three leads since HBO’s open casting was launched late last year. The three new actors are shown in a tweet below:
