The Harry Potter remake has cast another key character for the TV adaptation, but their appearance suggests a change compared to the books and movies. The upcoming Harry Potter TV show has already cast several key characters from the books, including Harry (Dominic McLaughlin), Ron (Alastair Stout) and Hermione (Arabella Stanton). Adult characters cast as of writing include Snape (Paapa Essiedu), Dumbledore (John Lithgow), Professor McGonagall (Janet McTeer), and Hagrid (Nick Frost). All of these characters are vital to the story of the first book, Harry Potter and the Sorcerer’s Stone, each having a role in the narrative.
