Nick Frost is set to play Rubeus Hagrid in HBO’s new Harry Potter series, stepping into the role previously portrayed by the late Robbie Coltrane. Frost aims to honor Coltrane’s legacy while exploring Hagrid’s complex personality, emphasizing that he will not mimic the original performance but will bring a unique perspective to the character. The series, directed by Mark Mylod and featuring other key actors like Dominic McLaughlin as Harry and John Lithgow as Dumbledore, will adapt one book per season for deeper storytelling.
