The cast of HBO's Harry Potter series continues to expand as Nick Frost is in talks to play Rubeus Hagrid, reports Deadline. The series adaptation of JK Rowling's novels was announced in 2023.

Portrayed by the late Robbie Coltrane in the film series, Rubeus Hagrid is a half-giant who is the gamekeeper of the wizarding school Hogwarts.

Earlier John Lithgow confirmed he will play Albus Dumbledore, the headmaster of Hogwarts. Janet McTeer is in negotiations to portray Professor McGonagall, the transfiguration professor at Hogwarts, with Paapa Essiedu in talks to play Professor Snape, the potions master at Hogwarts.

Meanwhile HBO said the following in a statement, “We appreciate that such a high-profile series will draw a lot of rumour and speculation. As we make our way through pre-production, we will only confirm details as we finalise deals.”
