Harry Potter TV series casts actors for Snape and Dumbledore

The Harry Potter series has cast actors for several key roles:

Albus Dumbledore - John Lithgow; Minerva McGonagall - Janet McTeer; Severus Snape - Paapa Essiedu; Rubeus Hagrid - Nick Frost; Professor Quirrell - Luke Tallon; Argus Filch - Paul Whitehouse.

The series is being developed by showrunner Francesca Gardiner, who will direct multiple episodes for HBO in association with Brontë Film and TV and Warner Bros. Television.

The streaming service is marketing the series as a "faithful adaptation of the beloved Harry Potter book series" by J.K. Rowling, who is also an executive producer.

Fans can expect a new cast and a deep dive into the Harry Potter book world. Rowling notes that the series will reveal storylines and details that could not be included in the films due to limited running time.

The creators promise to remain faithful to the books, while at the same time want to present Hogwarts in a new light, including previously unseen locations, such as the staff room.
