Now that HBO's Harry Potterhas cast their Professor Quirinus Quirrell, hopefully the TV show can expand on his character in a way that the book and movie never did. Set for release in 2026, Harry Potter season 1 will delve into the first book of the series, Harry Potter and the Sorcerer's Stone. As readers will remember, this installment sees Harry discovering he is a wizard, going to Hogwarts for the first time, and getting sucked into a conspiracy surrounding the Sorcerer's Stone, which grants eternal life. In the middle of this scheme is the nervous Professor Quirrell.
