Julian Glover plays the role of the cunning, deceptive, and outright loathsome Grand Maester Pycelle who kicks off the show's central conflict between the Lannisters and Starks in “Game of Thrones.” Surprisingly Glover is also the voice behind Hagrid's monstrous pet spider, Aragog in "Harry Potter and the Chamber of Secrets."
