According to the website of Tim Plester, the English actor and playwright will be taking on the role of Black Walder in season three of Game of Thrones.
A veteran of British film and television, Plester will be appearing next year in the historical heist film Closer to the Moon and the Nick Frost comedy Cuban Fury. In 2011, he wrote and co-directed the documentary, Way of the Morris, about the English folk art of Morris dancing. Plester also had a brief but memorable role in Kickass, as the criminal who had an unfortunate encounter with an industrial microwave.
In A Song of Ice and Fire, his character is the great-grandson of Lord Walder Frey. He is called “Black” Walder on account of his hot temper and frightening demeanor, intimidating even his own family.
