They are unquestionably going to be used only as guest stars, and very rarely, but a lot of people like these characters, so I thought I'd make sure they were included.
Mark Mitchinson, who I am unfamiliar with, looks to have the strength combined with everyman feel that is necessary for Tam al'Thor. Tam may not be used much, but he's a very important character, and it will be important for this role to have the right-looking man in it. He looks like Tam to me.
Cenn Buie, the elderly thatcher/trouble-maker, is a memorable role so I decided to cast a somewhat recognizable face in it. Karl Johnson is mostly known for his work on Rome but he's a character actor that can acclimate well to this character.
