Yeah, that must have been brutal. Some of the actors let a couple of negative sentences slip during those interviews, but I’m sure they weren’t allowed to.
I don’t know if a single clip shows this better than the reaction of Varys’ actor to his characters death. Just imagine having to sit at a table WITH THE SHITHEADS THAT ARE RESPONSIBLE for butchering an amazing character you should be remembered for, and not being able to say anything. Fuck.
