The Game of Thrones cast played a game of “Game of Thrones Sword or ‘80s Metal Band” for charity and … they didn’t do that great. Maybe they don’t watch the show as closely as Game of Thrones superfans. Which is fine. Right? They probably have better things to do? As long as they’re good actors, I guess it shouldn’t be a requirement to be a huge Game of Thrones nerd who knows every obscure piece of trivia about the show? Or maybe they don’t even GAF about watching their own show, Maggie Smith-style.
