17. The Only Americans
Even though HBO’s Game of Thrones takes place in a fictional fantasy world, nearly 100% of the actors are British, Scottish or Irish. Only three main characters are actually American: Peter Dinklage (who plays Tyrion Lannister), Jason Momoa (who played Khal Drogo), and Pedro Pascal (who played Oberyn Martell aka “The Red Viper”). Yes, Peter Dinklage is American no matter how well he pulls off a British accent and Pedro Pascal came up with his “Dornish” accent all on his own; this can be confirmed during an AmA on Reddit.
