FACT#83: And so are the accents
Game of Thrones contains quite a mix of British accents, some authentic, some decidedly less so. The Northern tones of Rose Leslie, who plays Ygritte, are adopted for the show: in real life, Leslie has a distinctly "upper class" voice. The Irish actor Michael McElhatton hides his real accent and puts on an appropriately sinister, almost RP voice to play Roose Bolton. Carice van Houten, who plays the red Priestess Melisandre, has to hide her native Dutch accent to play the character, while Peter Dinklage, who plays Tyrion Lannister, tries his best to sound British in the show, despite the fact that he's actually American. The best accent of all, of course, belongs to Aiden Gillen, who plays Littlefinger. It can best be described as "all over the place", as if he's been told not to use his native Irish accent, but can't stop it creeping back in.
