Littlefinger
Okay so, in this case, I am just being nit-picky, but hey, perfection is something that we should all aspire to. Littlefinger is a very despicable character and Aidan Gillen plays it with finesse but one wonders why his hair is so grey, he is just 30 after all- in the books. But books mention that he started aging prematurely. The problem with Lord Baelish’s portrayal is that he is supposed to be shorter in the books and have a pointy beard. Martin writes, “Petyr had been a small boy, and he had grown into a small man, an inch or two shorter than Catelyn, slender and quick, with the sharp features she remembered and the same laughing grey-green eyes. He had a little-pointed chin beard now, and threads of silver in his dark hair, though he was still shy of thirty.” Well, maybe we can forgive this small discrepancy.
