Littlefinger — Edward Norton
This one is as good as it gets. Littlefinger is as conniving as they come. Between his web of lies, numerous betrayals and general creepiness, Littlefinger made sure he left an impression on everyone that he interacted with. Picturing Ed Norton as Littlefinger is almost too perfect. He already has the proper haircut, he has excelled playing the role of a dishonest individual multiple times, and he is a tremendous actor. Norton would take Littlefinger to the next level.
