3. Peter Dinklage as Potato Creek Johnny Perrett
Johnny Perrett would eventually become famous in the late 1920s for finding the biggest gold nugget ever and reigniting the mining boom in the Black Hills. Until then, he was mostly known as a local fixture searching for his fortune. He was also 4 feet 3 inches tall, which was fairly memorable back then. While history smiles on "Potato Creek Johnny," the tendency for the HBO show to tear down legends would probably come through here. Just as Wyatt Earp was portrayed as a carpetbagger thug and Wild Bill Hickok was a jaded misanthrope, Johnny would be interesting as a duplicitous bottom-feeder.
Enter Peter Dinklage, who not only has experience playing underestimated strategic minds, but also can enter the role of a dead-eyed sellout with no morals to hold him back. Some may think I'm talking about his character in X-Men: Days of Future Past, but I could also be taking a slight shot at him for his monotone vocal work on Destiny. Or neither. You decide!
Still, Dinklage is an incredibly versatile performer, able to pontificate on the capability of dragons in politics on "Game of Thrones," express a profound and real sense of loneliness in The Station Agent, and don a mullet wig and collect a paycheck for Pixels. I would not stop smiling if his precise delivery of George R.R. Martin's dialogue were applied to "Deadwood" and its trademark syntax.
