Nikolaj Coster-Waldau, Game of Thrones
There are so many characters currently traversing Westeros, you'd need an Iron Islands armada for the principals alone. Thankfully, after wading in the water for what felt like years, some of our favorites -- Sansa, Cersei, Jon Snow, Daenerys, Tyrion -- proactively rose to the top of Season 6. Jaime Lannister's role... wasn't as glamorous, with the Kingslayer perpetually showing up late to the action. But shout out to Coster-Waldau, who excels in tinier moments, be it a flirtatious encounter with Brienne, gruff intimidation against Walder Frey, or walking in on his sister-lover's coronation. You know tragedy will befall Jaime one day, and you know it because Coster-Waldau dredges up history every time he walks onscreen.
