Best projects: Game of Thrones (2011 – Present, HBO)

The best way we can sum up Jack Gleeson’s impressive acting chops: We want to snuff the kid in the face whenever we see him. Well, to be more specific, his character on HBO’s Game of Thrones, the teenaged king Joffrey Baratheon, he of the many many douche faces, megalomaniacal actions, and all-around unpleasant demeanor.

Gleeson is so convincing as Joffrey that we, like all of his many servants and impoverished minions, would love to throw cow-pies at his mug, and whenever pint-sized badass Tyrion (Peter Dinklage) gives him the Charlie-Murphy-esque slap, we erupt in applause. But, again, that’s all due to the fact that the 19-year-old, real-life dude consistently delivers a ruthless and genuinely cold-blooded performance.

If Joffrey ever meets his maker, we’ll simultaneously clap at the character’s demise and mourn the loss of one of TV’s best pre-legal actors.
