For those who don't know, Joffrey Baratheon (Jack Gleeson) is a spoiled, egotistical, vengeful and sadistic king who was once considered the worst villain of the show.
Harington chimed in on Trump too, saying "I believe in experts… Mr. Donald Trump — I wouldn't call him 'President,' I'll call him 'Mister.' I think this man at the head of your country is a con artist."
"Thrones can be used as a metaphor way too much, but if there's one truth, I think, it's that people who really desire power are the people who shouldn't have it," Harington said.

"Game of Thrones" kicks off its second-to-last season July 16, and for Harington that means looking forward to playing roles other than the one he made famous as "Jon Snow."
"Maybe I can reinvent myself and get away from an image that's so synonymous with Thrones," Harington said. "But maybe this was the role I was always meant to play and that was it."
Though Harington does have a few upcoming roles, he says he will enjoy laying low after the series ends.
"I'll enjoy the madness quieting a bit, I'd like a few years of relative obscurity."
