Kit Harington has revealed that he thinks Game of Thrones could have influenced the political landscape as "certain political figures" may have taken their lead from the tyrannical King Joffrey from the show.
The 32-year-old British actor, who plays the much loved Jon Snow in the HBO fantasy series, appeared on The Late Show With Stephen Colbert on Tuesday to discuss reprising his role in the upcoming eighth and final season when it returns next month.
The star mused about the show's influence outside television.
"I got this theory that we kind of screwed the political landscape. I just felt like certain political figures tried to emulate Joffrey and things went a bit wrong."
The much reviled character King Joffrey was played by Irish actor Jack Gleeson to acclaim from 2011 - 2014.
Meanwhile, Harington said he still "can't quite grasp" the level of fame he has achieved since appearing on the show and said the journey has been "extraordinary".
The actor revealed that he has been consistently wrong about predicting about what would happen each season.
He said: "I had theories all along and all of them were wrong. I'm quite glad I never told anyone my theories."
Irish musician Hozier also appeared on the Colbert's late night talkshow and tweeted a picture of himself with Harington. He later performed his track Almost off his new album Wasteland, Baby.
A new trailer for the final season of Game of Thrones dropped on Tuesday and it hints at the dramatic climatic battle between the living and the White Walkers, led by the menacing Night’s King.
