'Game Of Thrones's' Jon Snow Is In Very Dangerous Territory, Kit Harington Says (VIDEO)

"Game of Thrones" is only five days away from its Season 3 premiere and Kit Harington, who plays Jon Snow on the series, says things are about to get hairy.

"It's kind of a complex season for him. He's got more freedom than he did last season in a weird sort of way, but he's under the cosh," Harington explained on HuffPost Live (above). "He's in very dangerous territory."

The actor, who says he could've never foreseen being on such a wildly popular HBO series, was tight lipped about spoilers. As for the mystery of Jon Snow's mother, Harington teased that he knows who he wants it to be, but he doesn't know who "Game of Thrones" author George R.R. Martin has in mind. "I hope I find out one day," Harington said.

The actor does what he can to ensure Jon makes it to the end of "Game of Thrones." "You have to be really nice to George when you see him, in case he writes you the worst death ever," Harington joked.
