'Game of Thrones' Star Kit Harington Defends Red Viper Casting: Pedro Pascal Will Be Brilliant

"Game of Thrones" may not return until next year, but production on HBO's hit show is underway.

"We are very near the start," Kit Harington (Jon Snow) told Yahoo! TV at the Young Hollywood Awards on Thursday. "We shoot July through December. We've just started and have a long way to go. Everyone's extremely nervous because we've got a lot to do. Everyone is always nervous at this stage every year and we always get it done."

It seems like "GoT" Season 3 would be hard to top (we still have tissues on standby for when the Red Wedding creeps up in conversation), but Harington says Season 4 will blow our minds.

"I've got great hopes for this season. I've read it and it's fantastic," he told us. "You're going to love it. It's my favorite so far."

One major new character addition this season is bad boy Oberyn Martell, aka the Red Viper. It was announced last month that Chilean actor Pedro Pascal had nabbed the role, which sparked controversy among fans.

"Thrones" creator George R.R. Martin defended the decision; and Harington, too, fully has faith in the casting.

"I haven't seen him in costume yet, but I have had dinner with him a couple of times. He's a lovely man," Harington explained. "He's going to be brilliant. It's an amazing character and quite the story line. You're going to enjoy it. [Fans] won't be disappointed, Pedro Pascal is the man for the job."

While Harington was tight-lipped on what Jon Snow is going to be up to next year, he revealed where he would like his character to go.

"Well I do know where he goes…" Harington teased. "I'd like him to go and rescue Arya, but I don't think he's going to be able to. I'd like to see him collect Sansa, Arya, and Bran and just take them to the wall or something."

And Harington doesn't exactly have high hopes romantically for Jon this year.

"Yeah, I've ruined that," he laughed, talking about Ygritte (played by Rose Leslie).

How about a romance (or at least a scene this season) with the Mother of Dragons herself, Daenerys (Emilia Clarke)?

"I don't know…" Kit smiled. "You know, we're either going to fight or, well, the opposite."

We're definitely voting for option two.

"Game of Thrones" Season 4 will premiere in spring 2014.
