One burning question is what's next for the king of the North, Jon Snow, played by Kit Harington, after his death and resurrection.
"You go straight back to square one. He's still got to rule," Harington told ABC News' Jesse Palmer in an interview on "GMA."
"He's still got this annoying sister to deal with," the actor said, laughing.
Jaime Lannister, the twin brother of Cersei Lannister, who has taken the throne, was last seen in King's Landing after all three of their children died. His stone cold expression at the very end of the finale left a mark on most fans.
"That's the beauty of, of being so blank faced," Nikolaj Coster-Waldau, who plays Jaime, said about his character. "Then people can just read into it. But that's the whole point. I mean, I'm not going to tell you what he thinks. Because then I would give away what happens."
Jacob Anderson said his character, Grey Worm, and the other characters that were with Daenerys Targaryen in Meereen are prepared to arrive in Westeros. "We're here to mess stuff up," he joked. "That's the polite way of putting that."
Not giving too much away about what to expect this season, Indira Varma, who plays Ellaria Sand, kept it short and sweet: "More blood."
The cast members agreed the coming season is one of the strongest yet.
"I thought they were the best scripts that they'd written," said Iain Glen, who plays Jorah Mormont. "And I think what's really good is it's kind of — it feels like it's accelerating towards the endgame, as opposed to any sense of ... treading water."
'Each scene is really vital'
"Each scene is really vital," said Gwendoline Christie, who plays Brienne of Tarth. "The story that's exchanged — this season is so much about the story."
Harington said of the upcoming season, "I think the major difference with this is the pace at which it moves ... It becomes a completely different TV show from the one you've, you've expected."
Anderson lightened things up, joking about what would be a fantastically comical twist.
"We're getting excited about the musical elements as well to the show," he said, laughing. "The dance numbers and the very exciting new direction."
The series has seen 196 deaths so far, which has left many wondering who could be next. The cast members agreed it's a bit shocking that their characters are still around.
The production behind all the choreographed fighting, rage and death is something Anderson said he has sort of struggled with.
"It's really — I don't know about everybody else, but I find it really hard to not do the sound effects. Like, 'Whew. Shew. Boo-book-boo,'" he said. "'No, we'll do that later. Just you concentrate on moves.'"
"It feels like mayhem when you're doing it," Harington said, laughing. "You're just shooting what you can in as much of an order as you can. But you're like, 'This, I don't know how this is going to come together at all.' And then you just you do your best with that. And then you give it over to the experts and the director and the editor, and you see what they produce. And what they produced with the Battle of Bastards was extraordinary."
But the actors admitted they had to prepare for even bigger battles this season.
"I think there are a couple," Harington said without giving away the details, adding that he does not know how things will end.
Many of the cast members think Daenerys will end up on the Iron Throne, but Coster-Waldau proposed another theory.
'I don't think anyone will sit on it.'
"I don't think anyone will sit on it," he said. "I think it will be destroyed."
The season premiere, titled "Dragonstone," first airs on July 16 on HBO.
