'Game of Thrones' Cast on Season 4's OMG Moments: 'There Is Not an Episode That's Dull,' 'People Are Going to Be (Un)Happy'

"Game of Thrones" fans have come to expect a huge OMG moment in Episode 9 of every season — Ned Stark's beheading, the Battle of Blackwater, the Red Wedding. But all bets are off now; according to the stars on the red carpet, it's mayhem throughout.

If you try to talk about the show with people who have read the books or the scripts, there's a peculiar rhythm of weird pauses in their speech as they try to talk around spoilers that's very evident in the video above. Think back to conversations you had before the Red Wedding; they probably went a lot like this. Odds are good even book fans are going to be surprised with the way things are handled this season.

Sophie Turner (Sansa Stark): "Game of Thrones" is sex, it's violence, it's incest — there's going to be plenty, trust me.

Lena Headey (Cersei Lannister): It's kind of like we've been climbing the roller coaster, and now the craziness and the darkness and the real struggle begin.

Peter Dinklage (Tyrion Lannister): It wouldn't be our show without an "Oh, my God" moment or three or four. Yeah, we don't disappoint. It's probably going to get to a point where people are going to expect an "Oh, my God" moment every season, and if we don't do one, we're going to be killed. But no, there's plenty more. And it's done very, very gracefully this season.

Maisie Williams (Arya Stark): This is the thing about the new season, is that we do not just have a big finale with mayhem. This year, it's throughout. There is not an episode that's dull or slower than any other. There is something jam-packed in every single episode.

Emilia Clarke (Daenerys Targaryen): I think there's going to be some things that people are going to be happy about, and there are some things people are going to be very unhappy about.

Sibel Kekilli (Shae): There are going to be some changes. Maybe good people are going to change to a bad way, and bad people maybe to a good way.

Reporter: How much more provocative is this next season going to be than the last season?

Clarke: It's taking it to a different stage now in that it's not only visually provocative, but it's also now becoming content provocative as well.

Dinklage: Yeah, some of the things that some of these actors do is pretty risqué, and God bless 'em. It will continue to push those envelopes and be provocative. In many different ways.

Aidan Gillen (Littlefinger): I didn't think it could get much more provocative than some of the stuff we've seen. I think it would get dull if it were just trying to be sensational for the sake of it and being provocative for the sake of it.

"Game of Thrones" Season 4 premieres April 6 at 9 p.m. on HBO.
