Game of Thrones cast predict 'shocks' at the world premiere

Cast members of the fantasy drama including Kit Harington, Gwendoline Christie, Sophie Turner and Alfie Allen attended the launch of the new season at the Tower of London in the capital, ahead of its debut on Sky Atlantic in April.

The fans of the blood-and-bosoms fantasy epic also looked like they were having a lot of fun.

Hundreds of fans watched as fires burned around the tower, alongside a giant projection of a live stream featuring interviews with the cast and helicopters flew overhead.

Alfie Allen, who plays Theon Greyjoy, said there will be “shocking scenes without a doubt”.

The 28-year-old actor added: “I’d like to see how much farther they can push the sort of dark side of it as a show as a whole.”

Allen – the younger brother of singer Lily – said there is “maybe a little bit of light at the end of the tunnel” for his character.

“It’s done in a very clever way,” he said.

Nikolaj Coster-Waldau, who portrays Jaime Lannister, added: “This season we are getting into the end game of this story so some of the major storylines start to overlap.

“I think that’s going to be most exciting for fans of the show.”

Michael McElhatton, who plays Roose Bolton, teased this season could bring some shockers to fans of George R R Martin’s books.

“The world has just got bigger and bigger and we are going to move into the world towards Dorne a lot more and introduce a lot of new characters there,” he said.

“There’s a lot of shocks particularly for the book readers. There are things that happen now that aren’t in the books.”

Dean-Charles Chapman, who portrays young king Tommen, agreed.

“(It’s going to be) shocking. Tommen does get married but in the world of Game Of Thrones, things don’t turn out quite right,” he said.

“I don’t even know what’s going on now. It’s so confusing. There are so many characters and so many story lines.”

Kit Harington, who plays Jon Snow, brushed off any controversy surrounding the show.

The programme has made headlines for scenes showing Ned Stark’s beheading in the first series, the Red Wedding in season three and Cersei’s rape by her brother Jaime.

He defended the “violent” scenes, saying: “I think it’s what makes our show our show and I don’t think it’s controversial for the sake of it.

“When women are nude in it it’s used for a reason. When people are brutally killed in it there’s usually consequences. I think it’s good.”

The 28-year-old star, who has had roles on films like Testament Of Youth and Pompeii, said he thinks the show could go on for seven or eight seasons.

Asked why it is such a success, he said: “It’s complex and it doesn’t treat audiences like idiots.”

The new series of Game Of Thrones begins on April 13 on Sky Atlantic.
