The stars of Game Of Thrones promised plenty of shocks as they took in a royal setting for the world premiere for the show's fifth series.
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, ahead.
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 reprises his role as Roose Bolton, teased fans of George RR Martin's books will be in for some surprising twists.
"The world has just got bigger and bigger and we are going to move into the world towards Dawn 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."
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."
