HBOGame Of Thrones producer David Benioff has hinted that the show will be controversial.
According to Access Hollywood, Benioff explained that HBO has allowed the series to include scenes of sex and violence.
"One of the things that had to be done with [my previous project] Troy is so many things had to be cut because we were trying to do a two-and-a-half hour movie and tell this massive, massive story," he said.
"Here, because we have ten hours to tell the story, we're able to include all the major characters... and we're able to do it the way [author] George [R. R. Martin] does it in the books in terms of the darkness of it and the violence of it and the sexuality of it, which a major studio would never let you do, even if you're lucky enough to get an R rating. This is beyond R."
Benioff, who explained that the show is about "power", added: "A lot of people get killed. George's world is a violent world - there's a lot of killing and bloodshed and eviscerations and decapitations and there's a lot of sex. It's one of the things that I loved about these books." Game Of Thrones will premiere on HBO on April 17
. The show will air on Sky Atlantic in the UK.
