Sean Bean has revealed that a Game of Thrones special, featuring past and present cast members, has been filmed.

The actor – who played Ned Stark on the show – let slip that American late-night host Conan O'Brien will host the one-off episode, which was filmed in Belfast earlier this year.

“It was the last episode, so we all got together,” he told The Hollywood Reporter.“They decided to get all the characters together for a bit for this big show in Belfast and he kind of hosted the evening.“

Game of Thrones will come to an end after the upcoming eighth season. HBO has not confirmed a release date yet, but fans think they have worked out when the final batch of episodes may begin airing.

Asked whether he keeps in contact with his fellow cast members, Bean said has “only seen them on a couple of occasions”.

“It's funny with work, you don't really keep in touch,” he said. ”You do so many types of jobs in that part of the world. It's just like whenever I see old friends or even old drama school friends, it's just the same, we pick up where we left off last time.”
