Game Of Thrones Season Eight Might Air In 2019

In interviews to promote his new film Shot Caller, Nikolaj Coster-Waldau has revealed that the next season of Game Of Thrones doesn’t start filming until October, and that it could be two years until it airs.
He told Collider: “You get the scripts a month before we start shooting, or six weeks, and then you know what’s going to happen that season. But, I don’t know what’s going to happen next season. We go back in October, so maybe in the next few weeks, we’ll get the scripts and I’ll find out. I’m very curious.”
Based on the production schedule for season seven, Collider estimates that filming will last until April 2018, then once post-production is factored in it could be ready to air in September 2018.
However, in an interview with BT, Coster-Waldau said that it could be a much longer wait: “We still have a year left working on Game of Thrones and the last season will probably not be broadcast for two years.”
