In fact the company might gone Mission Impossible on the leaks, according to an interview that Game of Thrones actor Nikolaj Coster-Waldau did with Elite Daily. According to Coster-Waldau, “They’re very very strict. It’s reached a crazy level this year. We actually get the scripts, and then when we’ve shot the scene — and we only have it digitally — and then when you’ve done the scene, it just vanishes. It’s like Mission: Impossible. ‘This will self-destruct.’”
With season 8 being the last season in the franchise, it is not surprising that HBO has gone to great lengths to try and keep it as much of a surprise as possible. Previously it had been reported that the show’s creators had filmed multiple endings to the series so that even the cast has no idea which will be the last scene that will make the cut.
Game of Thrones season 8 is currently set for a release in 2019 and while it might contain less episodes than previous seasons, it could potentially be a lot more epic where we heard that a battle scene in one of the episodes took 55 days to shoot.
