Game of Thrones has always been a fairly secretive show, with reports of the scripts being automatically deleted and extras sworn to secrecy.
And as the final episodes draw ever closer, the techniques used to keep the scenes secret have been escalated.
In order to keep the scripts and events safe, even the actors themselves were roped in to protecting the truth.
Sansa Stark actor Sophie Turner recently spoke out at New York Comic Con about her experience keeping the final season under wraps.
Speaking to Vulture, Sophie explained: “The secrecy is crazy. We have a whole different name for it when we’re shooting it.
“I think this season it was like The Tree of Life or something.”
If this wasn’t enough, fans who figured out the truth behind The Tree of Life began looking for opportune moments to spy on the show’s filming.
Some instances of this included flying over the sets with a drone – but Game of Thrones producers had a plan for this as well.
She revealed the sets had a “drone killer” which stops the machines in their tracks.
Sophie said: “I don’t know how it does it. It creates like this field around and the drones just drop.”
Perhaps the most interesting piece of subterfuge was that the cast were dressed up and trounced around false sets. Sophie continued: “Also, we shoot fake scenes.
“We got into costume in Croatia because we know the paparazzi lurk around there, so we would spend like half a day doing nothing.”
Meanwhile Sophie’s on-screen sister, Arya Stark actor, Maisie Williams recently revealed her secret fantasy about the show’s ending.
Speaking about secrets in the fantasy epic, Maisie told The One Show: “The show has grown, as we have, into this industry.
“We’ve got better at it, as it’s become more important to keep secrets.”
However she went on to add: “But also, I know what it’s like for someone to spoil my favourite TV show!”
She went on to joke that spoiling the end of the show for fans is her “ultimate fantasy.”
She explained: “I would love to just turn around to a fanatical fan one day and ruin the ending of the show.
“Watch their face, like, [drop]. That would be fun!”
Game of Thrones season 8 will return to HBO and Sky Atlantic in 2019. Seasons 1-7 are currently streaming on NOW TV.
