A Game of Thrones actor has hinted at the intense security measures HBO has put in place to protect season eight's scripts.
Liam Cunningham, who plays Ser Davos Seaworth, says the security measures are so complex that he has trouble accessing his lines.
"I got all [six] scripts," he told IGN. "[But] I can't open them because of all of the security and I can't work it out. I can't open them. It's like pulling a pin out of a grenade."
The heightened security is unsurprising given the show's seventh season was beset by a series of leaks.
But the interview has sent Game of Thrones fans into a frenzy, with many of the view that Cunningham was suggesting HBO keeps digital scripts in a secure location that are only able to be viewed on approved devices. (Imagine, for a moment, Kit Harington being ushered into a sealed room somewhere in Belfast to view the scripts on an iPad that's definitely not connected to wi-fi.)
The majority of secretive film and TV projects use paper scripts to prevent hackers from obtaining digital copies. As an additional security measure, the paper is lined with a filament preventing them from being photocopied.
Paper scripts may also come with large watermarks or hidden details so that if copies find their way online, the source of the leak is able to be identified.
In addition, big-name films and TV shows usually only distribute partial scripts. This ensures actors are able to learn their character's scenes and, if the papers find their way into the wrong hands, the entire storyline isn't given away.
For example, the Twin Peaks script was about 800 pages long but only one actor, reportedly, (Kyle MacLachlan) was given access to the entire script.
While HBO hasn't revealed the exact security measures around the Game of Thrones season eight scripts, it's clear the TV giant is guarding the ending very, very closely - even from its own cast.
