HBO is pulling out all of the stops to make sure absolutely nothing gets out about Game of Thrones' final season that they don't want to get out.

It's still a year until Game of Thrones season 8 airs and producers are doing everything they can to make sure the final season of the hit TV show is not leaked to death before it's even had the chance to hit screens. 

Nikolaj Coster-Waldau, who stars as Jaime Lannister, disclosed the extreme lengths the producers of the show are going to in an interview with Elite Daily.  

He told the publication that they are so concerned about leaks that the cast have been given scripts in digital format only and that these scripts then 'self-destruct' after the scene has been shot. 

"They're very, very strict. It's reached a crazy level this year," he said of the producers in his interview with Elite Daily.

"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'."

HBO may be keeping a tight lid on the final season but that doesn't mean they haven't shared anything, it just means they want to control what's coming out about the show. 

Previously, HBO actually hinted that quite a few characters will not survive the final season alive. 

According to Variety, Francesca Orsi, HBO SVP of drama teased the deaths during an appearance at the INTV Conference in Israel alongside programming president Casey Bloys.

The spoiler was dropped as she shared her reflection on being there when the read-through of the series finale took place.

"It was a really powerful moment in our lives and our career," she said: "None of the cast had received the scripts prior, and one by one they started to fall down to their deaths."

A separate report in The Express suggests that one of those to meet their death might include Daenerys, played by Emilia Clarke.

That speculation comes after a fan Twitter account, Irish Thrones, shared images of a rig-like structure at the Titanic Studios in Belfast that may have been a dragon and other images showing fire damage.  

That speculation has been further fuelled by Emilia Clarke being missing from the GOT cast members who turned up to film a major scene at the King's Landing set in Seville.  

Clarke herself hasn't given much away except to say in an interview with Variety that fans should brace themselves for some "weird s**t."

"You'll know what I mean when you see it," she said. 

Game of Thrones' eighth and final season is set air on HBO and Sky Atlantic in 2019.
