Game of Thrones' creators are known for going to extreme measures to deter spoilers. But as the final season of the groundbreaking series approaches, the cast is reportedly growing anxious about spoilers getting out, again.

Ben Crompton, who plays Night's Watch member Dolorous Edd, told Metro that there's a "slightly different atmosphere on set."

“Apart from being contractually obliged not to say anything, [the cast has] a real affection for the show," said Crompton. "We were filming the other week and there seemed to be something flying above. Everyone was suddenly going, ‘Is that a drone? Is that a drone?’ It turned out it was from the SFX department on the other side of the set trying something out. But there was just this moment there thinking, don’t let there be any spoilers or anything, just let it happen.”

Crompton also explained that while the cast knows everyone is more or less fair game to be killed, it's a bit different as they film the final episodes. “In previous seasons, whether you survived that series or not, you knew the show was continuing," Crompton explained. "Now whether you survive or not, it’s coming to an end. It’s something I’m very proud of. To be honest, there’s so much work to be done, you can’t really have time to sit down and get nostalgic yet.”

Game of Thrones' final season is set to premiere in 2019. But, as fans of the most-pirated series know, it'll certainly be worth the wait, especially as Kit Harington—who plays Jon Snow—says the final season will be "bigger than it's ever been."
