VIDEO : 'Game of Thrones' Utilized Killed Drones To Avoid Spoilers

With Game of Thrones' upcoming eighth season being its last the risk of spoilers is higher than ever.

That means the HBO series went to some seriously high-tech lengths to keep things secret.

According to comicbook.com, actress Sophie Turner told fans about a 'drone killing' device.

If a drone flies above sets, there's a thing that can kill the drones which is really cool. It creates a field around it and the drones just drop. It's very X-Men.
