“Always expect the unexpected,” Ian Glen (Jorah Mormont) teased about “Game of Thrones” season 8 in a recent interview. Meanwhile, new pictures from the production set at Northern Ireland have leaked online, revealing a massive battle in the North.

The popular HBO TV series is known for unexpected twists and turns. Speaking with India Today, the actor teased that the upcoming final season will still have “loads of surprises.”

As far as Jorah's storyline is concerned, Glen said his character will now be seen as a “permanent fixture” in Daenerys Targaryen’s (Emilia Clarke) inner circle. The heroes will have to fight the biggest war of their lives as the Night King invades Westeros with the seemingly unstoppable Army of the Dead.

"The scale on which the final season has been mounted is amazing,” Glen said. The actor added that the final season will reflect how this is the “biggest TV show ever.” Filming has been ongoing for a long time, even though there are only six episodes to shoot. Glen said this is because they are filming some highly complicated sequences.

The long production schedule means that fans will have to wait until 2019 to watch the show. Glen said that the long gap will only add to the frenzy.

Meanwhile, new pictures from the production set in Moneyglass, Northern Ireland have leaked online. The pictures posted on Watchers on the Wall show the filming of a massive battle sequence in the North. The following portion of the article contains spoilers.

Winterfell will indeed see some massive action in “Game of Thrones” season 8. The leaked pictures show blood-stained walls, and props of Unsullied corpses lying on the ground near the walls of the castle set.
