There’s a big war coming to Westeros in “Game of Thrones” season 8, with production sets now being prepared for the battle. Leaked pictures reveal how set construction is a little different this time around. The following article contains minor spoilers.

Construction of the Winterfell set had been ongoing for a long time at Moneyglass, Northern Ireland. The production crew has built crenellations and towers this time rather than using CGI like they did before. This means that the castle will see some action in the TV series.

Leaked pictures from the Moneyglass set posted on Winter is Coming shows that filming has already begun. Only the exterior can be seen in the picture, so it isn’t clear which members of the cast were involved in filming.

The exterior is covered in fake snow. The report notes that even though natural lighting is low on the day of filming, due to the overcast sky, there is sufficient artificial lighting on set to make sure the scenes are good and bright on screen.

It isn’t clear if they are currently filming actions sequences, especially of the Winterfell castle coming under attack. The report notes that it is possible that cast members are currently filming scenes showing their respective characters fighting off the White Walkers.

Meanwhile, more pictures of the set being built at Titanic Studios in Belfast have leaked online, too. The images posted on Winter is Coming show a dummy placed on top of one of the walls. The set depicts King’s Landing, and the report notes that the dummy may be standing in for a soldier, who will die when the city is attacked, presumably by fire.
