New pictures from the production set of “Game of Thrones” season 8 have leaked online. The cast and crew are currently filming a big action sequence with huge green screens surrounding the set. Siege weapons like trebuchets are being used, but perhaps in a different way. The following article contains spoiler.

Filming continues at the Magheramorne set in Northern Ireland. Trebuchets previously tested near the Titanic studios, where the massive King’s Landing set was constructed, have been transferred to Magheramorne, where it is currently being put to good use, Watchers on the Wall reports.

The cast and crew are busy with night shoots. The trebuchet has a lit projectile, which means fire will be used in an action scene. It doesn’t actually fire the projectile, with the report suggesting they may use digital trebuchets to do the actual firing and heavy lifting.

The pictures and the video have been taken from afar, so it isn’t clear which of the cast members are actually using the trebuchets. It's also not yet clear if this is, in fact, a siege. The report notes that the trebuchet can be used in battle to break enemy formations. They need not necessarily be used to bring down castle walls.

One good use for the fire-lit projectiles would be to ward off the Army of the Dead. Viewers already know that fire is a good weapon against the wights. Other ideal methods are dragonglass and Valyrian steel.

It will be interesting to see what weapons and strategies will be used against the Night King in “Game of Thrones” season 8. The show is expected to air sometime in 2019.
