Today was a huge day for Game of Thrones filming, according to our sources. Portions of a major scene were filmed in Ballintoy, Northern Ireland, and reports say that one of the sixth season’s new stars was front and center.

Sources report that Danish actor Pilou Asbæk will be playing the role of Euron Greyjoy. The actor was spotted shooting today with the cast around Ballintoy Harbour, in a scene that involved a crowd cheering for Euron.

Asbæk starred in the successful Danish series Borgen as Kasper Juul, along with GoT guest star Birgitte Hjort Sørensen. He appeared as Paolo Orsini on The Borgias, and is playing Pontius Pilate in the newest version of Ben-Hur.

UPDATE: It’s official! HBO has confirmed that Pilou Asbæk has been cast in season 6 of Game of Thrones as Euron Greyjoy.

As for the scene being filmed, spoilers below!

Sources say that the Kingsmoot was at least partially filmed today. The scene was very visible from the cliff paths nearby. Yara was present for the scene, as expected. There was no Victarion, as we’ve also been predicting for some time.

Our source did see someone who appeared to be Aeron, playing the Drowned Priest’s role in leading the Kingsmoot and speaking often. They didn’t think it was the same actor from season 2 who appeared as a Drowned Priest, or anyone they recognized but it was difficult to tell for certain in this case.

The filming at Ballintoy Harbour will continue for the rest of the week, so hopefully there will be more sightings, confirmations and details to come!
