Filming in Iceland began yesterday and will run until August 1 according to Morgunblaðið (The Morning Paper).
In addition to the previous location of Þingvellir listed here, there is now confirmation coming from Morgunblaðið that Game of Thrones will also be filming in Þjórsárdalur and Hengill.
Morgunblaðið spotted Game of Thrones filming in Nesjavellir yesterday as well.
"It appears that shooting of the popular tv series, game of thrones, has started close to Nesjavellir today and according to our sources the cast and crew were spotted in Dyrfjöll above Nesjavellir in the sun today."
Also of interest, and a bit of a surprise to me, is that Gwendoline Christie (Brienne) and Maisie Williams (Arya Stark) have been spootted in Iceland this week! Both were spotted by Morgunblaðið and by fans who shared photos.
Well we can assume that the Summer shoot in Iceland will be for Arya's and Brienne's arcs, at least in part.
- The mountains and shorelines could make for a nice Maidenpool or Crackclaw Point for Brienne, perhaps even Duskendale. Will we get Ser Hyle Hunt this year?
- I would guess that the Arya scenes will be her travels with/ without Sandor in the Vale of Arryn or maybe the Saltpans. An outside chance some of it could be used for Braavos as well perhaps...
