What seems to be partially confirmed at this point is the intentional delay in the release date of “Game of Thrones” Season 7 primarily because the production team wanted to wait out the real winter in Ireland before they shoot the scenes featuring the battle between the humans and the white walkers in snow, considering that both the winds of winter and winter had already arrived.
There were also reports coming out lately saying that “Game of Thrones” Season 7 shall only have seven episodes.
During the San Diego ComicCon, executive producer David Benioff explained the decision to postpone the Season 7 premiere of “Game of Thrones” from spring to summer of next year because of production considerations.
He said that the arrival of the dreaded, multi-year winter long predicted for Westeros requires a shift in production, which is not taking place.
Benioff said that winter is upon the TV series and it so happens that they have been shooting in places where there are trees. He explained that they have to wait until the leaves fall off to shoot scenes as winter. With that being said, production of “Game of Thrones” Season 7 could actually finish in February next year.
