Game of Thrones, having wrapped up a wildly successful sixth season, starts production this month on its next season, which will run for seven episodes and won’t debut on HBO until the summer of 2017, the network announced recently. The season will mostly film in Northern Ireland, while also filming in Iceland and various locales in Spain (Sevilla, Caceres, Almodovar del Rio, Santiponce, Zumaia and Bermeo.)
The next season of Game of Thrones will almost certainly focus on Daenerys Targaryen’s long-awaited attempt at a conquest of Westeros, as well as Jon Snow’s early days as King in the North, the encroaching threat of the White Walkers and Cersei Lannister’s reign on the Iron Throne (following the brutal murders of most of her enemies at the end of Season 6). Now, we have some clues as to who might be joining them in Westeros in the seventh season.
The Game of Thrones site Watchers on the Wall has obtained a casting call for the seventh season, including casting notices for several new characters:
It’s worth noting that most of these characters are going to be on hand for short shoots of a week or two, and are therefore probably only in one or two episodes of Game of Thrones season 7. The exceptions are "Lieutenant," "Cate Guard" and "Warrior."
The release of casting notices is another perennial landmark on the Game of Thrones calendar. Usually, the reactions to such listings among Thrones fans are to wonder who these characters are, how they fit in with the books and any not-previously-cast book characters, and even to speculate on what actors might fit the parts. While we’re well past the books at this point, there’s still a chance that some books-only characters could still show up.
Game of Thrones' seventh season will debut in the summer of 2017 on HBO; an official date has not yet been announced.
