The wait for Season 7 of "Game of Thrones" is definitely going to be a long one with the creators confirming that the show will premiere much later than it did in the previous seasons. However, this has made the fans more determined to find out what they can expect in the upcoming season.

On July 6, the showrunners David Benioff and D.B. Weiss had revealed that the production itself will start later than ever before. "We're starting a bit later because at the end of this season, 'winter is here' — and that means that sunny weather doesn't really serve our purposes anymore. So we kind of pushed everything down the line, so we could get some grim, gray weather, even in the sunnier places that we shoot."

The perfectionists that they are, fans did not expect anything less from Benioff and Weiss, who have gone ahead of George RR Martin's books. "Game of Thrones" will only feature one more season, which would hopefully reveal which rightful heir sits on the Iron Throne.

As the successful series draws to an end, the actors have also started receiving bigger paychecks. Reportedly, Peter Dinklage (Tyrion Lannister), Kit Harington (Jon Snow), Lena Headey (Cersei Lannister), Emilia Clarke (Daenerys Targaryen) and Nikolaj Coster-Waldau (Jaime Lannister) will all receive at least $500,000 each per episode and it is only expected to increase in Season 8.

Meanwhile, the upcoming season is expected to feature only seven episodes, a major bump from the annual ten-episode format. However, the show is predicted to make up for it with longer episodes, following the trend set by the Season 6 finale, which ran for 69 minutes.

The season will also feature new and amazing characters and from the following leaked casting calls, they are all going to make significant difference in the story by having an impact on at least one of major characters. The casting calls were shared by "Game of Thrones" official fan website. Watchers on the Wall:
