As the ‘Game of Thrones’ season 7 filming continues, several actors have come up in Belfast which brings on even more speculations about the upcoming installment.

Fans have taken to social media to share their photos in which Lena Headey, Indira Varma and Rosabell Laurenti Sellers appear.

Other cast members who have turned up in the Northern Ireland capital include Gemma Whelan and Alfie Allen while a fan also came across actor Pilou Asbæk.

According to fan site Watchers on the Wall, the recent ‘Game of Thrones’ filming was focused on a scene between siblings Yara and Theon Greyjoy while in battle at sea. Their uncle Euron catches up and will reportedly catch one of them.

Moreover, one ‘Game of Thrones’ theory suggested that Euron will team up with Queen Cersei and could bring down one of the Sand Snakes.

Such speculation has been popular due to the likelihood that Euron’s last choice for an alliance would be Headey’s character, as Daenerys has left Meereen and is not likely to take interest in a marriage proposal with ship-building benefits.

Peter Dinklage was recently spotted at Belfast Airport, as shared by one of the fans on Geek Syndicate’s Twitter account.

At a separate time, Kit Harington was spotted at the same airport and posed for a photo with two fans.

The production of the award-winning series has been pushed back this year. As winter has arrived in the continent of Westeros, the producers at HBO sought for the ‘Game of Thrones’ season 7 scenes to be filmed under the appropriate weather conditions.

“Now that winter has arrived on ‘Game of Thrones,’ executive producers David Benioff and D.B. Weiss felt that the storylines of the next season would be better served by starting production a little later than usual, when the weather is changing,” HBO programming president Casey Bloys stated.

Comprised of seven episodes, filming will be carried out in Northern Ireland, Spain and Iceland to be directed by helmers who previously worked on ‘Game of Thrones.’ These include Alan Taylor, Jeremy Podeswa and Mark Mylod. Newcomer Matt Shakman has also joined the series to direct one or more episodes.

There will also be a new filming location as announced by HBO, as reported by Watchers On The Wall. Several ‘Game of Thrones’ season 7 scenes are set to be filmed at Las Atarazanas, the Royal Dockyards of Seville in Spain. Such place is known as an old-fashioned shipyard with Gothic design. According to the report, this location may not be used as a shipyard by the production team but may depict another Westeros place, such as Oldtown.

While there has been no official date, the ‘Game of Thrones’ season 7 premiere will be pushed back to summer of 2017.
