Filming of “Game of Thrones” season 8 has finally begun. Although there was no official announcement about it, cast members have been spotted in Belfast, the main base of the production. Sets for the show have already been constructed, and the presence of the actors now confirms that the cameras have started rolling.

Liam Cunningham (Davos Seaworth) and Nathalie Emmanuel (Missandei) were spotted by a fan in Belfast. The two were watching a boxing match together, Watchers on the Wall reports.

Jacob Anderson (Grey Worm) and Gwendoline Christie (Brienne) were reportedly spotted on a flight to Belfast by another fan. However, there were no picture or other visual evidence to confirm this sighting. The other cast members reportedly seen at the airport were Kit Harington (Jon Snow) and Rupert Vansittart (Lord Royce).

The return of Lord Royce is important in the HBO show as he may be the one to command the forces from the Vale. Every soldier will count in this final war against the Night’s King.

The other set of actors spotted on the streets of Belfast were Joe Dempsie (Gendry) and Hannah Murray (Gilly), along with a few aforementioned actors, Watchers on the Wall reports. All actors were seen in the city, not on set of the TV series. Security may be particularly tight this year since this is the last time they will all be filming. However, pictures of the sets have already leaked online, so more can be expected in the coming days.

The presence of these actors seem to suggest that scenes related to the North are being filmed at the moment. There should eventually be a Jon Snow-Samwell (John Bradley) reunion, and Jaime Lannister (Nikolaj Coster-Waldau) may join the fight later on.

Although most of the storylines have converged in “Game of Thrones” season 8, there may still be a need for the second production unit. Lena Headey (Cersei Lannister) and the others still need to film scenes at locations depicting King’s Landing.
