Production has been under way on Game of Thrones Season 7 since early September, and with the show's premiere pushed from the spring of 2017 to the summer of 2017, filming may still be ongoing for quite some time. The show has already shot in two major locations, in Belfast, Northern Ireland, and in Seville, Spain. But now the show has shifted to another location, the coastal city of Dubrovknik, Croatia. Today, we have the first video and photos of three stars arriving on the set, Hafthor Júlíus Björnsson (The Mountain), Lena Headey (Cersei Lannister) and Nikolaj Coster-Waldau (Jamie Lannister).

The Dubrovnik Times debuted this video and photos, revealing that some thought the production wouldn't return to this Croatian city, which had been used in previous seasons for scenes in King's Landing. The photos and videos don't show any of the actors in costume, and it seems they are simply arriving on set, with the video showing that all of these stars are shielding themselves from the paparazzi cameras with umbrellas, despite the lack of rain in Croatia.

This report also reveals that filming began today on Dubrovnik's famed city walls, with rumors surfacing that this shoot will last for three days. These photos come just days after UFC president Dana White confirmed that MMA fighter Conor McGregor has been cast in one of the final two seasons of Game of Thrones, but it hasn't been confirmed which season he'll be appearing in. No details about the character he'll play have surfaced yet, but many have hoped that he will be squaring off against The Mountain, after a video surfaced last year of both Conor McGregor and Hafþór Júlíus Björnsson sparring together. This report doesn't indicate what will transpire during these scenes in King's Landing quite yet.

Game of Thrones Season 6 ended with Cersei Lannister having vanquished their enemies in King's Landing, in a most brutal fashion. Refusing to show up for her own trial, she used Qyburn (Anton Lesser) and some conniving youngsters to lure her cousin, Lancel Lannister (Eugene Simon) below the Great Sept of Baelor, where she used some properly placed candles to ignite the barrels of wildfire hidden in the tunnels beneath the Great Sept, killing the High Sparrow (Jonathan Pryce), Loras Tyrell (Finn Jones) and Queen Margaery Tyrell (Natalie Dormer). Devastated by his Queen's death, King Tommen (Dean-Charles Chapman) took his own life, leaving the throne to Cersei Lannister.

Cersei was crowned the new Queen just as Jamie Lannister returned to King's Landing. The end of Season 6 also showed Daenerys Targaryen (Emilia Clarke), with her massive fleet, and three dragons in tow, setting sail for Westeros, to stake her claim to the Iron Throne. Since Game of Thrones has completely surpassed the George R.R. Martin books at this point, fans are now in uncharted territory, as the long wait until Game of Thrones Season 7 continues. Take a look at the latest video and photos from the set, as Game of Thrones continues production.
