Fans should brace themselves for a ton of fresh faces in Season 7 of “Game of Thrones.” A number of new characters are slated to appear in the upcoming installment of the HBO series, but there’s one in particular that fans are looking forward to.

British actor Jim Broadbent — who played Horace Slughorn in “Harry Potter” — has officially been added to the “Game of Thrones” cast. He will appear in Season 7 in a “significant” role, according to Entertainment Weekly. There are, however, no further details regarding his participation on the show. “Game of Thrones” is slated to begin filming in Northern Ireland, Spain and Iceland in the near future, though the new episodes it won’t premiere for nearly a year.

Rumors have also swirled that the show may be bringing on old characters fans believed they’d seen the last of. On Aug. 25, Jason Momoa sparked rumors of a Khal Drogo revival when he was seen posing alongside “Game of Thrones” writers David Benioff and D.B. Weiss in an Instagram photo.

As it turns out, the trio was simply reunited in celebration of Guinness giving Momoa his own special beer. He and his family were in Ireland visiting and the “Game of Thrones” showrunners tagged along to enjoy a Momoa inspired brew. Fans further speculated that he may be brought back to life on the show following his tragic death in Season 1 after he shared a picture of a piece of fan art on his personal Instagram page. Momoa wrote that he was thankful Daenerys (Emilia Clarke) burned his body to there was no chance he could return as a white walker, which appeared to be what the fan was depicting in the picture. TMZ has assured fans there will be no more Drogo — dead or alive.

While it remains unclear who is or isn’t joining the “Game of Thrones” cast for it’s final two seasons, eight new roles have been added. The parts were outlined in a document obtained by “Watchers on the Wall,” revealing the show is adding a priest, a warrior, a gate guard, a city guard, a merchant, a lovely lady, a young lord and a lieutenant. Descriptions for each part can be found HERE. Many of the roles appear to be smaller, supporting roles, but some will be more lasting. Some have speculated that the Lieutenant may be joining Daenerys in her quest toward Westeros. Much of that stems from the actor description, which calls for a man in his 20s who is “athletic, physically fit and disciplined warrior” — in other words, precisely what Daenerys looks for in a man.

“Game of Thrones” will return to HBO for a seven-episode season in 2017.
