9. WHEN WILL THE GAME OF THRONES SPINOFF SERIES PREMIERE?



Assuming that the Game of Thrones' spinoff goes to series, it still won't premiere for a few years from now. Game of Thrones Season 8, the final season, won't air until 2019, which suggests that the absolute earliest we'd see a spinoff series would be 2020. Even then, that may be too soon knowing how involved and tedious it can be to film a series on the scale of Game of Thrones. And while the budget for the spinoff series won't be as much as Game of Thrones' recent seasons, it's expected to still be pretty big. A safer bet may be to put the premiere of the Game of Thrones spinoff in early 2021.

8. HOW MANY EPISODES WILL THE GAME OF THRONES SPINOFF HAVE?



The early seasons of Game of Thrones had ten episodes and it's likely that a spinoff series will follow a similar pattern. Most HBO series have shorter seasons than broadcast television, so it'd be safe to assume this spinoff series wouldn't have seasons that are longer than ten episodes. Also, given that this spinoff isn't adapting a novel or book series, there's no guarantee the story that Goldman and Martin are cooking up will take more than a single season to tell. That seems unlikely given the subject matter, but at this point, there's no ruling out a limited series for Goldman's spinoff, possibly followed by more limited series based on other pitches.

7. ARE ANY GAME OF THRONES CAST MEMBERS RETURNING?



With the spinoff series set thousands of years prior to the events covered in Game of Thrones, it's hard to imagine that any of the actors featured in Game of Thrones would or even could return. Then again, never say never. It's expected that characters like the Children of the Forest and the White Walkers will appear, which means the actors who portrayed them on Game of Thrones have the best chance at returning. Otherwise, the only feasible way for actors from Game of Thrones to appear would be through some vision of the future (a real possibility seeing as magic is more prevalent during this early age of Westeros). Still, were the spinoff to glimpse into the future and see the time period of Game of Thrones, it'd likely be as a cameo appearance at best (possibly even reusing old footage).

6. WHO ARE THE NEW WESTEROS CAST MEMBERS?



No roles have been cast for the Game of Thrones spinoff at this time, but we can speculate about which characters will need to be cast. The only family named in the official synopsis is the Starks, and given the setting, it's a safe bet that Bran the Builder (the found of House Stark) will play some role. Others who were prominent during this Age of Heroes are Durran Godsgrief the Storm King, the Grey King of the Iron Islands, and Lann the Clever (from whom House Lannister claims their heritage). The synopsis also mentions "mysteries of the East", which suggests there may be characters who hail from lands that have yet to appear on Game of Thrones, like Asshai or Yi Ti.

5. WHEN WILL THERE BE A GAME OF THRONES SPINOFF TRAILER?



At this early stage, it'll likely be at least a year if not more before we see any kind of trailer for the Game of Thrones spinoff. Even then, it's possible that the first trailer won't actually include filmed footage, but be a tease of what's to come using previously seen footage or graphics that will give audiences an impression of what the series will be about. A trailer that's more a proof of concept rather than actual footage could be attached to the Game of Thrones series finale, using the opportunity to advertise the spinoff to what will surely be an enormous viewing audience.
