Filming is about to get underway on Season 8, with October long touted as the expected starting month. We've got some more concrete information on this front recently, with a number of actors arriving in Belfast recently - and a table read taking place too.
The likes of Kit Harington, Emilia Clarke, Nikolaj Coster-Waldau and most others have been spotted in the last couple of weeks too, including one actor whose return could be considered a spoiler.
As for its ending, The Hollywood Reporter notes that it could run until August 2018, which makes it one hell of a long shoot. For comparison, Season 7 started filming at the beginning of September, and finished early in February, so filming Season 8 could take twice as long. Iain Glen offered some clarification on why this is, as he said that since everyone is together, it means they only have one filming unit rather than the usual two (via Watchers on the Wall).
That means we're almost certainly not going to see it until 2019, which HBO's programming president Casey Bloys had previously suggested. Season 7 aired five months after filming wrapped, and with Season 8 even bigger in scale it could take longer - a return to its old April slot, or another summer outing (given the ratings success) could be likely for 2019.
