They were among the cast members who walked the red carpet for the final time in Belfast, where much of the drama has been filmed since it started in 2011.
It is a series that has made them household names, with many saying that returning to Northern Ireland to attend the exclusive screening felt like “coming home”.
With makers HBO notoriously guarded, the actors unsurprisingly would not be drawn into revealing spoilers.
However, all promised the most shocking season yet.
Harington, who plays Jon Snow (AKA Aegon Targaryen, to you and me, although he doesn’t know it yet), told Sky News he felt “overwhelmed” when he read the final scripts.
“I felt most upset – well, upset is the wrong word, but just overwhelmed. Overwhelmed that we’re here and that we’ve finished it.
“There was a point around season four or five where you’re like ‘this thing is never-ending. This is just going to go and go’.
“Now we’re done and I’m going to go back and watch the whole thing once and put it to bed.”
Series seven ended with The Wall coming down and our heroes (and villains) preparing for the final battle for Westeros, knowing they will have to defeat the deadly White Walkers and their Night King – plus their newly-acquired zombie ice-fire dragon.
It has been almost two years since those episodes aired, with fans waiting in anticipation to see how the Game Of Thrones ends – and who, if anyone, will end up on the Iron Throne.
Summing the final series up in three (well, four) words, Turner, who plays Sansa Stark, described it as “unpredictable, terrifying and visually stunning”.
She told Sky News: “It never really feels like goodbye. I don’t think I can convince myself that it’s time to say goodbye.”
Hampsted Wright said he didn’t believe the season could be bettered, saying: “It took nine months to film six episodes, usually it takes six months to film 10 episodes so that just gives you the scale of it.”
The hit show is known for its violent scenes, with 56% of its 330 characters dying across the series so far. Episodes in the final instalment have cost a rumoured £11.5m each.
Other stars who attended the screening included Richard Dormer, who plays Beric Dondarrion, Jerome Flynn (Bronn), Carice van Houten (Melisandre) and Pilou Asbaek (Euron Greyjoy).
Asked whether his villainous character would be behaving badly in season eight, Asbaek said he would be “very disappointed with myself if he didn’t do something horrible this season”.
Dormer said the final series would bring “a lot of goosebumps, a lot of raised hair, a lot of shocks – and a lot of blood”.
Well, this is the Game Of Thrones, after all. We’d expect nothing less.
