Game Of Thrones: 25 Key Details You Need To Know & Remember For Season 8

3. The Battle Of Winterfell

The centrepiece of Game of Thrones' eighth season is the biggest battle the show has ever done. Actually, scratch that. It's the biggest battle any TV show or movie has ever done.

Directed by Miguel Sapochnik, the Battle of Winterfell - which, as you'd expect, is the living vs the dead - will take place in the third episode of the season (which, as mentioned, is the longest). It's been compared to Helm's Deep, but also far eclipses its runtime. Sapochnik and the cast and crew shot outdoors for 55-nights straight in the Belfast cold, before things then continued for a few more weeks indoors. It's a battle on a scale we've not seen before, and that's really saying something for this show.

Sapochnik has ensured that it's not just action for the sake of it though, instead making sure everything is rooted in character and story, which has been such a huge credit to his other battle sequences. As he explained: 'It feels like the only way to really approach it properly is take every sequence and ask yourself: 'Why would I care to keep watching?' One thing I found is the less action - the less fighting - you can have in a sequence, the better."

Needless to say, though, there is still going to be a LOT of action and fighting in this episode as the dead come to Winterfell, and quite likely we'll lose a number of familiar faces at this point.
