This video has surfaced recently, so far only in low def, but it will do. We get to see the staging and the training for a number of fights (duels and otherwise) and full blown battle scenes from S4. How glad are we that Neil Marshall is back? Very! The directors, actors, and first and foremost the Sword Masters CC Smiff and Tommy Dunne, and Senior Armourer Natalia Lee, sound off on all the different aspects of the stunts involved.
Once more, beware of spoilers. You could learn about action-related plot points from the new footage and commentaries.
Hear Me Roar: Many bits are actually quite interesting for us readers as well, as they reveal how they plan to adapt the story. I love the catapult bit at the end, by the way.
