The bloody set-piece at the heart of the most expensive episode of Game of Thrones ever was made in Australia.
The day after the season-six finale aired, and a little more than a week after the landmark Battle of the Bastards episode screened, Melbourne post-production house Iloura was finally allowed to share with the world its pride in having pulled the strings in the 22-minute battle sequence that saw a giant, hundreds of horses and thousands of soldiers fight it out to the bloody end as Jon Snow (Kit Harrington) and his sister Sansa Stark (Sophie Tucker) attempted to reclaim their family seat of Winterfell. 
"Battle of the Bastards is shocking in its audacity," the show's visual effects producer Steve Kullback said. "More shocking still that we pulled it off, and so much credit for that goes to Iloura.
"We are up close and personal in this battle with CG [computer graphics] horses and collisions right in front of the lens, and we constantly needed to review Iloura's shots side by side with the photography because it was hard to remember, and even harder to see, the difference between what was shot and what was added. Amazing."
Iloura boss Simon Rosenthal admits this wasn't just the first Game of Thrones episode he had worked on - it was the first he had watched: "I'd never seen it before we got the job, though my wife is a huge fan."
Iloura was invited to pitch for the job because it had built CG horses before - for Seth MacFarlane's A Million Ways to Die in the West (2014) and Charlotte's Web (2006).
But despite having those equine runs on the board, they still had to prove they were up to the task of creating dozens of believable, battle-ready horses, as well as replicating the real-world soldiers in order to create hordes.
Testing and development took two or three months. The build itself, led by supervising effects producer Glenn Melenhorst in the firm's South Melbourne studio, began in   October 2015.
The last "assets", as the computer-generated images are called, were delivered in   June, just weeks before the episode aired.
The horses were created from the inside out. "We had to build muscles for them, a whole articulated skeletal structure," Rosenthal said. "The trick is to get photo-real animals behaving in a real-world way. It's a two-part challenge: Part A is to get the asset looking right, and part B is to get it behaving right through the animation."
Anyone who saw the remarkable battle sequence will likely agree that they succeeded on both fronts.
But such work doesn't come cheap.
Rosenthal won't say what the budget for the episode was, but he concedes it was "fairly extravagant - but the fan base has an incredibly high expectation of this show that demands to be met".
