Game of Thrones has released a behind-the-scenes video of the "Battle of the Bastards," and it's full of interesting facts.
1. That was an actual wall of cavalry charging at Kit Harington (Jon Snow), not CGI.
2. The horse master, Camilla Naprous, says this was the most responsibility she's ever had on set with 80 horses total.
3. Even the big clash used actual actors and horses charging past Jon Snow.
For that first big wave of cavalry, production shot about a dozen horses charging at each other and pulling up at the very last minute to make the clash look as real as possible. The rest was filled in with CGI and layering.
