1. BATTLE OF THE BLACKWATER (SEASON 2)
I had forgotten how many stages there were to this battle. Honestly, the wildfire bit was the main thing burned into my memory. George R.R.

2. BATTLE OF CASTLE BLACK (SEASON 4)
It involves a 400-by-30-foot green screen. Yikes.
3. MASSACRE AT HARDHOME (SEASON 5)
4. BATTLE FOR WINTERFELL (SEASON 6)
