Filming for Game of Thrones Season 4 keeps on chugging along. Not surprisingly, the filming includes a massive battle the likes of which we’ve never seen on the show, apparently.

On the Making Game of Thrones blog, reports from the set in Belfast, Northern Ireland, that shooting is underway for a major battle that takes place in an episode directed by Neil Marshall . If that name sounds familiar, it’s because Neil also directed Season 2’s penultimate episode, “Blackwater,” which focused on Stannis's attempt to take over King's Landing. Apparently whenever GoT needs a battle shot, they call Neil. (We're not complaining.)

According to Making Game of Thrones, this battle does not take place on the water like the wildfire-laden battle of "Blackwater." The battle is also not as all-encompassing as “Blackwater,” since most of the cast and directors have already having completed their filming for Season 4. And based on previous spoilers, we know it will take place in Season 3, Episode 9, as that's the episode Neil Marshall is directing.

Cat Taylor gives us one more clue about the battle: “You’ve never seen an army like this on Game of Thrones.”

So what battle could we be talking about? We speculate below based on the A Song of Ice and Fire book series.

The battle takes place on land, involves only a few main characters, features an unusual army, and will, based on the pattern of the previous three seasons, be the climax of the season. Based on where the story is in A Song of Ice and Fire, the battle described sounds a lot to us like Mance Rayder’s attack on the Wall. Mance’s army features giants and wargs, which we've only glimpsed and haven't seen in action, the attack takes place on land, and the fight only features wildlings, the Night’s Watch, and Stannis’s army, while leaving out everyone in King’s Landing and Essos.

If this battle is anywhere close to as thrilling as the one in “Blackwater” then we’re all in for a treat, and with the same director at the helm, we like our chances.
