Looking ahead to the penultimate Game of Thrones season 4 episode, director Neil Marshall promises spectacular sets and large crowds of extras.

Every Game of Thrones season so far has had a spectacular ninth episode, and in this interview with the  Irish Film and Television Network, director Neil Marshall previews what we can expect from season 4, episode 9.

Beware of mild spoilers.

Marshall has previously directed the award-winning season 2, episode 9 “Blackwater,” and reveals that in some ways, that episode was simpler to make than the season 4 episode.

“The Castle Black episode has three different battles going on at the same time in different places,” Marshall reveals, “so it’s a bit more complex from that point of view.”

Speaking about the battle scenes, Marshall teases that there will be beheadings, and further enthuses, “we got to blow some people up, set people on fire and do quite a few high falls. We pack quite a lot of stuff in there.”

With 200 extras and a large number of stuntmen, “this episode is loaded with stunts, effects gags and visual effects. It’s a very, very action-packed episode!”

There is speculation that the episode will be called “Castle Black,” but that has not yet been confirmed.

Cat Taylor has added a few more small teasers from behind the scenes of Game of Thrones on the Making Game of Thrones blog.

Specifically, she has posted a few out-of-context comments about season 4 from the production office:

“We’re going to be killing the stuntmen 3 times each at least, so we’ll need to look at beards and hair.”

“They do say an owl is twice as hard to do as the eagle, and you know what that was like.”

“There is no silent wind, only noise wind.”

“We can’t tube the silent wind across?”

“No.”

Game of Thrones season 4 premieres spring 2014.
