Jackson: You know the black arrow's interesting cause it's gonna, y'know every time I thought about an arrow killing this bloody huge dragon, especially since Smaug became huge (which we'll talk about), but that means that since the dragon's big, that the arrow had to get big too. It just wasn't gonna work with a puny little normal arrow so the whole notion of the black arrow became almost more of a black lance, and then you needed a special bow to shoot it, which is the wind lance, a great name, I think you guys (indicating Boyens & WETA) came up with the name "the wind lance", which they've got mounted on these towers, like a sort of anti-aircraft system, like flak guns, flak towers all around.
Boyens: You still need to be a bowman though to be able to shoot it though.
