Speaking of acrobatics, and knowing that no electrons were harmed during the filming of any of these movies, but why is it that since Helm's Deep elves feel the need to leave their bows slung? Wouldn't it have been nice when, at the same time the elves leap over the dwarven wall that a million arrows accompany them? They were more than ready to shoot arrows at Thorin, who posed much less of a target, and probably was wearing mithril undergarments.
