oooh, yes... just imagine the camera angle spinning around as he runs up the chain to the cave troll's head! Or super-slow-motion views of him drawing and firing his bow... !
Actually I think that kind of photography would have been a little overboard for LoTR.
Oohh, how about a scene where Legolas flips all the way around picks up a bow and some arrows on the way around and then starts firing them on the second time around. Like Neo did with the shotgun when they went to rescue Morpheus.
