though i hate to stray off topic, was the Mouth blind? in that picture that ninja91 put out(and many other places i have seen) his helmet stretches over his eyes. i seem to recall tolkien saying something about the mouth looking about after Aragorn and the others werent fooled by frodo's mail. was this possible lack of sight just Jackson's idea, or did tolkien really write something about this... just how lofty was his helm?
