Speaking of that line that Aragorn's mother says in the book there were somethings about that scene that I thought funny.
First was when Elrond says, "You need more men." and Aragorn replies, "There are none." I really expected Elrond to say, "What happened to the elf army I gave you? Oh yes, yes, I remember... they are all dead!
Another part in this scene that is rather funny is when Elrond says, "You have the power to raise an army more deadly than any that walks this earth." Look at Elrond and you will notice him shake and his eyes bug out like he had too much coffee.

Don't get me wrong for I love Hugo Weaving for he is one of my favorite LOTR actors, but that scene was weird for some reason.
