I never thought cute little Elijah could look so creepy! That scene in Osgiliath, when he's looking upwards and the camera looks down at him so it looks like his eyes have rolled back, and he goes "They're heeere. They've come"... *shivers*
And that last speech by Sam should be incredibly corny, but Sean Astin puts so much sincerity into it that it's really not.
I love this film!
