"Klaatu, barada nikto." I've always wondered where that phrase came from, and being, in the grand scheme of things, only semi-geeky, I had never seen "The Day the Earth Stood Still." I saw it tonight, on AMC, and I actually let out an "A-ha!" when he said it. Cool movie, elevated above others of its time and genre by good acting, a good score and some timeless social commentary. What "Klaatu, barada nikto" means, however, I leave to the truly geeky.
