Some random comments: About iron from the stars, i think there was plenty here already before life began. If you mean when the planet was forming then yeah, it came from the sun.
I'm nowhere near sick of space movies because the good ones are far and few between. Moon, Star Trek, WALL•E, Sunshine... that's only 1 or 2 a year.
2001: ASO is different because when heavy shit happens, the people will barely acknowledge it then move on as quick as possible, and get back to the small talk about the fake chicken sandwich. It added to the grandeur Kubrick was going for. The Fountain explores the hell out of feelings. But yeah, they're both trippy.
Does anybody know why they didn't let Aronofsky do a commentary? Even Mad Men gets 2 (lousy ones) per episode.
Another good one guys, lots of great info about the movie. Now, please explain Mulholland Drive to me. And how do magnets work?
