ONE MORE MATRIX COMMENT: The Philip K. Dick influence is all in the "question reality" themes and nowhere else. If Dick was writing the Matrix, Neo would've still gotten out and possibly saved the world, but been unhappily married and in love/lust with a coworker. And his wife--someone who lived their life in the Matrix and wasn't ever thinking about getting out--would've had a much larger role. Dick did some weird stuff, but it all happened to real people. In the Matrix, we're not even sure who the real people are at this point.
