I was actually nine or ten when I first watched the 04 version, having grown up with the VHS special editions (it was 04 or 05).
I remember wondering how they put Hayden Christensen in 1983. They couldn't have gone back in time (I was nine or ten, that was legitimately my first thought) so they must have changed it.
But even at that age I was completely dumbfounded as to why...
