I dunno, the first time I saw that trailer I kinda heard the Williams theme when Clark rushed to hold the steel beams on the burning oil rig. Don't know if it was a homage or if Zimmer, when coming up with his Superman sound, just ended up creating a sound that is reminiscent of Williams' theme...but either way I thought it was AWESOME that I was able to hear something that was reminiscent of Williams' theme without feeling like a ripoff. I know the REST of the score doesn't sound like Williams' theme and I would honestly be disappointed if it did....but that little instance, at least to me, does.....and that's not such a bad thing.
