Nice work on that! I hope it's not too late to request the added feature of audio comparison? Left channel for a mono-ized 1989 and right channel for a mono-ized 2003. The audio changes should be minimal but the speed & pitch may differ between these uploaded sources.

Hopefully, who ever won that film auction some posts back will definitively answer all our questions & guesses. I'm still hoping the 1st, original, and most-awesome 3D (stereographic) theatrical release will turn up. :)
