Great to hear someone who actually was there and saw it! I envy you, timdiggerm. When your memory of it is still fresh, can you please take a look at this thread:

...and tell me which picture of the binary sunset and R2-D2 in the canyon best represent the actual print in terms of photography and colortiming, its been some controversy over the years about the film actually being changed already in '93 for its laserdisc release.

Great to hear that the print was still in that good shape, you damn lucky guy! ;)
