Wow, God I hope it's the original version. Not that I'll be able to see this, but still, perfect follow-up to the Baltimore screening of ANH and it would be awesome to see screen photos.
If this was a true 1980 original, would the print still be in watchable condition after 30 years? Were the post-80 re-releases fresh new prints or were they reused?
For what it's worth, the running time listed is the original....
