Pics of the many versions are out there.
I saw "Supernova" in theatres. I was 12 and primed for it. I saw the trailed with "Bats" and was hooked, and having recieved a subscription to Fangoria for Christmas my first issue had "Supernova" as a cover story.
Needless to say, Fangoria had many pictures that did not make the cut. Things not even on the deleted scenes section. One picture had Spader on the "titan" moon examining a "cocooned" mine worker. Spader in the room with the mine worker in the fore ground. Spader prying a "key card" or "ID tag" from the victim. One or two of these are even on the MGM "Supernova" official site in the picture slide show.
What was most interesting was that the actual main photo for the cover story had Karl Larson in a new form of make up. He was white with yellowish scales all over his face and razor sharp teeth smiling if I recall correctly. It appears that in one of the cuts, or one of the "versions" filmed, he morphed into an barely human monster. That leaves a lot of changed story that was disregarded simply for his transformation as it would have been implausible in the theatrical film we see.
At the time I was unaware of the troubles this film had gone through, and it appears that information on it is fairly hard to locate other than mention of Coppolla reshooting or re-editing, or both.
Anyways, I figured I'd share that if people want to find some of these little tid bits they are out there. I believe it was Jan 2000 issue of Fangoria if anyone is curious? After all these years I still find it just as intriguing the hardships and rewrites and lost ideas and abandoned film that was lost...
