All you have all said about motion pictures is true. Except that to preserve the 'film look', all you have to do is shoot in film and then transfer to digital, which is commonly done. You won't be able to tell the difference. So no hundreds of thousands of feet of dupe film to distribute. But yes, many theatres have failed to convert to digital, so they currently DO have to do a lot of film duping.
However, you fail to take into account the magnitudes involved.
No matter how much film the movie industry uses producing and distributing real film, it is nothing compared to annual international consumer sales of Kodak Gold 200 in its heyday (for example). The power of the low-level consumer really moves mountains.
We're 'enthusiasts' - we don't count for much, really! What you and I and everybody else on Pnet / RFF / etc buy and don't buy - a flyspeck.
The movie industry is important to the film manufacturing industry, but not that important. When Kodak chooses to shut down their line, that's it. The movie industry has been warning movie houses for years to convert to digital or risk not getting the latest greatest movies.
Kodak is still producing cine film - in fact, they just announced a new emulsion for the movie industry last week, Kodak Vision 2 50D. Problem is, cine film is not produced in the same manner as photographic still film, and it is truly not that suitable. And why not? All kinds of reasons. Slow emulsions, less forgiving of setting white point, ECN-2 processing not generally available for consumers, spectral sensitivity, grain, and so on. All the things that make a cine film great would tend to make it a lousy choice for still film. Not that it could not be used - just that you'd have to be pretty hard up to want to use it more than once.
I agree that alternatives should be explored - new workarounds tried - and as film finally dries up and become unavailable, we'll probably try any/all of these.
But:
Bill, you seem to forget the motion picture industry, which is not going to suddenly switch to digital capture for their $50,000,000 productions. They will still shoot the raw footage on film.
No, I didn't forget. It just isn't as big a determiner as you may think it is. Kodak cares, of course - this is a money maker for them currently. But when the economics support dumping it, they will. The movie studios are well aware of that. Only the mom/pop movie theaters seem not to have gotten the word. Will it be expensive to convert? Yep. That has nothing to do with it, sadly.
