Two interesting things here.
If you consider all Kodak production and compare it to Fuji, (including motion picture) then Kodak far outproduces Fuji. BUT, Fuji has much better marketing and distribution, as Kodak seems to have forsaken all of that. See Bob Shanebrook's book for pictures of the huge pallets of film going out the door! Well, it is down a lot, but still going out the door.
And, Kodak is willing to make custom runs if paid for. The problem is not making Kodachrome, it is getting a process for it going. That will double the price.
And then too... Ever hear of Japan Incorporated? The Japanese industry is often supported by the government just like the recent Obama subsidies. Imagine what would happen to EK if the government revived them by giving them an infusion of a few billion dollars.
