my information might be outdated, but as far as a know, the lowest volume kodak can make is 312900 feet. this ads up as follows: one emulsion batch will give enough emulsion to coat 3 master rolls. one master roll is 54 inches wide and 3000 feet long. they ditch 20 millimeters on both sides, so in case of 35mm you will get 38 streaks, witch is 104310 feet for one master roll. that might sound an unimaginable amount in photography, but it is barely enough to support even a mid-sized motion picture shot on film (for the sake of this argument, let's assume that that production uses only one type of emulsion).
i might be too optimistic, but i think today everyone who wants to use digital has been doing so already (in both the photography and motion picture industries). so, unless the disappearence of print films, or kodak themselfes screw production up... we might be okay. in other words, if kodak motion picture film survives the next 2-3 years, it will survive the next twenty.
