I have some Kodak Supra 400 Professional 35mm that has an expiration date of
May of 2002. Some 18 rolls of it!
So far as I know, it's always been in the refrigerator's crisper drawer..
I have no comfortable assurance it's still good, but will try a couple of
rolls in the next week or so.
I don't have any figures as to how long Kodak says film such as this is safe
inside a 'fridge.
