Well many tiny (by Kodak or Fujifilm standards) producers were making pretty good color photo films even in the 1960s and certainly in the 1970s.
Not everyone needs a Kodak scale production model to make a happy profit.
AGFA is still making some color film. It can be developed as a negative or reversal. Ferrania certainly has the knowledge and can ramp up. Sunny or Lucky in China and maybe even ORWO or Svema could do it.
For all the stuck people that are concerned that the lower tier producers may not make color film as good as Kodak or Fuji, I say I would rather have a nice supply of Good color film than NO supply of Great color film.
But then I am exstaticaly happy with Kodak Gold and Fujicolor consumer films which I think are amazingly great films for $2 a roll.
