Besides all the other manufacturers listed above, don't forget that Foma also make a few b+w cine-film materials. Perhaps it might be more accurate to say that Double-XX is the only b+w cine material made in USA.
I meant made by kodak, sorry, that was my stupid brain not being clear.
And it's Double-X not XX
