Robert ,

Motion Film Processing with homemix or lab order ECN2 developer widely discussed. I dont know but there can be a anti reflective black carbon layer could be used even at Motion Ektachrome film. I am not sure but lots of motion picture films uses it. If you want to process your film at home , you can remove it after expose and before development . But if you order a processing , this layer disturb your labs processor with a mess. In two cases , you must remove the layer. So before investment , search for the data sheets of that film at kodak com or private message , photo engineer at APUG.

Good luck , I will search the threads and will help you with small list and I will look for the kodak data sheet.
