Yes you can process Kodachrome as a black and white negative. Have a look at the following thread, especially posts 10 and 11 which are very detailed descriptions of developing Kodachrome cine film. http://www.apug.org/forums/forum40/5...e-b-w-neg.html.
Note that unlike E6 (slides) and C-41 (colour neg) films, Kodachrome has a backing layer (remjet) which must be removed before processing. Search the threads here - there is loads of info about Kodachrome films, still and moving.
