Whatever you do Dave, do NOT make that film Kodachrome. You'll get yelled at for gross continuity errors.

Because of declining demand and it being a complex finicky many-step PITA to process, Kodak discontinued the ISO 25 film in 2002 (and it was hoarded) ISO 200 in 2007 (ditto) and ISO 64 film 1n 2009.

The last K-14 Process lab announced they would shut down that machine at the end of 2010 - their chemicals supplies made it to mid-January 2011.

You still have a roll like that hanging around, all is not lost - BUT. They can only develop it as Black & White, and it'll cost you.
