To use your own phrase, "Balderdash, Balderdash, Balderdash".  Film
degrades over time due to chemical processes occurring in the emulsion.
It is a physical law that chemical reactions occur more slowly at lower
temperatures.  Freezing film will DEFINITELY extend its useful life.
You must be careful to let it come to room temperature before using it,
however, to prevent condensation that can damage the film, your camera
and your images.

It is a well-documented fact that Kodachrome has a long storage life *in
cool, dark storage*.  Poor storage conditions will destroy any film,
even Kodachrome.  However, Kodachrome fades faster than Ektachrome when
projected (according to Kodak), so if you intend to publicly exhibit
those stereo shots you might want to re-think your choice of emulsion.
