Although I don't doubt that film can crack at low temperatures, I don't think
that -17C is the point where that occurs in modern day films. I've left
a roll of Kodak Royal Gold in my truck for the past week. Every morning
I've checked the leader for flexibility and cracking, any so far I've been
unable to get it to crack. This morning the temperature was -21C, a bit
colder than the other days, and still the film is very pliable. We're
expecting the temperature to go down to about -24C by mid week so we'll
see if that has any impact.
I searched the Kodak web site for information on this. The only thing I
could find was a reference to shooting movie film stock in low temperatures
(http://www.kodak.com/country/US/en/motion/support/technical/nature.shtml).
They talk about two different film bases, one of which seems to have problems
below the freezing point. Perhaps older 35mm camera film used this as a base.

Yup, that's definitly something to look out for, with low temperatures
usually comes very low humidity which can cause a lot of static electricity.
Advance the film slowly and don't use any kind of a motor drive, especially
to rewind the film.
