IIRC, a 5C rise doubles chemical reaction rate, so presumably if your freezer is at 0C (as opposed to 20C), that should slow deterioration by 16X. If it's still sealed in the original foil packets, I'd expect it to be fine. Always assuming there's nothing else going on like ice crystal formation to damage the film (that used to be the limiting factor with batteries, cool was good but if you froze them it damaged them internally). I know that century-old exposed BW film left in a cache by Antarctic explorers and frozen into a block of ice was successfully developed (it had suffered some damage, but I suspect that was from moisture and mechanical damage). >
