Hi,
I had experience with frozen Kodak High Speed IR film (2x150 ft. rolls my Swiss neighbour donated to me) that had an expiry date of 1985. Was frozen the whole time. Shot some this summer and added, as a precaution, some 0.2% benzotriazole. That took care of the fog and a slight .5 increase in exposure and the negs are great. Of course this is IR film. Your mileage may vary if it is in colour.
Sperm banks keep donor sperm frozen to be used in donor artificial insemination. And it works, most of the time. ;) 

Freezing Good!  ;)

Ciao,
Bogdan

yeah, but don't do that with movie film. It will jam or stick to itself if any moisture is present.

I just got a batch of Foma 200 and Rollei Retro 100 and 400 for my summer's shooting. Should I keep in the fridge? 

    It will do no harm.

    One summer isn't a very long storage time to worry about unless
    you live in a desert shack.

    I am on a one-man crusade to prove it is an urban myth that
    "condensation will damage film if you don't let it warm up
for (variously 1 hour to 1 day)". 
    I make a point of ripping the film from the bowels of the
    deep-freeze, opening it and putting in the camera with
    out any warming and doing so in the humidist place I can find.

    I have had nothing but failure in my attempt to create
    condensation damage.  Requests for examples of condensation
    damage have come to naught.

    My conclusion is that there are better things to do in life than
    waiting for film to warm up.  And writing about film warming up
    is not one of them.  I'm out of here ...  ciao!
