The only films not recommended for the freezer is the polaroid type films, I have kept my film in the freezer for years beyond the exp date with no degration of the film, essentually when you freeze it, you have stopped the aging process, and it works with essentually any type of film except again the polaroid type films, I have some B&W sheet film that I shoot every once in a while that expired in 1975 and it still shoots great.
