How does this happen?  There _is_ a silvery film on the film, but how 
does that depolarize the light?  Do you have the polarizer mounted so 
that it's in the light path between the slide and the screen?  Or do you 
have the slide between the polarizer and the screen?

If it's the former, how is the light depolarized?  Unless the material 
makes the light "unpolarizable" (which would seem physically impossible 
to me)...
