An interesting finding. 6 minutes of 8mm amateur film shot in northern Italy during WWII by a German doctor, and left in the freezer since, were developed and shown to the public.
Not particularly exceptional as content - just normal amateur film with people smiling and ordinary everyday scenes - but it is very interesting that they have emerged after so many years, and have been developed and they are useable.
As usual in these cases, the old same flow of rethoric was vented: the eye of the occupier, the "smiling children in the massacred country" and so on. People seem just not to understand that making a 8mm film is a normal activity and there is not a propaganda reason behind it (certainly not for a film in 8mm).
Well, in that article both terms are stated, "frozen" and "refrigerated". I wonder who in 1944 or 1945 would have put a film in refridgeration. Such was not usual. Not even at a commercial lab.
As the OP already hinted at, the article is questionable it its commenting, likely it is so in its stating too.
