I always am keen to see film footage from the past that has been left unacccounted on a shelf or a vault. This is from a report last year about actual color footage taken during the Blitz on London in 1940-41. This is not the newly developed computer-generated colorization process imposed on monochrome film, but the real thing!
The advantage of color film I think brings a sense of heightened reality to any documenatry-style footage. These short intervals of amateur cinema remind us that these events happened among people very much like ourselves, tested them beyond anything most of us who are younger could imagine and brings the words and images of wartime to a deeper level of consciousness.
The people shown in this film footage were a small part of the first military loss dealt to the Third Reich. It is, therefore, a critical record I believe of preserving freedom in the Western World.
