The only known surviving image of Anne Frank in a moving picture was apparently found and is now being shown at the Anne Frank House in Amsterdam. I visited the house where the family was hidden and eventually discovered by the Nazis a few years ago and found it to be a very deeply emotional experience.
In this very brief 20 second film clip, little Anne is leaning out of her window to get a good glimpse of her neighbor who was getting married. You can see her little bobbed head craning to get the best view possible. It's quite humbling to see the peaceful setting, the people going about their daily lives (just as we do now) never knowing their fate. In a few months these streets would be filled with marching soldiers and their homes looted and most being marched off to their sure deaths.
