From The Guardian in the UK:
The only existing film images of Anne Frank have been loaded on to YouTube by Amsterdam museum the Anne Frank House.
The footage, from 1941, is the only time Anne has been captured on film. The 20-second footage uploaded to the museum’s recently launched Anne Frank Channel shows Anne’s neighbour on her wedding day. A 13-year-old Anne is seen nine seconds into the video, leaning out of a second-floor window to get a better look at the bride and groom. At the time of the wedding the bride-to-be lived at No 37 Merwedeplein, next door to the Franks at No 39.
