The link below is to an amazing video from Yestervid.com of early motion pictures of London, including the oldest (a view of Trafalgar Square) as well as the earliest recording, on Edison wax cylinder, of the chimes of the Clock Tower.
As interesting as it is to see how much has changed in London over the 100-plus years since most of these motion pictures were taken, it is equally interesting to see how much has not changed.
Also great reference for period costumes!
