Diana, as Hanno wrote....this is the case with a lot of WW2 docu's and also movies shown in museums.

One of the pieces of footage you often see is the "staged" German video taken at the location of the Poteau-Recht ambush, even if the docu has nothing to do with the Battle of the Bulge. I have seen it in Normandy Docu's more than once!
Another familiar one is the subject of the British airborne at Pegasus Bridge, where they show footage showing street-fighting with the tell-tale garden fences of Arnhem/Oosterbeek.
