I just 'added' a film from the I.M.D.B. entry as a quick way of finding the F.W.F.R. one. I often do this if I am already on the former and it doesn't cause any problems. However, this time it has duplicated it instead.
I've since watched entries on YouTube claiming to be them, although one was just a shorter version of the other one. It's odd that one of them wasn't on this site earlier -- I would have thought all nineteenth-century films were.
