Factual error: A toy modern four-door automobile and a clear plastic ball can be seen as the children play when the Burgermeister comes in on his wheelchair. Both unlikely for a story set (presumably) in the 1800's, at the latest.
Factual error: When Edgar the Butler directs the Old Solicitor upstairs they have a bit of a struggle with the steps. Before this you saw the Solicitor arriving in his car and this gave you an impression how high the first floor of the building of the Old Spinster was. Judging by the amount of steps on the stairs the pair would have ended up on the roof.
Factual error: When Scrooge is in the carriage with his girlfriend in the back, on the hill you can see a white van go past.
Suggested correction: I have replayed that scene over and over and I couldn't see a white van pass by.
Same here. I also played it a few times, and I couldn't see it either.
Just watched it. Upper right corner. Just as she sings "give me wings." There is something there but hard to make out what it is.
