Corrected entry: In all the scenes of Victorian London, aside from some green liquid in the streets, there is no litter, no filth. Everything is far too clean.
Corrected entry: Near the end where Nancy has just been murdered by Bill Sikes, as Bill runs off with Oliver, they switch to a shot of policeman and other people running up and finding Nancy's body. When they do this, take a look a Nancy - both of her legs move. You won't even have to look very hard, it is quite obvious.
Correction: This is Nancy writhing in pain as she takes her dying breaths and there is nothing that can be done to save her. It's too obvious to be unintentional.
Correction: 'All the scenes'? So what about the open sewer in front if the three cripples pub? And the alley and stairs leading to Fagin's hideout? The ones that are sinking into the filth and unable to support the crowd chasing Sykes, and where Fagin loses his valuables at the climax? The submitter may not be aware that this is actually raw sewage flowing through the streets of London to the Thames. There are plenty of shots and scenes showing the filth and squalor of 19th century London. The more well-to-do areas are depicted as comparatively cleaner, which they actually were. The film is a stylised musical, not a documentary.
