This film has an eeriness to it.
All of that fog in the opening scene, how dark and foggy it is when Scrooge is walking home just before he encounters Marley. I imagine that it would have to be very dark once the sun went down back then as there was no electricity.
The Ghost of Christmas Yet to Come is quite spooky in this one. I like how he appears far away surrounded by all of the fog(there's a lot of fog in this one.), and we only see him at a distance or as a shadow. I think it adds to how he's supposed to freak out Scrooge that we don't really get a good glimpse of him.
