When Scrooge and Marley offer to buy up the company from Mr. Jorkin, the medium shots show Marley with his hands in his vest pockets, but every close-up has his hands clasped on his stomach.

Early in the movie, Scrooge is complaining about having to give Bob Cratchit Christmas day off with pay. Scrooge puts his scarf on and then Cratchit helps him put his coat on, over the scarf. In the next shot, Scrooge is seen walking outside with the scarf wrapped over his mouth, outside of his of coat.

When Scrooge enters his residence on Christmas Eve, he locks the door and then reaches up and slides a dead bolt so that the door cannot be opened from the outside. The next day, Christmas morning, the housekeeper enters his room while he is still in bed.

The first time the outside door to Scrooge's office is opened, there is no lettering visible on the exterior side of the door's glass. But "Scrooge and Marley", reversed, is clearly visible from the interior side. In later scenes, the outside window is lettered.

When Peter Cratchit is reading from the Psalms, after the camera pans away from him, the voice clearly changes to someone else's. Shortly before the camera pans back to him, the voice changes back to Peter's. This was the voice of Mrs. Cratchit and was meant to show she was thinking about the words he was reading.

Alice seems to age very little between the past and present scenes compared to Scrooge. This could be to show the contrast between the two - she chose to stay on the "good" path and has a healthier spiritual condition, whereas he turned to greed and anger and has prematurely aged.

When Ebenezer first enters his empty house after seeing Marley's face in the door knocker, he picks up an already lit candle in a candle holder. It might have been lit by Mrs. Dilber, who would know when Scrooge comes home.

When Marley dies, he wears his dressing gown, but when he haunts Scrooge as a ghost 7 years later, he wears normal attire. This is because ghosts are many times depicted in their burial clothes, not necessarily the clothing they actually died in (as the wandering spirits appeared in their burial clothes earlier in the movie).

In the Ghost of Christmas Past sequence, the young Ebenezer Scrooge and the older one do not talk nor look alike. People can change a lot in their mannerisms and looks over the years, and Scrooge even more so given that a big point of the film is to show that he went down the "evil" path and now has much deteriorated mannerisms and looks.

When Scrooge calls to the boy in the street to buy the turkey, he leans on the ledge of the window as viewed from the outside. From inside, however, the ledge is seen to be not more than a foot or two up from the floor.

When Marley's ghost shows Scrooge the wandering spirits of the dead outside of his window, one of the spirits is Mervyn Johns as Bob Cratchit, who was very much alive.

Scrooge first enters his bedroom carrying a single candle in a holder. On the door are multiple shadows of Scrooge, carrying the candle. A carried candle cannot cast a shadow of itself.

When Scrooge goes upstairs, he turns to the left at the top of the stairs and goes into his parlor. When he flees the room into his bedroom, he again goes into the room to the left of the parlor. When he is first walking toward the house, there is a vacant lot to the left next to the home. There isn't enough room on the second floor for two rooms on that side of the house unless one room is toward the back of the house.

When Marley joins the wandering spirits, it's the same shot used before, obvious due to the three spirits which just stand around in the lower left.

In an early scene, Scrooge refuses Samuel Wilkins' request for a Christmas extension on his loan repayment by saying, "You'd still owe me £20 you're not in a position to repay if it was the middle of a heatwave on an August Bank Holiday". This refers to a law enacted in 1871.

Brian Worth as nephew Fred flubs a line as he talks to Bob Cratchit. Anticipating the second part of the line ("all the assorted Cratchits") he asks, "How is Mrs. Cratchits...." plural.

On Christmas morning, Scrooge gives Mrs. Dilber a guinea, money which he pulled out of his bathrobe. It seems a bit odd that he would be carrying any money in any sleepwear, and he is never seen going off somewhere to get any money either.

When Scrooge enters Marley's bedchamber shortly before Marley dies, there is an audible wind blowing as he crosses through the outer chamber and up to Marley's bed. The wind stops being heard when Scrooge and Marley converse.

When Ebenezer and Alice are ending their engagement and she gives him back his ring, Alice is wearing a gown with buttons on the front, but there is also a zipper on the back. The zipper was not invented until 1892, initially used on boots, and was not used on clothing until the 1920s.

When Scrooge gives his housekeeper a Christmas bonus and increases her wages to ten shillings a week, she runs down the stairs exclaiming in joy, "Bob's your uncle!" This phrase commemorates British Prime Minister Robert Cecil's appointment of his unqualified nephew, Arthur Balfour, as the Chief Secretary of Ireland, in 1887.

From the ledger dates, costumes, etc., it is clear that the film is set in the 1840s. On a wall in the home of Scrooge's nephew Fred, however, hangs a print of "Monarch of the Glen," an 1851 painting.

Mr. Jorkin quotes the line "Curfew shall not ring tonight" as if it is a well-known phrase. Rose Hartwick Thorpe's poem "Curfew must not ring tonight" first appeared in 1867, and the line did not become popular until around 1900.

A group of coal miners perform "Hark the Herald Angels Sing" in the 1840s. The particular version they're singing wasn't arranged until 1855, when musician William H. Cummings synchronised John Wesley's 1739 verse to the tune of Felix Mendelssohn's 1840 Gutenberg Cantata.

In the film Scrooge has his name on the office door. Offices never had names on doors until the 1880s.

When Scrooge walks into the room of his house and first meets the Ghost of Christmas Present, loud and boisterous laughter can be heard coming from the spirit. This is the kind of laughter that requires someone's mouth to be wide open, yet the spirit's mouth is mostly closed, with a toothy grin.

When the Ghost of Christmas Past says 'Now see yourself in business Ebenezer' his lips do not move.

After Mrs. Dilber has arrived in Scrooge's rooms on Christmas morning, in two clips when Scrooge is looking at himself in a mirror, a member of the crew is also seen reflected in the lower left corner of the mirror. The first clip begins just before Mrs. Dilber says, "Are you quite yourself, sir?" The second begins just before Scrooge says, "Merry Christmas, Ebenezer! You old humbug!"

When Scrooge and the Spirit of Christmas Yet to Come are looking through the window at Bob Cratchit's house, the Spirit's (Czeslaw Konarski's) face is clearly visible for a second.

Bob Cratchit does not recognize the handwriting on the card accompanying the turkey delivered to his house. This makes sense, because in an earlier scene Scrooge asks the boy to bring the butcher and he will tell him where to send the turkey. Therefore the butcher, and not Scrooge, wrote the address on the card. We see Scrooge writing the card himself.

Scrooge would have known that having more bread with his soup would have cost more.
