This version is unique in that Scrooge meets all three Christmas Ghosts in human form before meeting them as spirits. This situation is similar to the three Kansas farm workers, Miss Almira Gulch, and Professor Marvel in The Wizard of Oz (1939).
In the Christmas Past segment, Scrooge's father going to prison and Scrooge working at the boot factory are taken from Dickens' own childhood and not from 'A Christmas Carol'.
The character of Emily (Scrooge's former fiancée) was addressed as Belle in the book and most other adaptations. This production changed her name in order to avoid confusion with the main character from Disney's Beauty and the Beast (1991) of the same name.
This version is based on a play that was performed in New York for a number of years before being filmed.
During the opening credits a top hatted urchin picks a gentleman's pocket, stealing his pocket watch. He then passes the watch off to a long coated man standing nearby. This is an obvious nod to the Artful Dodger and Fagin from Oliver Twist - also by Dickens.
The boy that gets Scrooge the prized turkey is based on the appearance of the Artful Dodger especially with the top hat while the beadle seen at the Exchange is based on Mr Bumble. Both characters star in Oliver Twist another story written by Charles Dickens.
On his way home Scrooge sees a funeral of the wife of his client Mr Smyth. The funeral could refer to the start of the novel with the death of Jacob Marley who Charles Dickens described as dead a door nail. The funeral may also foreshadow the ghost of Marley and the fate of Scrooge in the future unless he repents.
It is the first live action appearance of the tormented spirits since the 1999 television film of A Christmas Carol (1999) starring Patrick Stewart.
