Alternate Character Interpretation: When Scrooge excitedly greets Mrs. Dilbert, and dances with her, is he showing the same giddiness he was showing to everyone, or was he being passive-aggressive to the woman he now knows would happily loot his corpse.
Big Lipped Alligator Moment: When The Ghost of Christmas Future chased Scrooge around on a black coach. While showing off some nifty 3-D effects and being genuinely spooky (and gave Jim Carrey a chance to adlib), it really didn't do anything to advance the plotline.
Crowning Music of Awesome: The part where the Ghost of Christmas Present takes Scrooge on an aerial tour of Victorian London makes the already magnificent sounds of Hark! The Herald Angels Sing sung by a full professional choir even more epic.
Not to mention "God Bless Us Every One", performed by Andrea Bocelli.
Fridge Brilliance: Marley being stuck as a spirit gains a new explanation in this version. At the funeral scene, the first thing Scrooge does is steal the coins from Jacob Marley's eyes: The custom of putting coins on the eyes of the dead stemmed from a superstition that unless blinded, the dead could open their eyes and seek out others to join them in death, but an even older version of the custom dates back to Greek Mythology: When your soul entered the afterlife, you would be ferried across the River Styx by Charon, the ferryman, who required payment. Two coins were left with the bodies so that they could be used to pay Charon. Scrooge stole Marley's coins, thus Marley can't pay his way, so he is Barred from the Afterlife.
Tear Jerker: When seeing the Christmas Yet to Come, Ebenezer being the only one to see Bob Cratchit's raw, unfiltered, soul-wrenching despair after he hid it from his family. Just staring into that broken face from a man who was so jovial and happy is one of the biggest breaking moments for Ebenezer.
