- Alternative Character Interpretation: Is the Ghost of Christmas Future (portrayed by Pete) really a sadistic asshole? Or is he just acting like one to further scare Scrooge?
- Award Snub: Lost the Best Animated Short Oscar to Sundae In New York, a Claymation musical by Jimmy Picker.
- Awesome Music: Oh What a Merry Christmas Day.
- Critical Dissonance: Siskel & Ebert gave it two thumbs down.
- Evil Is Cool: Pete's Adaptational Villainy version of the Ghost of Christmas Future ends up being one of the memorable portrayals of the Ghost due to just how much Pete oozes in evilness with that role.
- Hilarious in Hindsight:
- Goofy plays the ghost of Jacob Marley in his attempt to warn Scrooge about what will happen if he keeps being greedy. In one episode of Goof Troop ("Wrecks, Lies, and Videotape"), Goofy poses as a ghost to warn Pete about what will happen if he doesn't change his ways. Sound familiar?
- Michael Caine announcing the nominees for Best Animated Short Film, one of them being Mickey's Christmas Carol, becomes hilarious a decade later, when he ended up starring in The Muppet Christmas Carol.
- It's Short, So It Sucks!: Many people wish that Disney didn't try to cram the story into 26 minutes and made it a full length feature instead.
- Older Than They Think: This was largely credited as Alan Young's debut for his role as Scrooge McDuck, but he first voiced Scrooge back in 1974 for the vinyl album An Adaptation of Dickens' Christmas Carol, where he also voiced Cratchit/Mickey and Merlin.
- Squick: Daisy Duck being the ex-girlfriend of Donald Duck's uncle may strike some as being a bit skeevy. Averted in the Finnish dub. Rather than using the Dickens names from the story, the dub instead uses the usual character names, except for Daisy who is instead referred to as "Goldie O'Gilt," Scrooge's old flame from the Klondike Gold Rush.
- WTH, Casting Agency?:
- Goofy as Jacob Marley. Who can imagine sweet, lovable Goofy as a man who once embezzled from the less fortunate? Some could excuse that with the Rule of Funny that scene applies though. Besides, Goofy shorts like Motor Mania and several of the sports-themed entries back in The '50s proved that 'nasty' Goofy could work as a concept. It also works from a metaphorical standpoint—when he robbed the widows and swindled the poor (his words) in life, he done goofed!
- Daisy Duck as Scrooge's past love is also a little odd, given the age difference between the actual characters, unless you take into account that Young!Scrooge's design is based off of Donald's appearance from the 1950 short Crazy Over Daisy.
- Averted in the Finnish dub, where the characters are referred to as the Disney characters portraying the roles, rather than as the Christmas Carol characters they are portraying. A notable result of this change is that Daisy is instead Goldie who up until this point was present only in the comics by Carl Barks.
- Donald Duck as Fred Honeywell. Granted, Donald is Scrooge's nephew, but there's something odd about seeing Donald as such a cheery character that doesn't get angry. Though, when he's in a good mood, Donald can be pretty cheery, and this Fred does get angry, so it's not as unfitting as the others.
- The Woobie: Mickey as Bob Cratchit, true to the original story, has to deal with Tiny Tim's death from an illness. Averted at the end.
YMMV / Mickey's Christmas Carol
