Trivia / Mickey's Twice Upon a Christmas

• Acting for Two:
  • In the English version:
    • Russi Taylor reprises her roles as Minnie Mouse and Huey, Dewey and Louie.
    • Tress MacNeille (Daisy), Jeff Bennett (Donner) and Rob Paulsen also voiced elves in the "Christmas: Impossible" segment.
  • In the Latin American Spanish dub, Pluto and Donner are both voiced by Ricardo Tejedo.
• Completely Different Title: In Japanese, the film was renamed Pop-Up Mickey — A Wonderful Christmas.
• Directed by Cast Member: The Latin American Spanish dub's ADR director, Ricardo Tejedo, also voiced Pluto and Donner.
• The Original Darrin: After being replaced by Shaun Fleming for Mickey's Once Upon a Christmas, Jason Marsden reprises his role as Max for this film.
• The Other Darrin:
  • Clive Revill replaced Kelsey Grammer as the voice of the narrator.
  • In the Latin American Spanish dub:
    • Arturo Mercado Jr. voices Mickey Mouse instead of Rubén Cerda.
    • Mario Filio voices Goofy instead of Carlos Segundo.
    • Francisco Colmenero reprises his role as the narrator as with most Disney-related productions. However, his roles of Pluto and Santa Claus are instead voiced by Ricardo Tejedo and Sebastián Llapur, respectively.
  • In the Japanese dub, the late Ichirō Nagai voices the narrator instead of Yuji Machi.
• Real-Life Relative: Arturo Mercado and Arturo Mercado Jr., the respective Latin American Spanish voice actors for Scrooge and Mickey, are father-and-son in real life, although this isn't the first time they've worked together on Disney projects.
• Sequel Gap: Meets the bare minimum, having been released exactly five years after Mickey's Once Upon a Christmas.
• Serendipity Writes the Plot: This was the first major computer animated 3D production from Disney to star Mickey Mouse and his usual co-stars, so not everything was easily rendered to the new dimension. Notably, Mickey and Minnie's ears rotate with their heads, unlike anything 2D that they'd previously been in (they ironed this out in time for Mickey Mouse Clubhouse). Similarly they couldn't realistically render long hair yet, hence why they added Mona as a short-haired new girlfriend for Max to replace Roxanne, complete with the same voice actress.
• Similarly Named Works: There's also a PAX original movie from 2001 called Twice Upon a Christmas
• Suspiciously Similar Substitute: Mona for Roxanne, as they opted to give him a new girlfriend outright rather than cut Roxanne's hair to adapt to technical limitations.
• Unspecified Role Credit: Unlike the film's predecessor, the end credits only list the actors' names and not which characters they voiced.
• What Could Have Been: Several are shown on the DVD.
  • Minnie and Daisy's duel was going to involve baking, decorating, or parade floats instead of figure-skating.
    • The alligators and the hippos are The Artifact from an earlier concept of Donald leading a cavalcade of Disney characters singing the Twelve Days of Christmas, with the hippos being Nine Ladies Dancing and the gators being Ten Lords a-Leaping. Concept art exists of the Mad Hatter as one of the Eleven Pipers Piping, Clarabelle Cow as the Eight Maids a Milking, and Ichabod Crane as one of the drummers.
  • Many ideas were going to be used for the location of the key to the nice list in Christmas Impossible: One such idea was for the Nephews to snatch it from an icy pool guarded by a hungry polar bear. At the same time, many toys were pitched for the decoy keys, but according to Word of God, Jailbreak Bob was chosen because he had the coolest voice.
  • The original concept of Mickey's Dog-Gone Christmas was called "Reindeer Games" where Pluto and other animals got to see how the reindeer trained in order to win a huge supply of dog treats.
    • Deleted Scene: One from the final story was animated before it was cut involving Mickey putting his last flyer on a TV camera, with all the displays showing the Lost Dog flyer.
  • Minnie was going to have her own story involving her being all alone on Christmas Eve before meeting the love of her life: Mickey.
  • Mickey was to have his own story as well to find who stole Minnie's cookies. Concept art of such a segment suggests that it was either the nephews, an idea that got a nod to in Christmas Impossible, Clarabelle Cow, a weasel, or the Big Bad Wolf.
  • The original concept of stringing the stories together was going to be shown in Mickey's house rather than in a pop-up book. Each item that triggered the story would have been part of Mickey's decorating, with Mickey relating the story to Pluto as a Christmas memory, culminating into the opening of Mickey's Doggone Christmas. This was later used in the movie’s comic adaptation.
  • According to one of the writers, Roxanne would have been offhandedly mentioned by Max in the "Christmas Maximus" segment, with the explanation that she dumped Max because of how bumbling and embarrassing Goofy is. This was dropped for two reasons. The first one being because it would have made Roxanne look too superficial, and also because it would have added a dark layer to Max's pleas to his father to act more mature and less intrusive while his new girlfriend is visiting. Given that Goofy basically ignores his son's wishes, it would've made it seem like Goofy is deliberately sabotaging every chance his son has at a romantic life. However, Roxanne did get a mention in the official comic adaptation by Gemstone.
  • Additionally, originally Max's girlfriend in the "Christmas Maximus" segment was going to be Roxanne, but the animation production team found Roxanne's hairdo from A Goofy Movie difficult to animate with the cheap computer animation that the movie had, so she was changed to Mona with a noticeably shorter hairdo. The similarity remains in Kellie Martin, Roxanne's voice actress, also voicing Mona. If that was the primary reason, why didn't the writers simply have Roxanne cut her hair and have Max reference it will be a mystery for the ages. (It does feel like it's a noticably different story if Max's girlfriend already knows Goofy, but that's not the reason they gave.)
  • There was also a story that involved Goofy and Pete competing in some sort of Christmas contest.
• You Sound Familiar:
  • In the "Christmas Maximus" segment, Mona is voiced by Kellie Martin, who previously voiced Roxanne in A Goofy Movie.
  • In the "Mickey's Dog-Gone Christmas" segment, Blitzen is voiced by Jim Cummings, who previously voiced Pete and several one-off characters in Mickey's Once Upon a Christmas.
