History WesternAnimation / OnceUponAStudio

* RightForTheWrongReasons: Before freezing [[Franchise/{{Frozen}} Hans]], Elsa assures her sister that not all the past Disney villains will make it to the photo. While Hans himself can be seen, other villains such as [[WesternAnimation/{{Pinocchio}} the Coachman, Monstro]], [[WesternAnimation/{{Fantasia}} Chernabog]], [[WesternAnimation/OneHundredAndOneDalmatians Horace, Jasper]], [[WesternAnimation/OliverAndCompany Sykes]], [[WesternAnimation/{{Mulan}} Shan Yu]], [[WesternAnimation/{{Dinosaur}} Kron]], [[WesternAnimation/AtlantisTheLostEmpire Rourke, Helga]], [[Franchise/LiloAndStitch Captain Gantu]], [[WesternAnimation/TreasurePlanet Scroop]], [[WesternAnimation/HomeOnTheRange Slim]], [[Franchise/{{Frozen}} the Duke of Weselton]], [[WesternAnimation/BigHero6 Yokai]], and [[WesternAnimation/{{Moana}} Tamatoa]] are not present.

** Zig-zagged somewhat for the core ''Franchise/MickeyMouse'' characters, who look as they did in specific short subjects they appeared in. Most of them appear as they did in ''WesternAnimation/MickeysBirthdayParty'' (1942); WesternAnimation/DaisyDuck wears her outfit from ''Mr. Duck Steps Out'' (1940); WesternAnimation/{{Pete}} wears his "Tiny Tom" getup from ''Officer Duck'' (1939); and [=Scrooge McDuck=] appears as he did while playing Ebenezer Scrooge in ''WesternAnimation/MickeysChristmasCarol'' (1983). Donald's three nephews, however, retain their red, blue and green color schemes from ''WesternAnimation/DuckTales1987'' (even though it was produced by Creator/DisneyTelevisionAnimation and not Walt Disney Animation Studios).

* ArtStyleClash: Every character is animated in a style that reflects their movie or short of origin, but they interact with one another seamlessly. Most obvious is the fact that most characters who debuted earlier than 2005 are 2D-animated while most of those from 2005 and later are CGI, but even within the two mediums, each has the distinctive hallmarks of their era of animation, most obvious in how characters from the 60s, 70s, and 80s have sketchy black outlines (from the xerography process that saved time and money during that era) while 2D characters from before and after that have smoother outlines done in colored ink. Even the 3D characters have some slight differences in the way they're rendered to show the progression of CG technology. And, of course, it all takes place in the live-action Disney animation building.

** Right as may of the characters are about to give up on the photo (for today, at least), [[WesternAnimation/RobinHood1973 Alan-a-Dale]] begins playing [[WesternAnimation/{{Pinocchio}} "When You Wish Upon a Star"]] on his lute (with [[WesternAnimation/TheAristocats Scat Cat]] and [[WesternAnimation/{{Encanto}} Mirabel]] joining in with their respective trumpet and accordion), rousing everyone's spirits and reminding them what they stand for.

* TheVoiceless: Many of the characters don't speak. It's worth noting that some characters featured did not have voices in the first place, like WesternAnimation/OswaldTheLuckyRabbit (a product of the [[UsefulNotes/TheSilentAgeOfHollywood silent era]]) or most of the characters from ''WesternAnimation/{{Fantasia}}'' and [[WesternAnimation/Fantasia2000 its sequel]], being {{Mime And Music Only Cartoon}}s.

** While voicing King Candy in ''WesternAnimation/WreckItRalph'', his very first Disney role, Creator/AlanTudyk had based his performance on Creator/EdWynn's as the Mad Hatter from ''WesternAnimation/{{Alice in Wonderland|1951}}''. His Disney career has now gone full-circle in this short, as he voices the Hatter himself.

* MassiveMultiplayerCrossover: Easily the biggest in Disney history and possibly the biggest ever, with over 500 characters from every Franchise/DisneyAnimatedCanon film, various short films, a few live action/animation hybrid films and even theme park attractions.

''Once Upon a Studio'' is a 2023 combination live-action/animated ShortFilm produced by Walt Disney Animation Studios, viewable [[https://youtu.be/gB90me0aqSY?si=p6vfAsQwZpC2wds8 here]].

Directed and written by Trent Correy and Dan Abraham (''WesternAnimation/OnceUponASnowman''), the film had its world premiere at the Annecy International Animation Film Festival on June 11, 2023, and premiered on Creator/{{ABC}} on October 15th, on Creator/DisneyPlus the next day, and on Website/YouTube on December 24th. Disney also gave it a wide theatrical run by attaching it to a re-release of ''WesternAnimation/{{Moana}}'', followed by a home media release as a bonus feature for ''WesternAnimation/Wish2023''.

* CallForward: [[WesternAnimation/RobinHood1973 Alan-a-Dale]] plays the beginning of [[WesternAnimation/{{Pinocchio}} "When You Wish Upon a Star"]] on a lute, like Sabino will do in TheStinger of ''[[WesternAnimation/Wish2023 Wish]]''.

* ProductionForeshadowing: [[WesternAnimation/Wish2023 Asha]] is one of the featured characters, joining [[WesternAnimation/SnowWhiteAndTheSevenDwarfs Snow White]] and {{Franchise/Mulan|Disney}} for their line of "When You Wish Upon A Star", despite her movie not being released by the time of this short's premiere.

** The absence of Cinderella having a solo line during the reprise of "When You Wish Upon a Star", unlike Snow White, very much implies the aversion of that idea, for better or worse. While some fans may think Cinderella, being Walt's favourite heroine, ''should'' have a line to herself, others may see it as too much of a hard and fast rule.
