- Christmas Rushed: A typical amount of time for a half hour cartoon to be animated overseas is twelve to sixteen weeks. Cartoon All Stars had to be done in six.
- Keep Circulating the Tapes: Due to the agreement with the various copyright holders specifying limited airings, it hasn't been seen much since its initial broadcast. It somehow managed to get a VHS release as a free rental for families, but the chances of any further releases are slim. Fan uploads on video sharing sites are easy to find if you're not picky about picture quality or legality, though versions that are not the original English version with introduction by George H. W. Bush and Barbara Bush are a bit trickier to find.
- No Dub for You: Unlike Latin America, Spain didn't dub the special in their dialect and they just used the Latin American dub instead. The only replacement done in this version was the inclusion of the then-ruling Queen Sofia of Spain as the respective world leader.
- Not Screened for Critics: Due to the little time the studio had to make the special, they had to forgo typical preview screenings. The only preview they could offer was a 15-minute excerpt (with some music and all sound effects missing) to members of Congress two days before the airing date, with reviewers being forced to wait until air time since the special was still being edited days before.
- The Other Darrin: The special is the first TV or film production in which the classic Looney Tunes characters Bugs Bunny and Daffy Duck were NOT voiced by the legendary Mel Blanc (who had died not long before production began.). He was replaced here by Jeff Bergman, the first of many "new Darrins" who would take over the voices of Blanc's large stable of characters.
- The same goes for many foreign dubs, like the Latin American one: The special was dubbed by a Spanish-speaking dubbing studio in Los Angeles and dubbed by Hispanics and Latin-American expats. This were not a big problem, if not that, at that time, most of the series that appeared there (excluding Garfield, who was dubbed in Chile instead) were dubbed in Mexico by Mexican voice actors and none of the replacements even bothered to sound like their Mexican (and Chilean) peers. The only exception of this rule, in a way, was Daffy Duck, since his L.A. voice actor, Roberto Alexander, voiced him in the Latin American Spanish dub of Who Framed Roger Rabbit.
- This was also one of the first instances in which Jim Cummings provided the voice for Tigger, as Paul Winchell had recently retired.
- Unintentional Period Piece: The special itself has actually aged rather well. There isn't any major slang, fashion or fads present to keep it tied down to the 90s. The only things keeping it linked to the time period are the introductions by the then-current world leaders (the original U.S. version features President George H. W. Bush and First Lady Barbara Bush; they were out of office by 1993) and the fact that it uses popular cartoons from the time, and even that isn't much of a problem since most of them are part of franchises that are still popular and highly recognized to this day.
- What Could Have Been: Mickey Mouse, Goofy and Donald Duck were originally planned to appear, but they were replaced by Huey, Dewey and Louie. If they had gone through with the original concept, it would have been the second time Mickey and Bugs were together and Donald and Daffy together since Who Framed Roger Rabbit. The producers of Cartoon All-Stars probably didn't want to deal with the headache of making sure each pair had exactly equal screen time as Roger Rabbit was forced to do.
- When Joe Biden asked Richerd Frank if there was a sequel in the works and with George C Scott returning as the villain he states, "It will depend on the reception of the special". Sadly it never happened.
