- Box Office Bomb: Dreamworks' first. Budget, $95 million. Box office, $76,432,727.
- Creator Backlash:
"Great crew - fantastic dedication of talented people but a doomed mess from concept on. I "directed" on it for almost 3 years but resigned ultimately. The movie has its moments but as a piece of entertainment it's utterly innocuous and forgettable. Yet unless you were there, you'd never know the sheer madness and bloodbath it was to make. If they made a movie of the making of it it would be a cross between Mutiny on the Bounty and The Producers!"
- Animator Will Finn, who directed a bulk of the film has spoken at length about how much he hated making this film, and that he still has nightmares about it to this day. He hated the script and brought it to writer David Swift in the hopes of punching it up, later admitting that he agreed with Swift when he said "You're never going to make a good movie with shit like this for writing!" He fought tooth and nail to keep the game sequence in the film because it was one of the few actual references to something indigenous of pre-colonial Latin America, and the higher-ups could give him no rational reason as to why the wanted it taken out. He jumped ship late in production to return to Disney and had his name removed from the credits, leaving Don Paul and Eric "Bibo" Bergeron (and even an uncredited Jeff Katzenberg) to finish the job.
"Part of my opinion of the movie is tied in with the crazy making of it. I have no particular fondness for it. It was a big missed opportunity as far as I'm concerned. The MAKING of it would make a much more compelling film!"
- Rick Farmiloe, who animated on Tulio for the film, didn't think much of the final film either.
- Creator Killer: After previously composing the The Lion King, the disappointing performing of this film botched the collaboration of composer Elton John and lyricist Tim Rice. They have not collaborated on any film since, and have mainly stuck to theatre. In addition, this was the first in the set of dominoes that made Dreamworks give up on hand-drawn animation until 2015 starting with Dawn of the Croods.
- Dueling Movies: Answer: Daily Double!. The Road to El Dorado is noteworthy for dueling thematically with not one, but two Disney Animated Canon films, with The Emperor's New Groove being the first (in the buddy-comedy in pre-colonial Latin America arena), and Atlantis: The Lost Empire being the second (in the hidden city with riches/Ms. Fanservice lead arena). El Dorado managed to lose to both (it was a clear-cut victory with The Emperor's New Groove, but not so much with Atlantis, which is in the exact same critical range as El Dorado. Atlantis was also a Box Office Bomb, but did end up making more money than El Dorado.
- Enforced Method Acting: In a good way—Kenneth Branagh and Kevin Kline were actually in the recording booth together (which is rare; actors usually record their lines alone with someone else filling in the other characters) so they could play off each other and banter. It worked beautifully.
- Non-Singing Voice:
- Averted; the main characters have the same voice actors for speaking and singing.
- Played awfully straight in all foreign dubbings.
- Stillborn Franchise: This movie was supposed to be the start of a film franchise.
- Troubled Production: As mentioned above, both director Will Finn and a handful of animators have unkind memories of this film, full of stubborn executives and a script they hated. Finn returned to Disney before the movie was even finished. Then there was the matter, as detailed below, of reworking the story very late in production to remove any indication that Miguel and Tulio were a gay couple (which they originally were) resulting in Chel being rush-animated in.
- What Could Have Been:
- If this film had made its money back, we could have a whole franchise of them by now. They deliberately sprinkled the film with sequel hooks, and were already in the early stages of plotting out the sequels. One alternative ending to the film actually had them In Medias Res in their next adventure.
- Tulio and Miguel were originally going to be a gay couple. "Suits" intervened, resulting in Chel's character, and it's rather obvious how she was shoehorned in. All of their homoerotic interactions and jokes? Originally, they were decidedly not jokes. It also explains why Chel actually has very little to the story, and in some scenes her shading doesn't even match up, indicating how late in the production she was added.
- It was also going to be revealed at the end that the armadillo was an angel/spirit sent to help Miguel and Tulio. This makes sense when you think about it, considering all the crazy stuff that happens with it around, including pretty much flying through the ball hoop.
- The movie was originally conceived as an R-rated comedy.
- Chel was going to be a designated sacrifice victim, but the writers didn't want to show the city too soon.
