- Adored by the Network: Chances are if you went to a Regal Cinemas location anytime in the summer of 2019 to see a family-oriented films, you couldn't escape promotion for this film. Aside from the normal treatment Paramount films aimed at families get from Regal, note the film sponsored the Stars Of Hope program, had a featurette that ran during the Noovie preshow and was one of a select number of movies featured in the 2019 promo for Regal Unlimited. The trailer even played before some movies not aimed at children or families like Little and Hobbs & Shaw.
- Ascended Fanon: While Dora's parents weren't named in the original television show, here they're called Elena and Cole. Many Go Animate grounded videos featuring Dora had her parents be called Elena and Cole, even predating the movie.
- Cowboy BeBop at His Computer: Due to reports of Michael Bay's involvement (seemingly based on the fact that he cast Isabela Moner in Transformers: The Last Knight), many online assumed he was the director, even though said reports just claimed he was a producer. Then came the revelation that the reports were false and that Bay had no involvement in the production of the film but rather James Bobin directed it.
- California Doubling: Set in Los Angeles, filmed in Brisbane, Australia.
- Dawson Casting: 11-year-old (at the time of filming) Malachi Barton plays 6-year-old Diego. Averted with Isabela Moner, who was 17. The older Diego, Sammy and Randy were played by actors in their early to mid 20s however.
- Edited for Syndication: In addition to the uncensored version, the non-American releases have a censored version that cut the scene of Alejandro taking all his clothes off during the animated Mushroom Samba, though oddly they leave in the later scene where he wakes up and realizes he's naked. Which version is available depends on unknown factors so far.
- Fake Nationality: Due to being filmed in Australia, a number of the minor characters are Australians or New Zealanders playing Americans. Sammy was Hispanic American but played by Aboriginal Australian Madeleine Madden.
- I Knew It!: Many people were able to guess that Alejandro was working with the mercenaries and was using Dora to find her parents and the lost city.
- Meaningful Release Date: The movie was released on August 9, 2019; 5 days before the 19th anniversary of the premiere of the television show - August 14, 2000.
- Multiple Languages, Same Voice Actor: Eugenio Derbez voiced Alejandro Gutierrez for the Latin American Spanish dub.
- Novelization First: The novelization came out on July 2, 2019, roughly a month before the movie's premiere. A few scenes in the novelization, such as one where Swiper claimed to be 65 and living in a studio apartment, don't appear in the film. For instance, the aforementioned "studio apartment" scene became a scene where Swiper is poisoned by the frog Dora introduces us to in the last exploring video she filmed before moving to California.
- The Other Darrin:
- Swiper the Fox is voiced by Benicio del Toro here, instead of his original VA, Marc Weiner. However, Weiner did get to voice the Map again for the opening scene and the animated sequence.
- The Latin American Spanish dub is a meta-example, as the dub of the film was done in Mexico, rather than Venezuela like the TV series.
- The same goes in the Japanese dub:
- Dora is voiced by Honoka Inoue,note , replacing both Chika Sakamoto and Motoko Kumai from the TV series.
- Swiper the Fox is voiced by Sousuke Komori, replacing Junichi Kanemaru.
- Boots is voiced by Kosei Hirota, who is Danny Trejo's regular dub voice in Japan, instead of both Kei Kobayashi and Nami Miyahara.
- Diego is voiced by Ryota Suzuki, instead of Kaoru Shimamura.
- The Other Marty: Micke Moreno was originally cast as Diego, but was eventually replaced with Jeffery Wahlberg due to Moreno leaving the project for personal reasons.
- Production Posse: A lot of the crew members, including director James Bobin, also worked on The Muppets and Muppets Most Wanted.
- Release Date Change: The film was originally scheduled for August 2, 2019, then was moved up 2 days earlier to July 31 before being pushed back to August 9.
- Role Reprise:
- Sasha Toro and Marc Weiner return as the voices of the Backpack and Map, respectively.
- In the Polish dub, Magdalena Wasylik reprises the role of Dora.
- Sleeper Hit: Given that most preschool TV show to film adaptations (and most franchises aimed at or marketed to preschoolers aside from Winnie-the-Pooh's The Tigger Movie and Christopher Robin) have flopped at the box office (the only successful one was Jonah: A VeggieTales Movie due to having no competition from other family films and the franchise it's based off having Multiple Demographic Appeal). On its opening weekend, it beat every single preschool movie not related to Winnie the Pooh with the exception of Jonah, with it surpassing said film three days later.
- Those Two Actors: This film reunites Isabela Moner and Benicio del Toro after Sicario: Day of the Soldado, though a character named Alejandro in this film is played instead by Eugenio Derbez.
