- Celebrity Voice Actor: In the Japanese dub, Holt is voiced by the movie actor Hidetoshi Nishijima, who some anime fans would recognize him as the voice of Kiro Honjo in The Wind Rises.
- Fan Nickname: Water For Flying Elephants
- Fake American: Irishman Colin Farrell does a rather fluent American accent for Holt Harrier. Nico Parker and Finley Hobbins (Millie and Joe) are also actually Brits doing American accents.
- Name's the Same: The name of Vandevere's amusement park is Dreamland.
- Playing Against Type: In stark contrast to the bulk of his filmography, which consists of very dark films with a few comedies sandwiched in, this is probably the most family friendly and lighthearted of Tim Burton's films next to Pee-wee's Big Adventure.
- Production Posse: This is the fourth Tim Burton movie that Michael Keaton and Danny DeVito have appeared in each (and it's a "Batman Returns Reunion" of sorts for the three of them), and the third for Eva Green. It's also Alan Arkin's second collaboration with Burton since Edward Scissorhands and his first one since Arkin's Career Resurrection in 2006. Composer Danny Elfman, production designer Rick Heinrichs, film editor Chris Lebenzon and costume designer Colleen Atwood returned to collaborate with Burton once more.
- Undermined by Reality: Disney puts out a movie about the evils of corporate mergers... just days after concluding a massive deal to buy out 20th Century Fox, and immediately started massive lay-offs. This was not lost on professional critics.
- Very Loosely Based on a True Story: Dreamland was a real amusement park on New York City's Coney Island owned by real estate developer William H. Reynolds. The park opened in 1904 and was very sophisticated and high-tech for its day. In 1911, an accident while attempting to repair an electrical malfunction started a huge fire that destroyed most of the park and the park was never rebuilt. The movie's Dreamland is based on the real-life Dreamland, from the demonstrations on future technology down to the sideshows (including an act featuring a clown firefighting troupe responding to a skyscraper fire) to the park's destruction. Unlike the real-life events:
- The owner's name was changed to V.A. Vandervere and was depicted simply as a smug, unethical promoter indifferent to others and the safety of his animals.
- The fictional Dreamland was destroyed in 1919, eight years after the real park was destroyed.
- The real-life Reynolds was able to recoup his losses by selling the land where Dreamland once stood and cashing in on outstanding bonds. In the movie, Vandervere's future is unclear, as he is last seen watching the park being destroyed by the fire.
- The cause of the fire is also fictionalized. The real-life fire was caused by an accident as electrical repairs were being made to the Hell's Gate attraction. In the movie, Vandervere — in trying to stop the Medici troupe from helping Dumbo's mother escape execution note — in a panicked moment of overzealousness attempts to restore power to the park but completely overloads the electrical system.
