The cover of "Baby Mine", used in the teaser trailer, is performed by the Norwegian singer-songwriter Aurora Aksnes, who was on tour in Brazil when she performed the track. This is the first time she contributes to a movie soundtrack. The original rendition was written by Ned Washington and Frank Churchill. It was nominated for a Best Song Academy Award.
There are no talking animals in this adaptation as in the 1941 animated film; instead the story is revised to include more human characters, focusing more so on their perspective, thus one of the three silent white mice that Milly and Joe bring to Dumbo is dressed similar to Timothy.
This is Tim Burton's first live-action remake of a Disney animated film. This does not include Alice in Wonderland (2010) which is a sequel to the original film and not a reimagining of the 1950s animated film.
This is the first live action reboot of a Disney animated feature film that's completely original and not an adaption of anything. The original Dumbo film was based on a children's story, but it wasn't a fairy tale, but a tool for a miniature panorama toy device.
Will Smith declining to star in this film and instead choosing to appear in Aladdin (2019) makes him the second actor to choose a live-action remake of a Disney Renaissance movie over a live-action adaptation of a Walt Disney animated film. Emma Watson was offered the titular role in Cinderella (2015) but chose to play Belle in Beauty and the Beast (2017) instead.
This will be the second live action reboot of a Disney animated feature film to discard the spoken dialogue of the animal characters. The first had been Cinderella (2015) with the title character's mice friends.
