Each of the seven princes comes from different fairy tales based in different countries, with the characters' accents matching their backgrounds. Merlin and Arthur, from "The Legend of King Arthur", speak with a Britsh accent; Jack from "Jack and the Giant Beanstalk" speaks with a French accent; Hans from "Hansel and Gretel" speaks with a German accent, and Pino, Noki, and Kio from "Pinocchio" speak with an Italian accent.

More than half of Prince Average's lines were ad-libbed by voice actor Jim Rash which were then incorporated into the film.

The living space of the seven dwarfs has only one wall in front in order to give the illusion that they live in a castle, reflecting their vanity and false pretentiousness.

The triplets are named Pino, Noki, and Kio, referencing the Italian fairy tale Pinocchio, and can be told apart by their hats with one, two, and three belts, respectively.

In May 2017 at a Cannes Film Festival showcase of the film, an ad campaign showing two ladies side by side, one slender and tall the other heavier and shorter came under fire for its controversial tag line "what if Snow White was no longer beautiful and the dwarfs no longer short". Chloe Moretz was quick to defend the movie, saying it had a very positive message. However, when a backlash on social media erupted against the film, Moretz quickly changed her stance and claimed to be "appalled" by the campaign, taking to social media and claiming she had no prior knowledge of the ad's creation and that she was "appalled and angry with the message that it conveyed." The campaign was shortly pulled and a statement from the producers explained that they regret the decision they made in regards to producing the ad.
