!!The book
* WriteWhatYouKnow: Dahl said the BFG's made-up words are collected from his wife Patricia Neal's damaged vocabulary after a surgery, in fact they are left in for the parents to understand.
** A television is called a Bunkum Box, which come from the American political term Buncombe.

!!The movie
* AcclaimedFlop: Was well-received by critics but was a box office failure. Did we forget to mention that this movie was directed by ''Creator/StevenSpielberg'', whose name is almost guaranteed to draw audiences to the theaters? It's generally agreed that a lack of a viable star (Mark Rylance and Penelope Wilton aren't Hollywood A-Listers despite being very talented character actors) played a key factor with dismal numbers.
* BoxOfficeBomb: Like many a Creator/RoaldDahl adaptation before it sadly, including Disney's other Dahl adaptation from Spielberg's contemporary Creator/TimBurton 20 years prior, which was ''Film/JamesAndTheGiantPeach''. The film was made on a $140 million budget, yet only made $23.4 million on its opening weekend, making it perhaps the biggest bomb of Steven Spielberg's entire career, after ''Film/NineteenFortyOne''. What couldn't have helped was not only it opening in the midst of ''WesternAnimation/FindingDory''[='=]s red-hot winning streak (something Disney was '''far''' more focused on than ''The BFG''), but also Spielberg's studio having a falling out with Disney executives during production [[http://www.hollywoodreporter.com/news/steven-spielbergs-dreamworks-split-disney-819594 over their increased focus on tentpole films]], and paddling back to Creator/{{Universal}} after having snubbed them for Disney six years before. The box office failure of this movie may have more or less vindicated his decision.[[note]]Perhaps the most tragic part about the movie is that before this film, Spielberg had never actually directed a movie Disney helped produce. This may end up being his only effort with them aside from ''Franchise/IndianaJones 5'' for the foreseeable future.[[/note]]
* ExecutiveMeddling: The film had to be released under the Creator/AmblinEntertainment name instead of the Creator/DreamWorks name due to a mandate from Creator/DreamWorksAnimation CEO Jeffrey Katzenberg that was set up where the name DreamWorks could not be used on a live-action family film, possibly to avoid confusion.
* ScrewedByTheNetwork: Why Disney decided to release this film only '''two weeks''' after ''Finding Dory'' is anyone's guess, though it's plausible that the aforementioned fallout between Spielberg and Disney may have played a hand in this (2016 is also the year of author Roald Dahl's centennial). Plus, Disney has been '''very''' big on supporting projects that can spin out additional films, TheMerch, ExpandedUniverse spinoffs, and so on...whereas this story is a one-and-done case that had no real merchandising possibilities.
