!!The book
* WhatCouldHaveBeen: In early drafts of the story, the BFG abducted a boy called Jody. It was later changed to a girl, named Sophie after Roald Dahl's granddaughter.
* 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 comes from the American political term Buncombe.

!!The 1987 animated movie:
* ActorAllusion: The boy who dreams that he becomes invisible has a ''WesternAnimation/DangerMouse'' poster in his room. David Jason, who voices the BFG, had provided the voice of Danger Mouse.
* ApprovalOfGod: This was the only film adaptation of one of Roald Dahlís books that he actually enjoyed.
* CreatorPreferredAdaptation: Roald Dahl reportedly stood up and clapped at the end when he first saw it.
* DawsonCasting: Sophie's voice actress Amanda Root. She was twenty-six when she recorded the part.
* DeletedScene: A tie-in book based on the film showed still images of a scene that didn't appear in the final cut. It has Sophie getting separated from the BFG on the way back from Dream Country - getting dropped amongst the rest of the giants by a dragonfly. The BFG rescues her before the other giants wake up, although they do sense a human's scent. The shot of the giants leaving is used in the Queen's nightmare.
* InMemoriam: The animated film was dedicated to the memory of George Jackson, who was an animator that worked on the film, and to the memory of Ballard Berkeley, who provided the voice of the Head of the Army.
* NoExportForYou: Despite being made in widescreen, this film was only released in [[Creator/TheCannonGroup Cannon Cinemas]] in the United Kingdom, running from November 1987 until April 1988. The rest of the world got it as a direct-to-video release.
** It wasn't even seen again in its original aspect ratio until 2012, when it was digitally restored and released on DVD and Blu-ray.

!!The 2016 live-action movie:
* AcclaimedFlop: Was well-received by critics but was a box office failure. 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 (Oscar winner Mark Rylance and Penelope Wilton aren't Hollywood A-Listers despite being very talented character actors) and it being released just weeks after ''WesternAnimation/FindingDory'' played a key factor with dismal numbers. To Spielberg's credit, he's not alone; this is one of at [[Film/{{Matilda}} least]] [[Film/WillyWonkaAndTheChocolateFactory five]] [[WesternAnimation/FantasticMrFox films]] [[Film/JamesAndTheGiantPeach based on a Roald Dahl story]] to become an AcclaimedFlop.
* ActingForTwo: The actors playing the giants also portray the drunken men Sophie complains about at the start of the film.
* AuthorExistenceFailure: In November 2015, Melissa Mathison died of cancer, making this film her last work as a screenwriter.
* 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 then-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.
* InMemoriam: Dedicated to screenwriter and longtime Spielberg collaborator Melissa Mathison. It was her last screenplay before her death in 2015.
* 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.
* WhatCouldHaveBeen:
** Spielberg offered Creator/GeneWilder a cameo, as he had played Willy Wonka in fellow Roald Dahl film ''Film/WillyWonkaAndTheChocolateFactory''. He declined. Sadly, Wilder died weeks after ''The BFG's'' release.
** When the film was first greenlit, Robin Williams was considered to play the titular character.
