!!''Literature/TheHobbit'' (book)

* AshcanCopy: The [[https://www.youtube.com/watch?v=UBnVL1Y2src 1966 short film]] directed by Gene Deitch, was made for this purpose (more info [[http://genedeitchcredits.com/40-william-l-snyder/ here]]). According to Deitch it was screened only once in June 1966 to an audience of about six people to fulfill the part of the contract saying the film had to be shown in public. Despite being the ''only'' screen adaptation of Tolkien's work produced when he was still alive, he never saw it (leading Deitch to say [[CreatorBacklash "Thank God!"]]). The story included a Princess for Bilbo to romance, and discarded many basic elements of the story, such as the dwarves. Gandalf ceased to play a part after they depart for the Lonely Mountain. Characters were renamed (Trolls became Groans, Goblins = Grablins, Gollum = Guloom) and the dragon Slag (not Smaug) is dispatched by Bilbo, the Princess and her retainers.
* BreakthroughHit: The success of ''The Hobbit'' encouraged Creator/JRRTolkien to write a much larger novel about Middle-Earth, which turned out to be ''Literature/TheLordOfTheRings''.
* RecycledScript: In ''The History of the Hobbit'' it's pointed out that Thranduil the Elvenking and his hold in Mirkwood is closely derived from the original conception of Thingol of Doriath (Tinwelint of Aranor) -- which also [[FridgeBrilliance explains his distrust of dwarves]]. This isn't obvious to people who are only familiar with the published ''Silmarillion'', because the final version made Thingol and Doriath much richer and less earthy and sylvan. However, Tolkien added a DiscontinuityNod to this when ''Literature/TheSilmarillion'' does mention that Thranduil lived in Doriath in his youth and modelled his own kingdom in Mirkwood on it.
* ReferencedBy: The source code for Perl 5, which does quote ''Literature/TheLordOfTheRings'' many times, also quotes ''The Hobbit'' once, at the top of [[http://perl5.git.perl.org/perl.git/blob/HEAD:/numeric.c numeric.c]].
* WhatCouldHaveBeen: ''The History of the Hobbit'' is full of these.
** The first draft sets the story in the time of ''Literature/TheSilmarillion'', while in another, Bilbo mentions China and the Gobi Desert at some point, implying the story takes place in our own world instead of the Middle Earth.
** Beorn was originally called "Medwed" (Russian for "bear"), Gandalf's name was originally to be "Bladorthin", Thorin's name was originally to be Gandalf, Smaug was to be "Pryftan", and Bilbo's working first name was "Bingo".
** Originally, Gollum bet his ring on the riddle game and freaked out after finding it was missing precisely because he couldn't keep his promise. He showed Bilbo the way out vountarily and they parted away in good terms. This idea actually became canon and were printed on the original 1937 to 1951 editions of the book. It was only changed after Tolkien decided to weld ''The Hobbit'' with ''The Lord of the Rings''.
** Plot-wise, the most drastic change was about Smaug, specifically that Bilbo killed him instead of Bard. In the earliest draft, Bilbo killed Smaug with a spear while the dragon was sleeping, while in the second and most developed one, the first time Bilbo infiltrated Smaug's lair he would stab him through the bare spot in his chest with Sting (which went so deep it vanished completely), and then ''ride a golden bowl on the stream of blood pouring out of Smaug's wound'' before triumphantly exiting the mountain. Tolkien decided to change it and invented the character of Bard to kill Smaug in a slighty more credible way.
