The book is known as Sie (meaning She) in German, presumably in imitation of It. Also apt as Paul compares Annie to an African idol in H. Rider Haggard's novel She (published as Sie in Germany).
In Brazil, it was the more indicative Louca Obsessão ("Mad Obsession"). Portugal went for The Foreign Subtitle (Misery - The Final Chapter) as did Italy in a way (Misery must not die).
Creator Breakdown: Stephen King confirmed that the story is about his battle with substance abuse and that Annie is a representation of his dependency on drugs and what it did to his body, making him feel alone and separated from everything while hobbling any attempts he made at escape.
Creator's Favorite: Annie Wilkes is Stephen King's favorite written character because she was always surprising to write, with unexpected depth and sympathy.
What Could Have Been: In his book "On Writing" King admits that when he first started writing Misery, he expected that it would end with Annie murdering Paul, using his skin to bind the completed manuscript of Misery's Return and feeding his remains to her pig. This was also because he'd envisioned it as a short story or novella; as it bloomed into a full novel he decided there was no way people could accept spending all that time with someone going through hell and then not seeing him finally come out on top. note This would explain the random conversation Paul and Annie have at one point regarding Annie knowing how to bind books herself.
King originally was going to title the book, "The Annie Wilkes Edition".
Word of God: Used to giving her characters rich backgrounds to help her find her voice, Kathy Bates and Rob Reiner agreed that Annie was molested by her father as a child. It helped explain for Bates why Annie had a history, as explained in the book and in the movie, of killing infants and old people in her nursing care.
While it's certainly possible that Annie has no computer or cell phone, this would make the cops more likely to investigate her farm first once they realize Paul Sheldon went missing nearby. After all, it's the only place where the owner likely wouldn't be able to call or message anyone. Also it's virtually impossible in today's world for a writer to have only one copy of any manuscript, even if he doesn't particularly like keeping copies. In fact, the entire idea of a writer mostly using a typewriter is hilariously outdated, and yet apparently it's Paul's preferred method, even though word processors and personal computers already existed when the story was written. While Annie did get her Royal from an antique store, almost any antique typewriter today would be unusable, and it would probably be cheaper for her to simply get him a laptop (even in the book, three keys are broken by the time the job is finished). Finally, today's romance novels are widely known as smutty potboilers written by guns-for-hire and read only by lonely middle-aged women, and it's pretty hard to become famous as a writer with them. Also they don't usually shy away from profanity anymore, meaning that they'd be less likely to be a favorite of a woman who prefers terms like "cockadoodie" and "dirty bird" and is offended by actual profanity.
In the book, Paul theorizes that the reason Annie got away with her earlier murders is because she did them in different towns, and police departments weren't able to properly investigate her past doings. Today, police departments have online databases that store all available information on a person's criminal activity, where and when it was done. Annie should have been placed in a prison or mental ward by her late teens.
