!!The original novel:
* CompletelyDifferentTitle: "Alabama Story" in Japan, "The Darkness Beyond the Hedge" in Italy, "The Sun Rises For Everyone" in Brazil.
* FanNickname: Tequila Mockingbird - which is how the title is pronounced if said with a Southern Drawl. It has even been defictionalized - a bar in Virginia offers it as a drink.
* FollowTheLeader: The book ''Wish You Well'' by Creator/DavidBaldacci seems ''just'' a little too similar to this one.
* ReferencedBy: The film is ComicBook/Superman's favorite movie.
** In the ''WesternAnimation/TheSimpsons'' episode ''Diatribe of a Mad Housewife'', Homer expresses disappointment with the book, stating that it only taught him racial tolerance instead of how to kill mockingbirds.
* WhatCouldHaveBeen: Originally Harper Lee wrote a book called ''Go Set a Watchman'' about an adult Scout coming to terms with life in the South as the Civil Rights Movement begins to pick steam. However, her publisher/editor was more intrigued by the childhood flashbacks and asked her to rewrite the book based on those scenes, which became ''To Kill a Mockingbird''. Decades later, the manuscript for ''Go Set a Watchman'' was rediscovered and published.
* WriteWhoYouKnow: Scout was based on Harper Lee's childhood, Atticus on her lawyer father, Jem on her four-year older brother, and Dill on her childhood friend Truman Capote. Boo Radley was based on one of her neighbors (Alfred "Son" Boleware, who was put under house arrest by his father well into adulthood after a teenage vandalism incident), and Tom Robinson was the amalgam of several cases. Ultimately everyone in the book is based off of someone from Lee's childhood. The townspeople were not amused. However, the book was VindicatedByHistory in Monroeville (Lee's hometown). They perform a stage version of it every year with AudienceParticipation for the courtroom scene: the audience is segregated as they were in the courtroom, and twelve men from the crowd are selected as the jury.
* {{Woolseyism}}: The Italian title of the book and movie is 'Il Buio Oltre La Siepe', 'The Darkness Beyond The Hedge', which is a pretty poetic description of the main theme of both works; not just racism, but also fear of the unknown, whatever is in that darkness that is just beyond the hedge that borders the world we do know, [[spoiler: like Boo Radley]].

* BigNameFan: Creator/WaltDisney had the film screened at his personal theater when it was first released and loved it. At the end he told his colleagues that this was the kind of movie [[AnimationAgeGhetto he wished he could make]].
* CreatorPreferredAdaptation: Harper Lee was on set for the first day of filming and was reduced to tears by how well Gregory Peck embodied Atticus Finch.
* DeletedRole: Ruth White's role as Mrs Dubose was heavily cut down, because producers felt her scenes slowed the pace down.
* DyeingForYourArt: Robert Duvall stayed out of the sun for six weeks and dyed his hair blonde, for the role of Boo Radley who, according to the story, spent much of his life as a recluse.
* HostilityOnTheSet: Mary Badham (Scout) and Philip Alford (Jem) didn't get along while filming.
* IAmNotSpock: Mary Badham chose to retire from films after this, so she remained as Scout in the public consciousness. Even Gregory Peck - with whom she remained close friends - continued to call her Scout as an AffectionateNickname.
* LifeImitatesArt: At a couple of points in the movie, Scout, who is only just learning to read, sits on Atticus' lap to visually follow along as he reads aloud. ''Decades'' later, real-life educators began recommending this very technique to parents who wanted to help their youngsters learn to read.
* PlayingAgainstType: Brock Peters had mostly played villains before this film. Here he plays the completely innocent NiceGuy Tom Robinson.
* SelfAdaptation: During the filming, Harper Lee used to come everyday to the set, but stopped after three weeks because by then she knew the movie would be fine without her.
* ThrowItIn: In the film, Tom Robinson's emotional breakdown during his testimony was not scripted. Brock Peters spontaneously started tearing up while filming.
* VacationDearBoy: Philip Alford only auditioned for Jem when his mother said he'd get to miss a day of school.
* WhatCouldHaveBeen:
** Universal wanted Rock Hudson to play Atticus in the film, but he was deemed too young for the part. Creator/SpencerTracy was the director and producer's first choice, but he was unavailable. Creator/JamesStewart was also offered the part, reportedly second, but told the producers he believed the script was "too liberal," and feared the film would be controversial.
** Creator/JamesEarlJones auditioned for Tom Robinson.
