The canon of a work of fiction is "the body of works taking place in a particular fictional world that are widely considered to be official or authoritative; [especially] those created by the original author or developer of the world". [2] Canon is contrasted with, or used as the basis for, works of fan fiction and other derivative works. [3]
When there are multiple "official" works or original media, what material is canonical can be unclear. This is resolved either by explicitly excluding certain media from the status of canon (as in the case of Star Trek and Star Wars ); by assigning different levels of canonicity to different media; by considering different but licensed media treatments official and equally canonical to the series timeline within their own continuities' universe, but not across them; or not resolved at all. There is also no consensus regarding who has the authority to decide what is or isn't canonical, with copyright holders usually declaring themselves the authorities when they want to erase or retcon materials that were approved by the setting's original creator (with Star Wars again being an example). The definition of canon is of particular importance with regard to reboots or re-imaginings of established franchises, such as the Star Trek remake (2009), because of the ways in which it influences the viewer experience. [4]
The official Star Trek website describes the Star Trek canon as "the events that take place within the episodes and movies", referring to the live-action television series and films, with Star Trek: The Animated Series having long existed in a nebulous gray area of canonicity. [5] Events, characters, and storylines from tie-in novels, comic books, and video games are explicitly excluded from the Star Trek canon, but the site notes that elements from these sources have been subsequently introduced into the television series, and says that "canon is not something set in stone". [5]
During George Lucas's time with the franchise, the Star Wars canon was divided into discrete tiers that incorporated the Expanded Universe (EU), with continuity tracked by Lucasfilm creative executive Leland Chee. Higher-tier and newer material abrogated lower-tier and older material in case of contradiction. The live-action theatrical films, the 2008 The Clone Wars TV series and its debut film, and statements by Lucas himself were at the top of this hierarchy; such works invariably superseded EU material in case of contradiction. The EU itself was further divided into several descending levels of continuity. [6] After Disney's acquisition of the franchise, Lucasfilm designated all Expanded Universe material published before 25 April 2014 (other than the first six theatrical films and the 2008 The Clone Wars film and TV series) as the non-canonical "Legends" continuity. Material released since this announcement is a separate canonical timeline from the original George Lucas Canon, with all narrative development overseen by the Lucasfilm Story Group. [7]
The makers of Doctor Who have generally avoided making pronouncements about canonicity, with Russell T Davies explaining that he does not think about the concept for the Doctor Who television series or its spin-offs. [8] [9] [10]
The television series The Simpsons has as an example of non-canonical material, the Treehouse of Horror episodes, a series of Halloween-themed specials with several stories that take place outside the show's normal continuity [11]
Several anime television series adapted from manga stories count with some extra episodes with original stories that are not part of the original manga, often being referred to as "filler episodes," being outside of the canon of their source material. [12]
The canonical status of some works by the original writer but not the same publisher, such as "The Field Bazaar", may be debated. [13] This is because copyright used to be exercised by the publisher of the work of literature rather than the author. [14] Campaigning by Victor Hugo led to the Berne Convention which introduced author's rights. [15]
However, sometimes in literature, original writers have not approved works as canon, but original publishers or literary estates of original writers posthumously approve subsequent works as canon, such as The Royal Book of Oz (1921) (by original publisher), [16] Porto Bello Gold (1924) (by estate), [17] and Heidi Grows Up (1938) (by estate). [18]
In film and television it is common that the original writer does not decide what is canon. [19] In literature, the estate of H. G. Wells authorised sequels by Stephen Baxter, The Massacre of Mankind (2017) and The Time Ships (1995). [20] Scarlett was a 1991 sequel to Gone with the Wind authorised by the estate. [21]
In 2010, the Conan Doyle estate authorised Young Sherlock Holmes [22] and The House of Silk . Sequels to the stories by P G Wodehouse about the butler Jeeves were sanctioned by Wodehouse's estate for Jeeves and the Wedding Bells (2013) by Sebastian Faulks and Jeeves and the King of Clubs (2018) by Ben Schott. [23] The Monogram Murders (2014) by Sophie Hannah is a sequel to Hercule Poirot novels authorised by the Agatha Christie estate. [24]
Fan fiction is almost never regarded as canonical. However, certain ideas may become influential or widely accepted within fan communities, who refer to such ideas as "fanon", a blend of fan and canon. [6] [25] Similarly, the term "headcanon" is used to describe a fan's personal interpretation of a fictional universe. [26]
Retroactive continuity, or retcon for short, is a literary device in which facts in the world of a fictional work that have been established through the narrative itself are adjusted, ignored, supplemented, or contradicted by a subsequently published work that recontextualizes or breaks continuity with the former.
Star Wars is an American epic space opera media franchise created by George Lucas, which began with the eponymous 1977 film and quickly became a worldwide pop culture phenomenon. The franchise has been expanded into various films and other media, including television series, video games, novels, comic books, theme park attractions, and themed areas, comprising an all-encompassing fictional universe. Star Wars is one of the highest-grossing media franchises of all time.
A pastiche is a work of visual art, literature, theatre, music, or architecture that imitates the style or character of the work of one or more other artists. Unlike parody, pastiche pays homage to the work it imitates, rather than mocking it.
The Wold Newton family is a literary concept derived from a form of crossover fiction developed by the American science fiction writer Philip José Farmer.
A fictional universe, also known as an imagined universe or a constructed universe, is the internally consistent fictional setting used in a narrative or a work of art. This concept is most commonly associated with works of fantasy and science fiction, and can be found in various forms such as novels, comics, films, television shows, video games, and other creative works.
A sequel is a work of literature, film, theatre, television, music, or video game that continues the story of, or expands upon, some earlier work. In the common context of a narrative work of fiction, a sequel portrays events set in the same fictional universe as an earlier work, usually chronologically following the events of that work.
A crossover is the placement of two or more otherwise discrete fictional characters, settings, or universes into the context of a single story. They can arise from legal agreements between the relevant copyright holders, common corporate ownership or unofficial efforts by fans.
An alternative universe is a setting for a work of fan fiction that departs from the canon of the fictional universe that the fan work is based on. For example, an AU fan fiction might imagine what would have taken place if the plot events of the source material had unfolded differently, or it might transpose the characters from the original work into a different setting to explore their lives and relationships in a different narrative context. Unlike typical fan fiction, which generally remains within the boundaries of the canon set out by the source material, alternative universe fan fiction writers explore the possibilities of pivotal changes made to characters' history, motivations, or environment, often combining material from multiple sources for inspiration. Characters' known motivations may vary considerably from their decisions in the canonical universe. The author of an alternative universe story thus can use the same characters, but send them down different paths to achieve a completely different plot.
The Star Trek canon is the set of all material taking place within the Star Trek universe that is considered official. The definition and scope of the Star Trek canon has changed over time. Until late 2006, it was mainly composed of the live-action television series and films before becoming a more vague and abstract concept. From 2010 until 2023, the official Star Trek website's site map described their database, which listed both animated and live-action series and films as its sources, as "The Official Star Trek Canon".
The term expanded universe, sometimes called an extended universe, is generally used to denote the "extension" of a media franchise with other media, generally comics and original novels. This typically involves new stories for existing characters already developed within the franchise, but in some cases entirely new characters and complex mythology are developed. This is not necessarily the same as an adaptation, which is a retelling of the same story that may or may not adhere to the accepted canon. It is contrasted with a sequel that merely continues the previous narrative in a linear sequence. Nearly every media franchise with a committed fan base has some form of expanded universe.
A spiritual successor is a product or fictional work that is similar to, or directly inspired by, another previous product or work, but does not explicitly continue the product line or media franchise of its predecessor, and is thus only a successor "in spirit". Spiritual successors often have similar themes and styles to their preceding material, but are generally a distinct intellectual property.
The Buffyverse canon consists of materials that are thought to be genuine and those events, characters, settings, etc., that are considered to have inarguable existence within the fictional universe established by the television series Buffy the Vampire Slayer. The Buffyverse is expanded through other additional materials such as comics, novels, pilots, promos and video games which do not necessarily take place in exactly the same fictional continuity as the Buffy episodes and Angel episodes. Star Trek, Star Wars, Stargate and other prolific sci-fi and fantasy franchises have similarly gathered complex fictional continuities through hundreds of stories told in different formats.
A parallel novel is an in-universe pastiche piece of literature written within, derived from, or taking place during the framework of another work of fiction by the same or another author with respect to continuity.
Traditionally, the canon of Sherlock Holmes consists of the 56 short stories and four novels written by Sir Arthur Conan Doyle. In this context, the term "canon" is an attempt to distinguish between Doyle's original works and subsequent works by other authors using the same characters. Usually capitalized by fans of the Sherlockian game as "the Canon", the description of these 60 adventures as the Sherlock Holmes canon and the game of applying the methods of "Higher Criticism" to it was started by Ronald Knox as a playful use of the traditional definition of canon as an authoritative list of books accepted as holy scripture.
The Sherlockian game is the pastime of attempting to resolve anomalies and clarify implied details about Sherlock Holmes and Dr. Watson from the 56 short stories and four novels that make up the Sherlock Holmes canon by Arthur Conan Doyle. It treats Holmes and Watson as real people and uses aspects of the canonical stories combined with the history of the era of the tales' settings to construct fanciful biographies of the pair.
A shared universe or shared world is a fictional universe from a set of creative works where one or more writers independently contribute works that can stand alone but fits into the joint development of the storyline, characters, or world of the overall project. It is common in genres like science fiction. It differs from collaborative writing in which multiple artists are working together on the same work and from crossovers where the works and characters are independent except for a single meeting.
Fan fiction or fanfiction, also known as fan fic, fanfic, fic or FF, is fiction written in an amateur capacity by fans as a form of fan labor, unauthorized by, but based on, an existing work of fiction. The author uses copyrighted characters, settings, or other intellectual properties from the original creator(s) as a basis for their writing and can retain the original characters and settings, add their own, or both. Fan fiction ranges in length from a few sentences to novel-length and can be based on fictional and non-fictional media, including novels, movies, comics, television shows, musical groups, cartoons, anime and manga, and video games.
Star Wars has been expanded to media other than the original films. This spin-off material is licensed and moderated by Lucasfilm, though during his involvement with the franchise Star Wars creator George Lucas reserved the right to both draw from and contradict it in his own works. Such derivative works have been produced concurrently with, between, and after the original, prequel, and sequel trilogies, as well as the spin-off films and television series. Commonly explored Star Wars media include books, comic books, and video games, though other forms such as audio dramas have also been produced.
A continuation novel is a sequel novel with continuity in the style of an established series, produced by a new author after the original author's death.
