Canon Policy

The canonical material of the DC Universe can come from different media, mainly from movies and TV shows. In case the most recent content from a series or movie contradicts something established in a previous DCU media, the most recent material uses to take greater relevance.

In the case of a conflict of interest regarding the canonicity of a particular content, an editors consensus must be reached, to decide which scenario is more favorable.

The canonical hierarchy that is commonly used to value in case of a contradiction is the following:

1. Movie/TV Series
   1. The most DCU canonical content there can be, are the projects made by DC Studios.
2. Interviews/Behind the Scenes/Crew Statements
   1. James Gunn's Comments: When James Gunn mentions additional info about a DC Studios production that doesn't contradict the above. However, if a later movie/show contradicts a statement from Gunn, these comments are disregarded and only the later project will be taken into account.
      1. If a film or series presents something, but James Gunn clarifies that it's an error or mentions something different that is more logical and reasonable, Gunn's comment about the film or series prevails.
         1. This is exemplified by the DCEU's The Suicide Squad, where Waller's map showed Corto Maltese in the Caribbean Sea, despite Gunn mentioning that it was located near the coast of Argentina, his intention is clear due to the Argentine accents of the Corto Maltese characters, so the map is interpreted as an in-universe error.
   2. Comments from directors, producers, and writers: Comments made by these people and they don't contradict the previous hierarchy. The same exception above applies when appropriate.
3. BluRay/DVD Bonus Content
   1. If any later project or any of the previous positions contradict this, the previous positions will be taken into account.
4. Games
   1. Games officially produced for the DC Universe and they don't contradict the previus positions.
5. Comics
   1. The information provided in these comics can be considered canon if it doesn't contradict the previous positions. Most of the time, these comics serve as tie-in prequels to the films.
6. Websites and Promotions:
   1. Content despicted in descriptions, titles, etc. on official sites such as DC or Warner Bros. There may be thematic websites are set up to promote a movie or series, content of which can also be considered canon if they don't contradict the above.
7. Novelizations/Visual Guides/Behind the Scenes Books:
   1. Information and details given about the movies in visual books as well as in the novelizations.
8. Visual Artist Commentaries:
   1. Statements about details made by DCU visual artists, these people may receive details of character/item/etc biographies, such as confirmations of item names through concept art.
9. Deleted/Extended Scenes:
   1. As long as what is shown doesn't contradict the above positions, it can be considered canon material within the continuity. Information given in the scripts of DC Studios productions can also be included here, as long as they doesn't contradict the above.
10. Actor Comments:
    1. Information provided by actors from DC Studios projects and they don't contradict previous positions.

There may be occasions where a DCU character is seen in external media, such as Peacemaker appearing in Justice League: Crisis on Infinite Earths – Part One, however if these appearances are not addressed by James Gunn or DC Studios, they cannot be taken as canon.

Likewise, it may be the case that some events from DC Extended Universe productions such as The Suicide Squad, the first season of Peacemaker, or Blue Beetle, are alluded to or hinted at having also occurred in the DCU. In that case, only information based on what is mentioned and shown in the DCU should be added, and it cannot be supplemented with information depicted in the DCEU; the only exception to this rule is when using the same dates, for timeline purposes, as long as they don't contradict the DCU.
