Canon refers to the source material that makes up the DC Extended Universe.
Canonical material comes in several mediums, however some have more primacy over others. Listed below is the order in which these take precedence. Additionally, should any newer film material contradict an older film, the newer one shall take precedence.
Information from the films in the DC Extended Universe are the highest precedented canonical material. The following material from them also has a line of priority:
- On-screen text
- Deleted scenes
Tie-in comics and comic books that are set in the DC Extended Universe are considered canon and their contents to be included on the condition they are sourced.
Sometimes novelizations and other books have expanded information that was cut from the film.
Tie-in video games that are set in the DC Extended Universe are considered canon and their contents may be included.
Marketing websites (example here) and other viral sites containing canonical material are welcomed. A hyperlinked citation is required for this.
Film crew/cast will often give insight (eg. press statements, DVD commentary) that offer insight into plot details that were never revealed elsewhere. This is appropriate to add to the wiki on condition that a linked source be cited.
