Canon is the source material for the DC Extended Universe.
The following is the order in which Canon is referenced:
- On Screen Text
- Deleted Scenes
- Director/Actor Commentary
- Sometimes Novels have fleshed out bits of information that were cut from the film to save on the running time. These can be added in.
- Marketing Websites such as dsrwproject.com and other Viral sites are considered Canon.
- Tie in Comics and Comic Books that are set in the DCEU are considered Canon and their contents to be included as.
- Sometimes writers or producers will give interviews and offer insight into plotlines or details that were not actually revealed on the show. If editors can find an easily-accessible source to verify such information (like a link), it is appropriate to add it to the wiki. (It is not enough to just say "I read/heard somewhere that Christopher Nolan said...")
