The following are Trivial facts relating to Deadman Wonderland.
- Distanced from Current Events: The 'Great Tokyo Earthquake' was changed in the anime to the 'Red Hole Event' as a way to not remind anyone of the then-recent Tohoku Earthquake
. The name "Red Hole" is derived from its depiction as a Nuclear Explosion. - Keep Circulating the Tapes: Not many people knew about the manga when it came out, and due to poor sales, was canceled after five volumes when Tokyopop restructured, which canon-wise is roughly the same time the anime wrapped up. Unfortunate, considering that when the revived Toonami showcased the anime upon its re-launch, interest in the series soared, forcing those wanting to see what happens next to resort to scanlations.
- Network to the Rescue: Viz Media has picked up the manga and has begun publishing new English translations from the beginning as of February 2014. Let the rejoicing begin!

- Playing Against Type:
- Leah Clark as the foul-mouthed Cute and Psycho Minatsuki in the dub.
- Eric Vale as Tamaki. While Eric is no stranger to the Smug Snake roles - Kimblee and Sakyou come to mind - he's still better-known for playing heroic roles, like Trunks, America, and Sanji.
- Real Song Theme Tune: The opening is a variation of Fade's "Black Hearts and Dollar Signs" called "One Reason".
- Also, the ending theme "Shiny Shiny" by Nirgilis.
- Series Hiatus: The manga underwent one in 2012, due to the author's pregnancy.
- Sleeper Hit: The anime adaptation did not do very well in its original Japanese run, and FUNimation picked it up for a cheap buck. When it was announced that [adult swim] would be reviving Toonami as an anime-only block for late-night TV on Saturdays, FUNimation and Williams Street struck a deal to give Deadman Wonderland a premiere-only run, airing episodes 1 through 12 as a promotion for the DVD release. While the first week's episodes weren't anything special, by week two the anime's ratings began to rival those of Bleach, with a few episodes breaking a million viewers.
- Troubled Production: While the anime did get a boost due to the Toonami block, it was very clear that things were not going to plan on the Japanese side of things. For starters, the anime was announced in July of 2009, yet no information started to come out until late February 2011. On top of that, the director, Koichi Hatsumi, even admitted during an interview that the 'first episode was not even done'. Said interview took place a month before the series would premiere. This shows as the animation is of uneven quality, the censorship (and the infamous Dark Rooms) is retained for the home video release, and the Japanese actors themselves seem to give rather uneven performances.
- Early information on the anime series seem to indicate that Azami was initially planned to be adapted, seeing as how the old man from chapter 2 was on one of the earliest character sheets◊, along with Yoh's informant, Chang. However, for whatever reason, this was scrapped (presumably for time constraints), and the design was reused for another unnamed Deadman, Albatross.
