The series pays homage to several zombie media, among other pop culture references.
----
* In the third chapter [[Film/ShaunOfTheDead Shaun]] appears in a convenience store looking as oblivious as ever.
* Kohta Hirano is modeled after the creator of ''Manga/{{Hellsing}}''. Especially blatant when you consider they have the same name.
* A really [[http://www.citymanga.com/highschool_of_the_dead/chapter-23/14/ hilarious one]] of Babiru Nisei, with the characters playing Babiru's cohorts. One with a sock puppet.
* There's another zombie-based franchise abbreviated [[VideoGame/HouseOfTheDead H.O.T.D.]] out there.
* The music that can be heard near the ending of the first anime episode sounds very similar to the theme music of the zombie-esque flick ''Film/TwentyEightDaysLater''. In the fourth episode, there's a sequence with two of the characters riding alone on a motorcycle through the empty, quiet streets, with signs of disarray and violence everywhere, as a song very much like the sad, haunting "Abide By Me" from ''Film/TwentyEightDaysLater'', which did something similar.
* In the anime adaptation, Episode 5 opens with a homage to the [[Film/DawnOfTheDead2004 "celebrity heads" game]].
* At the end of Chapter 17, there's a picture of a man playing with a remote-controlled [[Series/KnightRider KITT]]. Intentional or not, the girl next to him looks a lot like [[Music/{{Vocaloid}} Hatsune Miku]].
* Shizuka and Saya imagine Saeko in The Bride's outfit from ''Film/KillBill'' in Chapter 22.5.
* Shizuka's "[[Film/FullMetalJacket There are only two things that live in Tokonosu!]]" in Chapter 26.
* In the anime, the way the group was separated with the crashing bus brings back memories to those who have played ''VideoGame/ResidentEvil2''.
* The title of Episode 11 of the Anime is "DEAD storm rising". It ends with a U.S. submarine [[spoiler:[[FromBadToWorse kicking off World War III]] with [[AtomicHate nuclear strikes]] against [[UsefulNotes/NorthKoreansWithNodongs North Korea]] and [[UsefulNotes/TheDragonsTeeth China]]]]. [[Creator/TomClancy Sound]] [[Literature/RedStormRising familiar]]?
* For that matter, quite a few of the chapter/episode titles are done the same way.
** [[Literature/AlicesAdventuresInWonderland Alice in Deadland]]
** [[Literature/TheSumOfAllFears The Sum of All Deads]]
** [[Music/GunsNRoses Guns n' Deads]]
** [[Film/TheGoodTheBadAndTheUgly The Good, The Bad, And The Dead]]
** [[Literature/TheRedBadgeOfCourage The Dead Badge of Courage]]
** [[Film/AssaultOnPrecinct131976 Assault on Dead Precinct]]
* Kohta screams "[[Film/{{Zombieland}} Double tap!]]" in Episode 5.
* In the manga: when Saya explains what the side effect of nuclear explosions is, electronic appliances no longer working, there are pictures of said appliances. Among them there is a robot that looks similar to Manga/AstroBoy.
* Zeke, after the end credits of the "Drifters Of The Dead" OVA, giggles like [[WesternAnimation/LaffALympics Mumbly]].
* The propane bomb was a blatant homage to Creator/ZackSnyder's ''Film/DawnOfTheDead2004''.
* In the English dub of the OVA, after Shizuka identifies the burning leaves as hydrangea, Takagi looks back at the beach house and wonders if it's just a front for a drug dealing operation and says, "It's just like Series/BreakingBad!"
