* ContinuityCameo: In episode 8, among the requests the blonde tourist has gathered, there's a doodle of two girls searching for Hanejima Yuuhei - the [[spoiler:Orihara]] twins from the novels. They actually [[LastEpisodeNewCharacter show up in the last episode/second OVA and don't have much plot importance]]. In the same OVA, Mikado also briefly encounters a boy who might be Kuronuma Aoba.
* ContinuityNod:
** There are occasional mentions of Yagiri Pharmaceuticals being at risk of being bought out by an American company called Nebula -- The same Nebula that constructed the [[LightNovel/{{Baccano}} Flying Pussyfoot]] in the 1930s.
** The Dollars website password? LightNovel/{{Baccano}}.
** [[spoiler:[[LightNovel/{{Baccano}} "Hey, Isaac..." "What is it, Miria?"]]]]
** There are also an instance of a clip from Baccano (specifically the fight between Ladd and the Rail Tracer atop a train) playing on a big-screen TV on the side of a building, and again, in the background of one shot was a poster of the Rail Tracer. Both of these instances cause a slight contradiction to the theory that both series are in the same continuity, since Baccano appears to be a TV show or movie in the Durarara era. However, given the existence of Isaac and Miria and Nebula, it could just be a non-fictional movie. But who really knows?
** Ennis from LightNovel/{{Baccano}} again shows up on a big screen in the background during the second OVA/episode 25.
** In volume 5, Shizuo briefly mentions that he once got into a fight with a [[HealingFactor very-difficult-to-injure]] foreigner. BonusMaterial suggests that the man in question is [[LightNovel/{{Baccano}} Nile]]
** In volume 8, Saki mentions meeting an American kid that has [[IdenticalStranger suspicious resemblance to Kasuka Heiwajima/Yuuhei Hanejima]]. The kid in question is Charon Walken, [[LightNovel/{{Baccano}} Chane Laforet]] and [[spoiler:Claire Stanfield]]'s grandson.

** Shizuo: Shizzy, The [[BadAss Gar]]tender
** Celty: [[{{Tsundere}} Tsundullahan]]
** Izaya: {{Troll}}zaya. In Japan he is known as Uzaya from "uzai" which means annoying.
* HeyItsThatVoice:
** Creator/MiyukiSawashiro as Celty Sturluson, and the dub casts KariWahlgren in the role, sounding very much like [[VideoGame/TalesOfSymphonia Raine Sage]].
** Creator/MamoruMiyano as Masaomi Kida
*** And Creator/BrycePapenbrook in English. A short blonde womanizer with HiddenDepths? He's [[VideoGame/FinalFantasyIX basically Zidane]] [[VideoGame/DissidiaFinalFantasy without the tail]]
** Creator/HiroshiKamiya as Izaya Orihara (The way humans won't love me back has left me in despair!!)
** Creator/DaisukeOno as Shizuo Heiwajima (This one is particularly obvious. Ono has such a distinctive talking style one can't help but hear Koizumi...)
*** Creator/JohnnyYongBosch as Izaya Orihara
**** Looking for confirmation on this, but isn't he also the young student who talks to Mikado at the train station at the end of episode 25?
*** Creator/CrispinFreeman as Shizuo Heiwajima
**** This means that Shizuo's both Kyon & Koizumi. Not to mention Alucard. He evens sounds like a more street-thug-like version of him.
**** But Bosch voices Koizumi. Which means Shizuo is Kyon, Koizumi, and...Izayyyaaaaaaa!!!

** SakiFujita as Ruri Hijiribe, even if it is a brief cameo.
** Mika Harima, in English, is voiced by Creator/CarrieSavage- the same voice actor as provided the voice of [[LightNovel/{{Baccano}} Lua]]! It's especially worthy of note in that Carrie Savage is one of the ''only'' English voice actors to appear in both ''LightNovel/{{Baccano}}!'' and ''Durarara!!'', since they're dubbed by different companies (even Isaac and Miria were outfitted with new voice-actors for ''Durarara!!'').
** [[CatchPhrase JUST WHO THE HELL DO YOU THINK]] [[KyleHebert HORADA]] [[Anime/TengenToppaGurrenLagann IS]]!?
** Creator/SpikeSpencer as [[ButtMonkey Saburo Togusa]], [[FreakOut naturally]].

** Creator/YujiUeda as Takashi Nasujima
* NamesTheSame: Kida.
* TheOtherDarrin: [[spoiler:Isaac and Miria in the dub, played by Sam Riegel and Stephanie Sheh.]]
* PlayingAgainstType: The irritable and agressive Shizuo Heiwajima is played by Creator/DaisukeOno, mostly known for playing smooth-talking {{Bishounen}} such as Itsuki Koizumi (TheMelancholyOfHaruhiSuzumiya) and Sebastian Michaelis (''Manga/BlackButler'').
** And Creator/JohnnyYongBosch as [[{{Troll}} Izaya]], this [[Anime/CodeGeass isn't the first time]] he played a ManipulativeBastard.
** Also, Creator/SandyFox, who is well-known to voice [[TastesLikeDiabetes cutesy]], [[NiceGirl kind-hearted]] girls gives you [[spoiler: AxCrazy Yandere [[LoveFreak Haruna Niekawa]]]].
* RuleThirtyFourCreatorReactions: After getting bombarded by calls from his friends over his thoughts on yaoi (thanks to the [[FanPreferredCouple infamous Shizaya pairing]] showing up in ''SayonaraZetsubouSensei''), Narita finally made his stance known in a tweet: [[OneOfUs if he can femslash]] [[SayonaraZetsubouSensei Harumi/Chiri]], then the {{Durarara}} fans can ship whoever the hell they want to too.
** He then decided to screw with the fans by writing a Shizaya story as an April Fools joke. [[http://hi.baidu.com/datacat/blog/item/52c6cbfb1c700b68024f5610.html Found Here]].
* SpellMyNameWithAnS: Invoked in Episode 6 by Togusa, who corrects the semi-conscious goon [[spoiler: when he calls the group "Dollar"]].
** The fansubbers sometimes subtitle the title as "Dullalalah", which is probably the intended translation seeing as the show is about a Dullahan. Artwork is often emblazoned with "DRRR", but fans tend to take it as a quicker way to refer to the series, and not its actual title proper.
*** Technically, ''DRRR!!'' '''would''' be the proper title, given that Narita decided the title the last minute after hearing someone flip through the pages of a book. Since symbols (letters) are made out of ''sounds'' in Japan, it would be デュラララ (lit. ''durarara''). In the west, however, it should be romanized as ''drr''[rrr]. It's even written as such in the second opening credits where all of the names are spelled in English. Durarara, however, is decidedly catchier and easier to say.
** There's also the Dullahan herself, over whom official materials are totally inconsistent. "Certy" appears late in the novels, she herself uses "Selty" on a computer in the anime's fourth episode, and Shinra has her as "Celty" in his cell phone address book in the sixth episode.
** The new opening now gives us the "correct" way to spell the characters names in English.
