* ActorAllusion:
** Thea describes Roy Harper as 'Abercrombie-looking'. Guess which company his actor modeled for?
*** Revisited in "Broken Dolls", where Sin also keeps calling him ''Abercrombie''. It becomes her AffectionateNickname for him.
** Barry mentions that [[ICantDance he can't dance]]. [[Series/{{Glee}} Some might disagree]].
** A flashback in "Heir to the Demon" reveals that Mrs Lance was a Professor. Creator/AlexKingston has played a Professor [[Series/DoctorWho before]].
** [[Creator/JohnBarrowman Malcolm]] is BackFromTheDead in Season 2. [[Series/DoctorWho Makes sense]].
** [[SummerGlau Isabel Rochev]] can fight pretty well. [[TheCastShowoff This is probably written into Glau's contract or something]].
* CastingGag: Chin Han, who played a CorruptCorporateExecutive in ''Film/TheDarkKnight'' plays another one in this show (though this time, one who's motivated out of fear of Malcolm after joining [[spoiler:Tempest]] following his daughter being raped while in the Glades).
* CreatorBacklash: A mild example, compared to others -- Stephen Amell has quite happily gone on record with his displeasure over the marketing for Season Two...namely that the posters highlight the ensemble cast, but leave out Paul Blackthorne and Susanna Thompson.
* DuelingShows: With ''[[Series/AgentsOfShield Agents of S.H.I.E.L.D.]]'', as both series fall under the long-standing DCComics[=/=]MarvelComics rivalry.
* FakeNationality
** Stephen Amell, the Arrow himself, is Canadian.
** As is Emily Bett Rickards (Felicity Smoak).
*** Although with both of the above, how "fake" their nationality is depends on the location of [[WhereTheHellIsSpringfield Starling City]] - it could be anywhere in North America.
** Manu Bennett ([[AussiesWithArtillery ASIS commando]] [[spoiler: Slade Wilson]]) is a New Zealander.
** Jessica de Gouw (ComicBook/{{Huntress}}) is Australian.
** Paul Blackthorne (Quentin), Creator/JohnBarrowman (Malcolm) and Creator/AlexKingston (Dinah) are all British, though all three have extensive US experience, with Barrowman holding dual nationality.
* Katrina Law (Nyssa al-Ghul) is American.
* FanNickname:
** Fans have started calling [[http://www.greenarrowtv.com/first-look-at-arrows-huntress/12378 The Huntress]] of this show "ComicBook/{{Catwoman}} with a Crossbow."
** Diggle is the Black Driver.
** Felicity is Bitch with Wi-Fi.
** Roy is Abercrombie.
** Diggle's unborn child has already been named [[Anime/{{Pokemon}} Diglett.]]
* FollowTheLeader: The success of ''Arrow'' not only spawned a [[Series/TheFlash2014 spin-off]], but prompted [[Series/{{Gotham}} Fox]] & [[Series/{{Constantine}} NBC]] to launch their own shows based on DCComics characters, and Creator/{{Netflix}} to partner with Marvel on a series of shows about street level heroes in the MarvelCinematicUniverse. It can even be argued that ''Arrow'''s success is what led to NBC finally going ahead with the revival of ''Series/{{Heroes}}''.
* HeyItsThatGuy: Let's start off with saying that somebody on ''Arrow' must '''really''' have liked ''Series/{{Spartacus}},'' no less than three actors from that show have shown up. Manu Bennett, Katrina Law, and Cynthia Addai-Robinson all appeared on ''Spartacus'' before moving here. Especially interesting is the fact that, unlike [[OnlySoManyCanadianActors other examples of actor-overlap,]] ''Spartacus'' was filmed half a world away in New Zealand.
** Poor [[TheOC Kaitlin's]] family members have a nasty habit of dying.
** [[{{Supernatural}} Benny]] the vampire is a 1%-er now.
*** Speaking of {{Supernatural}}, Gadreel is a mobster.
*** And Ruby is a lawyer.
** Moira Queen was once [[StarTrekVoyager the Borg Queen]]
** [[NipTuck Adrian]] is no less crazy as a drug lord.
** [[{{Torchwood}} Captain Jack Harkness]] is a mean shot with a bow and arrow.
** [[BattlestarGalacticaReimagined Gaius Baltar]] is Dodger.
** [[TeenWolf Jackson]] is no less Abercrombie in this show.
** [[Series/{{Angel}} Charles Gunn]] is a hitman now!
** [[OnceUponATime Dr. Whale]] isn't too nice, either.
** [[SupermanReturns Superman]] is Atom
* HeyItsThatPlace: The house that is used for the Queen Mansion is [[http://en.wikipedia.org/wiki/Hatley_Park_National_Historic_Site Hatley Castle]] in Victoria, British Columbia. It was used for the Luthor Mansion on ''Series/{{Smallville}}'' and Xavier's school in the ''Film/{{X-Men}}'' movies.
* HeyItsThatVoice:
** Quentin Lance is [[WesternAnimation/JusticeLeagueDoom Metallo]].
** [[Creator/KellyHu China White]] is [[WesternAnimation/YoungJustice Cheshire]]. Time will tell if White will develop any interest in Green Arrow's potential protegés.
*** She's also [[{{Film/X2}} Lady Deathstrike]] and [[VideoGame/BatmanArkhamOrigins Lady Shiva]].
** Dr. Lamb is [[WesternAnimation/FantasticFourWorldsGreatestHeroes Reed Richards]].
** [[Creator/KirbyMorrow Matt Istook]] is [[XMenEvolution Cyclops]].
** Thea Queen is [[Franchise/KingdomHearts Aqua]].
** Bronze Tiger is [[WesternAnimation/JusticeLeague Doomsday]].
** Creator/TaraStrong gets a brief cameo as the voice of [[spoiler: Harley Quinn.]]
** The Atom is [[WesternAnimation/TheBatman the Everywhere Man]]
** In the Japanese dub:
*** [[Creator/SatoshiHino Oliver Queen]] is [[LightNovel/TheFamiliarOfZero Saito Hiiraga]], [[LightNovel/ShakuganNoShana Yuji Sakai]] and [[Manga/{{Naruto}} Sai]].
*** [[Creator/SanaeKobayashi Dinah "Laurel" Lance]] is [[Manga/ElfenLied Lucy]] and [[Manga/DGrayMan Allen Walker]].
*** [[KentaroIto Tommy Merlyn]] is [[Manga/{{Naruto}} Choji Akimichi]] and [[Franchise/StreetFighter Yun]].
*** [[KentaMiyake John Diggle]] is [[Anime/MacrossFrontier Bobby Margot]] and [[VideoGame/StreetFighterIV Zangief]].
*** [[NaoyaUchida Quentin Lance]] is [[Manga/{{Naruto}} Madara Uchiha]] and [[Manga/DeathNote Soichiro Yagami]].[[note]]Overlaps a bit with CastingGag.[[/note]]
* IKnewIt:
** Sebastian Blood is [[spoiler:Brother Blood]].
** [[spoiler:Sara Lance]] survived [[NeverFoundTheBody the sinking of the Queen's Gambit]]. Her being Black Canary was also a popular crack-theory not even five episodes into season 1.
** A number of people suggested that due to her brown hair not being a trait inherited from two blonde parents, [[spoiler: Thea wasn't Robert and Moira Queen's daughter. It was revealed in "State v. Queen" that Thea was conceived after an affair between Moira and Malcolm Merlyn]].
** [[spoiler: Malcolm is BackFromTheDead. Okay, technically he never died in the first place, but the point stands.]]
** As soon as [[spoiler:Sara]] asked Oliver "What happened to [[spoiler:Slade]]?" without mentioning [[spoiler:Shado]], people correctly assumed she was killed.
** [[spoiler:Slade's return.]] Given the character's popularity, [[LikeYouWouldReallyDoIt most fans knew he wouldn't be killed like he was]]. Also, since the character is known for being a ''villain'', as soon as they mentioned [[spoiler:what Ivo was looking for and what Brother Blood was doing, many worked out he would be used on Slade and that he was the BigBad]] well ahead of the reveal.
* OneOfUs: Head writers Guggenheim and Kreisberg are big comic fans and love continuity gags.
* TheOtherDarrin: [[spoiler:Caity Loitz as Sara Lance, replacing Jacqueline [=MacInnes=] Wood]] from the Pilot. There's even a FlashbackWithTheOtherDarrin.
* NoStuntDouble: ZigZagged - Stephen Amell does as much of his own stunts as he's allowed, with some of the more complicated[=/=]dangerous stuff being done by a stunt double.
* PlayingAgainstType:
** The [[IceQueen cold-hearted]] Isabel Rochev is well outside of Creator/SummerGlau's usual repertoire, even moreso [[spoiler:now that it's known she's a flat-out villain]].
** The [[MadBomber bomb-happy]], [[StrawNihilist nihilistic]] Shrapnel is a far cry from Sean Maher's previous roles.
* ProductPlacement:
** For Windows 8 and Windows Phone, everywhere.
** All of the laptops are made by Asus.
* WhatCouldHaveBeen:
** Mr. Blank was originally supposed to be the DC Comics villain Onomatopoeia. However, as Onomatopoeia only speaks in, well, [[ExactlyWhatItSaysOnTheTin onomatopoeia]], they couldn't make it work without him coming across as mentally retarded (since sound effects sound far different in real life compared to comic books).
** The twentieth episode of Season Two was originally going to be a BackDoorPilot for a potential spin-off focusing on Franchise/TheFlash. Based on both the strength of Grant Gustin's portrayal of Barry Allen in "[[Recap/ArrowS2E8TheScientist The Scientist]]" and "[[Recap/ArrowS2E9ThreeGhosts Three Ghosts]]" and the fact that using the twentieth episode as a BackDoorPilot would interrupt the show's momentum as it built up to the season finale, the decision was made to make it a standalone pilot.
** In early drafts of Season Two, Sara was originally going to take the role of Ravager, but eventually ended up as the [[ComicBook/BlackCanary Canary]]. Instead, [[spoiler: the role of Ravager was given to Isabel Rochev]].
** The character who was going to buy out Queen Consolidated was originally going to be [[ComicBook/BlueBeetle Ted Kord]], a character whose existence was already implied through the appearance of Kord Industries. However, DC enacted an embargo on him due to "other plans", so the creators instead went with [[ComicBook/TheAtom Ray Palmer]].
