John Diggle was created specifically for this series, and was added to the mainstream DC universe starting with the New 52 titles, introduced in "Green Arrow" Issue 24, October 2013. He joins Chloe Sullivan (Allison Mack) from Smallville (2001).
The Queen Mansion exterior shots are filmed at the Hatley Castle in the Hatley Park National Historic Site located in Colwood, British Columbia. This is the same Castle used for the Luthor Mansion exterior shots in Smallville (2001), and for Professor Xavier's castle in the X-Men (2000) film series. The location is also used in Deadpool (2016).
In the comics, Deathstroke (aka Slade Wilson) is an anti-hero with enhanced strength, speed, stamina, and reflexes bordering on superhuman levels according to the comic book profile. He can use up to 90% of his brain, making him a tactical genius and adept at turning an opponent's own abilities against them. He has defeated Batman and Nightwing in combat, and he has given even Wonder Woman a run for her money in a fight.
Each time Oliver revealed his secret, someone's life was in danger (usually, but not always, his own): When Diggle found out, Deadshot had tagged him with a curare laced bullet. When Felicity found out, Oliver had just been shot by his mother. When Barry Allen found out, Oliver had been poisoned. When Tommy found out, Malcolm Merlyn was dying from a gunshot wound. When Merlyn himself found out, he was seconds away from killing Oliver. When Roy found out, another earthquake machine was about to go off and the revelation shocked Roy out of his mirakuru rage long enough to help disarm it. The exceptions to this being Laurel, Moira and Thea.
In Arrow: The Brave and the Bold (2014), when Oliver is introducing Barry Allen to Captain Lance, Lance mistakes his name as Bart Allen. In the comics, Bart Allen is Barry's grandson, who is the sidekick of the second Flash and then eventually becomes the Flash himself.
Felicity Smoak originated as the step-mother of the superhero Firestorm (Ronnie Raymond) in the pre-New 52 continuity in the "The Fury of Firestorm" comics. Later due to her popularity on the show she was re-introduced in the New 52 continuity as part of the "Green Arrow" comics starting with Issue 35 that was released in October 2014. Also for the New 52 version, her appearance is based of Emily Bett Rickards portrayal of her on the show.
Curare is a real paralytic/muscle relaxant that is sometimes used on arrowheads to hunt animals but is mainly used by physicians as an anesthetic. In high enough doses, it can cause respiratory failure and cardiac arrest.
Alex Kingston and John Barrowman both starred as companions to The Doctor in the BBC's Doctor Who (2005). Kingston starred as River Song and Barrowman as Captain Jack. Colin Salmon also appeared as Dr. Moon in two episodes of Doctor Who (also the first appearance of River Song).
The arrowhead design of the title logo has changed every season. Season 1 had a flat arrowhead shape. Season 2 retained the same shape of the arrowhead as season 1, only dimensions were added to it. Season 3 is a completely different arrowhead shape design complete with engraved symbols. A few instances in Season 3 the logo changed to reflect the storyline. In Arrow: Draw Back Your Bow (2014), the title arrowhead logo was that of Cupid's heart shape arrow. In Arrow: The Brave and the Bold (2014), lightning was added to the logo as The Flash guest starred. In Arrow: The Return (2015), the arrowhead logo reverted to the season 2 arrowhead when Slade Wilson returned. In season 4, the arrowhead has a bright green color.
Although Oliver's transformation into The Arrow differs from the original DC comics storyline, it's not very far off. In the comics, Oliver had a fascination with Bows and Arrows from a young age and always had one with him. When he was a young teen, both of his parents were killed. (He was also an only child) When he was 16, he was traveling by sea when his boat crashes and he was marooned on an island with nothing but his bow to aid in his survival. He taught himself to hunt and perfected what little archery skills he had. He grew to be a man and stumbled upon the illegal trafficking of the criminal China White. After putting a stop to her operation, he found his calling as a crime fighter and "borrowing from Bruce Wayne's book" returned home to Star City as the Green Arrow.
The name Isabel Rochev is listed two names down from Adam Hunt (the primary antagonist of the pilot episode) in Oliver's book of names. Isabel Rochev is eventually a reoccurring character played by Summer Glau in season two.
Andrew Kreisberg originally stated that the series is a more realistic take on the character in comparison to the source comic books. Oliver is the only masked vigilante in the world, "there are no aliens and there are no super-villains". This held up more or less, until the decision was made to add the Flash into the equation, which changed everything.
Oliver has mainly two teachers that are responsible for giving him the skills that he uses as The Arrow. Slade Wilson (a.k.a. Deathstroke) who taught him hand to hand combat and melee weapons training and Shado who taught him the bow. Originally in DC comics, Oliver taught himself archery and was taught martial arts by Natas, who was Deathstroke's mentor.
Instead of Brandon Routh playing Ray Palmer (The Atom) the producers originally planned for him to play Ted Kord (Blue Beetle). But CW didn't have the rights to use him so they made the part for The Atom.
Brandon Routh's character Ray Palmer is revealed to be another DC hero, Atom. He, along with Green Arrow (Oliver Queen), Black Canary (Dinah Laurel Lance) and The Flash (Barry Allen), is an existing member of the Justice League of America.
The nursery rhyme for Cyrus Gold (Solomon Grundy) is: Solomon Grundy, Born on a Monday, Christened on Tuesday, Married on Wednesday, Took ill on Thursday, Grew worse on Friday, Died on Saturday, Buried on Sunday. That was the end, Of Solomon Grundy.
In DC comics Roy Harper eventually lost an arm and took a bionic arm substitute; appropriately dubbing himself "Arsenal." Also, DC supervillain Solomon Grundy's real name is Cyrus Gold who appears in season 2 of the series.
For Green Arrow's first two plus decades, he was a relatively minor superhero character, without his own long running comic book series, but in the mid-sixties, the character lost his billions, and got his own series, as more of an earthy people's hero, becoming quite popular, especially when paired with the popular Green Lantern, and also as part of DC's Justice League of America.
In the comics, Dinah "Laurel" Lance is the real name of the heroine, Black Canary. In season one, it's revealed that Laurel's first name is Dinah when Tommy comes up behind her and addresses her as such. In Arrow: Canaries (2015), when Laurel is drugged with Vertigo, Sara refers to Laurel as "Dinah Laurel Lance".
In the comics, Green Arrow had bright blond hair and wore a small mask to hide his identity. Also prior to the New 52 relaunch he had a prominent bright blond goatee, and first wore a Robin Hood style hat, later with no hat, where instead he used a hood. But in the television show, much like his New 52 counterpart, Arrow wears only a green hood (deep and large enough to always cover his face in shadow) and there is no goatee, only stubble. Also instead of a mask he wore some green face paint around his eyes that looks similar to his comic book mask to hide his identity (until the events of Season 2's Three Ghosts where he receives a proper mask), and although he is blond, it is more dark or dirty blond.
Every season the first episode opens up with Oliver running through a forest or some kind of foliage. In seasons 1 and 2 the opening shot is of Oliver running through the forests of Lian Yu. In season 3 it is a line of trees and bushes along a train route. In season 4 he is jogging through a park near his and Felicity's home.
In the comics, Roy Harper has a few superhero monikers, the first of which was Speedy. Though in the series the name belongs to Thea, Roy is referred to by this name at least twice and a couple of times as "Red Arrow", which was his second moniker. Ultimately, Roy takes the name Arsenal which also ties to comic lore.
John Diggle's deceased brother is named Andy, as a tribute to Andy Diggle. Andy Diggle is a writer credited with writing the 2007 limited comic series Green Arrow: Year One. This limited series would come to inspire the creation of the TV series. Andy Diggle also worked on successful series such as Swamp Thing, Thunderbolts, and Daredevil.
Edward Fyers is a recurring nemesis for Oliver Queen on the island. In the comic book series sometime after "The Longbow Hunters", Edward Fyres became a recurring nemesis for Green Arrow. Fyres in the comic book was a mercenary, not unlike the character in "Arrow".
The show is notorious for the frequent shirtless scenes of lead star Stephen Amell. The pilot contained an intense and lengthy workout sequence with Amell shirtless that went viral. Such was the Internet buzz created by Amell's superhero physique that the producers added numerous shirtless scenes to nearly every episode of the first Season. Creator and show-runner Marc Guggenheim called this strategy "absposition" - dumping huge chunks of exposition on the audience while Amell shows of his abs. Amell's abs also became the focus of all marketing and promotion as he was always featured shirtless on the posters and all promo material, stills and trailers always contained shots of Amell shirtless. While admitting that it required a huge effort for him, Amell said he had no problem in flaunting his physique because it contributed to the show's popularity. He said, "Me being shirtless isn't the only element that's made it successful, but it is certainly part of the total equation and I'd be silly to think that it is not." While at Comic-con 2014 to promote the upcoming season of the show, he famously lifted his shirt to show off his abs to the audience getting thunderous applause from the packed auditorium Hall H. The show-runners have also acknowledged the huge popularity of Amell's shirtless scenes and vowed that the show will feature such scenes throughout its run.
The character Shado is based on the femme-fatale with the same name from DC comics. Unlike her onscreen counter part, (who was the daughter of a Chinese soldier and Oliver's archery teacher) Shado was the daughter of a prominent Yakusa (Japanese Mob) agent. She made a career fighting for them and her activities brought her into Oliver's sights after he had become Green Arrow. Shado once tended to a wounded Oliver but copulated with him during his recovery and became pregnant with his first son Robert. In the New 52, Shado was instead retconned as the former lover of Oliver's father Robert and the mother of Emiko, who is Oliver's half-sister.
In the season 3 flashbacks, it's revealed that Oliver was brought to Hong Kong to help bring down China White; whom he was responsible for saving when he prevented her plane from being shot down. This was his first ordeal after leaving the island. This resembles the occurrences of Green Arrow's origins in DC comics. China White ran a drug ring on the island that Oliver was marooned on and his first act as a Vigillante was putting a stop to her operation.
In the comics, Oliver Queen is known for sporting a trademark goatee. Stephen Amell reportedly allowed his beard to grow during the Season 2 hiatus and fashioned a goatee while shaving it and "looked like someone with a record trying to blend into a new city." When asked if his version would ever use the goatee, he tweeted "100% no. Never. Our show could go 14 seasons and a goatee will never appear. Hope that clears things up. Forever." An older Oliver, however, does sport the goatee in Legends of Tomorrow (2016), based on Frank Miller's "The Dark Knight Returns".
The Queen Mansion exterior shots are filmed at the Hatley Castle in the Hatley Park National Historic Site located in Colwood, British Columbia. This is the same Castle used for the Luthor Mansion exterior shots in Smallville (2001), another DC Comics origin story distributed by Warner Brothers and for Professor Xavier's castle in X-Men 2 (2003) and X-Men: The Last Stand (2006).
Sara Lance's hero persona was dubbed simply. "The Canary." And other than sharing the black suit and sonic cry, she is not actually the persona of Black Canary from DC comics. When Laurel takes up the Canary mantle and the name Black Canary, she fulfills her comic book counterparts role.
John Barrowman, Alex Kingston and Summer Glau had recurring guest roles in the series: A Facebook group called "Should Summer Glau Have a Guest Role in an Episode of Doctor Who?" was set up as an online campaign to get Summer Glau (Isobel Rochev) to appear in an episode of the iconic BBC series. Summer Glau played the female Terminator Cameron Phillip in the TV series Terminator: The Sarah Connor Chronicles (2008) and former "Doctor Who" Matt Smith went on to star as Tim in Terminator Genisys (2015). John Barrowman and Alex Kingston both starred in "Doctor Who" as recurring characters Captain Jack Harkness and River Song.
Sara Lance (the first Canary on the show) is loosely based on Dinah Drake; the first Black Canary in the comics. Like her comic book counterpart, she was mainly a very skilled martial artist and did not possess the "Canary's cry."
The character Shado is based on the femme-fatale with the same name from DC comics. Unlike her onscreen counter part, (who was the daughter of a Chinese soldier who helped train Oliver) Shado was the daughter of a prominent Yakusa (Japanese Mob) agent who fought for them and her activities brought her into Oliver's sights after he had become Green Arrow. (Shado once tended to a wounded Oliver but copulated with him during his recovery and became pregnant with his first son Robert.)
In season three, Felicity Smoak reveals her age to be 25, making her character's birth year around 1989. However, the actress that portrays her, Emily Bett Rickards, was born in July 1991. Conversely, Thea Queen's character was born in 1995. However, Willa Holland, the actress playing her, was born in June 1991. She is a month older than Rickards.
Episode no.8 of every season(except the first) has been a crossover episode.[ Season 2: The Scientist (The Flash) Season 3: The Brave and the Bold (The Flash) Season 4: Legends of Yesterday( Legends of Tomorrow & The Flash)]
In Arrow: Taken (2016), Oliver said that he and Mari had an "animated adventure last year". It is the literal truth because most of the Arrow cast provided the voices for their characters in the animated Vixen (2015). Also Grant Gustin and Carlos Valdes from The Flash (2014) stood for their animated characters' voices in Vixen.
Lyla Michaels, of Task Force X, uses the code name Harbinger. Lyla Michaels was a character who aided the Monitor in DC Comics seminal maxi-series, Crisis on Infinite Earths (though both debuted earlier). Lyla is infused with powers and renamed Harbinger.
Originally Emily Bett Rickards (Felicity Smoak) was only supposed to appear in three episodes. However, due to her chemistry with Stephen Amell (Oliver Queen) she became a regular character in the show.
At least once every season modern day Oliver travels to Lian Yu. During Arrow: Pilot (2012), Oliver is discovered in the island. During Arrow: City of Heroes (2013), Diggle and Felicity travel to Lian Yu to find Oliver there. During season 3, Oliver and Thea go to Lian Yu to train for the League only to find Slade out of his cell.
Oliver nicknames his sister "Speedy". In the comics, Speedy is Green Arrow's controversial, drug addicted sidekick Roy Harper. Harper is eventually replaced by Mia Dearden as Speedy. In the third season, Oliver is seen looking for Thea and finds that she has assumed the false name of "Mia". By the fourth season, Thea has replaced Roy Harper altogether, costume and all, and fights alongside her brother.
Throughout season 1 the main character's alter-ego is never actually referred to as The Green Arrow, but rather going by such obscure titles as "the green hooded guy", "the vigilante", or some combination thereof. Only once is "Green Arrow" suggested (by Oliver Queen's nemesis, Malcolm Merlyn), when a group of people at a dining table are discussing what to call this hooded vigilante. Oliver dismisses the suggestion immediately as "lame". It's not until midways into the following season that the name The Arrow starts to appear, and seemed to have stuck. But at the start of season 4, Oliver feels the need to (yet again!) "become something else", and finally dons the name "The Green Arrow".
The series marks the first live-action appearance of Helena Bertinelli/The Huntress (Jessica DeGouw).Ashley Scott portrayed an alternate version of the character, as the meta-human daughter of Bruce Wayne and Selina Kyle, in Birds of Prey (2002).
In Arrow: The Fallen (2015), Thea is revived from the Lazarus pit, but when she awakens she has changed and experiences confusion. In the Batman comics, the second Robin, Jason Todd is revived the same way and like Thea. He has changed and goes through confusion becoming Red Hood.
In the comics, Rose Wilson, daughter of Slade, is a mercenary with an outfit similar to that of Deathstroke, and goes by the name Ravager. In this series, Isabel Rochev dons the outfit although never goes by the same title.
As revealed in an episode of The Flash (2014), in the parallel universe of Earth Two, Oliver was the one to die when the Queen's Gambit sank, leading to his father Robert Queen to establish the mantle of The Arrow.
Towards the end of season 3, Nyssa Al Ghul is forced to marry Oliver in order to provide an heir after his ascension to Ra's. In DC comics, the daughter of Ra's Al Ghul, Talia, does have a genuine love affair with another billionaire/Vigillante that did in fact produce an heir, who's name was Damien Wayne.
The character Curtis Holt, shares the last name of a DC superhero named "Mr. Terrific." Michael Holt, was the second man to don the Terrfic mantle. He was the 3rd smartest man in the world, was a master hand-to-hand combatant and was invisible to all forms of technology. One of his signatures, was the "T-Spheres"; floating Computer/Weapons that Holt controlled mentally. When Felicity inspects Curtis Holt's "world changing prototypes" one of them was a T-Sphere. (Indicating that Curtis might become Mr. Terrific.)
It's implied that Batman exist within the Arrowverse. The fictional city Blüdhaven, Nightwing's City of operations, and several Batman villains such as Firefly, Harley Quinn, Ra's Al Ghul, and Anarky have appeared on the show. In the Fourth Season, Oracle is referenced as a codename Oliver considered for Felicity but chose "Overwatch" as Oracle was taken.
The swords Oliver uses in his fight against Ra's al Ghul in Arrow: The Climb (2014) are called Kris. It s a short sword of Filipino origin. The two Kris in the series were made by Traditional Filipino Weapons.
