Trivia: The Flash (2014)

  • Acting for Two: With the introduction of Earth 2, we have seen several duplicates of characters, naturally played by the same actors. In fact, Tom Cavanagh is Acting for Four: the late Dr. Wells (in a flashback), the Reverse-Flash (after taking Wells's face and identity), Everyman (appearing as Wells), and "Harry" Wells from Earth 2.
  • Actor Allusion:
    • "Crazy for You" has Barry break out his singing skills.
    • Seeing Captain Cold and Heat Wave (Wentworth Miller and Dominic Purcell) together in the back of a prison van certainly felt like deja vu for some fans, with the end of the episode actually them breaking out of it. Evidently it was Miller's idea.
    • Liam McIntyre playing the Weather Wizard probably alludes to his role as the titular Spartacus whose epithet is "The Bringer of Rain." In the series proper itself, his character loves invoking Battle in the Rain via his Weather Manipulation powers. Further, Mark Mardon becomes the new Weather Wizard after the original one dies, much like how McIntyre himself became the new Spartacus after the original actor died.
    • A couple from "Tricksters":
      • Mark Hamill as James Jesse/Trickster is a Role Reprisal from the 90s show, but there are times where his voice slips into another famous role of his.
      • James Jesse reveals his parentage to Axel Walker in the best way possible.
      • According to Hamill's Twitter page, the trenchcoat Henry wears at the end of the episode is the one John Wesley Shipp wore in the 1990s Flash show.
    • In "All-Star Team-Up," Cisco and Caitlin uttered "Is it a bird?" and "No, it's a plane..." Ray Palmer enters the scene by flying. Brandon Routh, the actor who plays Ray Palmer, also played Superman.
    • In the same episode, Brie Larvan's base of operations is (literally) in a Green(e) house. She also has a B Letter Motif.
    • "Family of Rogues" is full of allusions to Michael Ironside's career:
    • Jefferson "Jax" Jackson sarcastically tells Stein he has the Titanic (1997) soundtrack. Stein's actor Victor Garber had a role in the film.
    • In "Running to Stand Still" the Trickster does a few Christmas carol parodies (plus Dreidel Dreidel Dreidel). Mark Hamill's very first appearance as the Joker in Batman: The Animated Series had him singing "Jingle Bells, Batman Smells." Also worth noting is that the Trickster is in a regular-looking suit with a flower on the left breast, just like the traditional Joker.
    • This also isn't the first time one of Hamill's characters has used explosive dreidels.
  • Casting Gag:
    • Wentworth Miller and Dominic Purcell being cast as Captain Cold and Heat Wave, the first two members of the Rogues. Miller and Purcell previously starred in Prison Break as brothers and two members of the Fox River 8. On top of that, Captain Cold is the emotionally locked-down mastermind of the Rogues, just as Miller's former role Michael Scofield is the emotionally locked-down mastermind of the Fox River 8, and both Cold and Scofield are incredibly meticulous in their plans, to the point of being Crazy-Prepared.
    • Jesse L. Martin once again plays a detective.
    • Clancy Brown as General Eiling, when one of his best known roles is the similarly sinister Lex Luthor.
      • And in that instance, even voiced the Flash briefly (or, more oddly, voiced by the Flash...).
      • And Eiling ends up being dragged away to his presumed death by Grodd, who Lex killed in the DCAU.
      • Brown had also played Grodd on an episode of Robot Chicken, which pays off when Grodd enslaves Eiling's mind and speaks through him.
    • You can't put the guy from The Tomorrow People in a show like this and not expect him to get superpowers too.
    • John Wesley Shipp as Henry Allen, Barry's father. Shipp played Barry in the 1990 series, and Professor Zoom in Batman The Brave And The Bold.
    • When Eobard Thawne is impersonating Wells, he's played by Tom Cavanagh, who played Eli Stone's father; in his original form, Thawne was played by Matt Lescher, who played Eli's brother Nathan.
    • Emily Kinney, who famously played a character named Beth, plays an Evil Counterpart character to Felicity Smoak, who is played by Emily Bett Rickards.
    • One of Brown's best known roles is Lex Luthor in the DCAU (where Eiling was voiced by the similar-sounding J. K. Simmons).
  • The Cast Showoff: Barry sings a few bars of "Summer Nights" in "Crazy For You" after a drunken Caitlin forces him into Karaoke. Grant Gustin sings in real life, starting with a brief stint in a touring production of West Side Story and getting his big break on Glee.
  • Development Gag: The use of "Summer Nights" in "Crazy for You" likely came from an on-set antic on Arrow.
  • Edited for Syndication: On Netflix, Barry's Opening Narration and the Previously On have been cut for some reason.
  • Exiled from Continuity: Geoff Johns stated that Superman and Batman can't appear on The Flash and Arrow because of the movies in development... for now. Despite this, the pilot has a reference to "Wayne Tech."
  • Fake Nationality:
    • Zimbabwe-born Australian Rick Cosnett plays American Eddie Thawne.
    • Canadian Robie Amell plays American Ronnie Raymond.
    • Canadian Victor Garber plays American Martin Stein.
    • Australian Liam McIntyre plays American Mark Mardon.
    • An odd case with the actress(es) portraying Linda Park, who is Korean-American. Her first actress was Olivia Cheng, who is Canadian by birth but whose parents are Cantonese-speaking Chinese immigrants. Her second (and permanent) actress, Malese Jow, is half-Chinese and part-Cherokee... Which gives the implication that Linda has Korean ancestry in the show mixed in with some white background; Jow is Ambiguously Brown enough to pull this off, and nobody is complaining overall.
    • Australian Keiynan Lonsdale plays Wally West.
    • Gambian-English Franz Drameh plays American Jefferson Jackson
    • A possible example with Harrison Wells. Tom Cavanagh is Canadian, and it's never mentioned whether Wells is American or not.
  • Fandom Nod:
  • Fan Nickname:
    • The hidden room of Harrison Wells is called "the Zoom Room of Doom [and Gloom]." Cisco later dubs it the "time vault."
    • Barry's multiple father figures are "Blackdad" or "Copdad" (Joe), "Jaildad" or "Flashdad" (Henry), and "(Shady/Evil) Science Dad" (Dr. Wells).
    • "STAR-Kids" for the Flash's mostly-youthful support team at STAR Labs (with bonus points because Carlos Valdes, who plays Cisco, was a StarKid).
  • Hey, It's That Guy!:
  • Hey, It's That Voice!:
  • I Knew It:
    • The man on fire who does not burn up mentioned by Iris in Episode 6 being Ronnie Raymond.
    • Quite a few people were able to guess that Harrison Wells is the Reverse-Flash before The Reveal in "The Man in the Yellow Suit" based upon various aspects of the character.
    • The fact that Flash was there when Reverse-Flash killed Nora Allen.
    • General Eiling being involved in the F.I.R.E.S.T.O.R.M. project.
    • Mark Mardon being still alive.
    • General Eiling being still alive.
    • Many fans called Ronnie returning as Deathstorm before it was officially announced.
  • I Want You to Meet an Old Friend of Mine:
    • After Wentworth Miller was cast as Leonard Snart/Captain Cold, he was asked if he could think of anyone for the role of Mick "Heat Wave" Rory; Miller suggested Dominic Purcell, his on-screen brother from Prison Break, and the producers took his suggestion. In fact, Heat Wave's introduction is as a former partner of Snart's. Robert Knepper and Peter Stormare have also appeared on Arrow, with Knepper reprising here as well.
    • Robbie Amell and Victor Garber (both halves of Firestorm) previously starred in The Hunters together.
    • Arrow's penchant for casting Spartacus actors carries over here with Liam McIntyre (the titular Spartacus himself) as Weather Wizard.
    • Jesse L. Martin and Andy Mientus were both on Smash.
    • In addition to the Remake Cameo elements with The Flash (1990), Mark Hamill's episode as The Trickster had to include John Wesley Shipp in his recurring role as Henry Allen.
    • Speaking of Hamill, several actors who had voiceover roles in the fellow DC media franchise that was the DCAU have been common. In addition to Hamill (The Joker, Solomon Grundy) reprising his role as James Jessie from both the 1990 Flash show and Justice League Unlimited, both Clancy Brown (Lex Luthor) and Michael Ironside (Darkseid) have had roles in the series as well. Arrow has similarly had Michael Jai White (Doomsday).
    • With Shantel VanSanten and Tony Todd's casting in Season 2, the Arrowverse seems to have a penchant of casting actors from the Final Destination film series as well.
    • Rick Cosnett and Malese Jow were both on The Vampire Diaries together along with Stephen Amell.
  • Jossed:
  • Mean Character, Nice Actor: Behind the scenes and in interviews, it's obvious that Tom Cavanagh is a genuinely lovely guy who is adored by his castmates, as well as an irrepressible goofball. This is a pretty big contrast to the Faux Affably Evil Reverse-Flash.
  • Mutually Fictional: With The Big Bang Theory." Cisco is seen wearing shirts referencing the series, while Sheldon in TBBT'' can often be seen wearing a Flash shirt.
  • The Other Darrin:
    • Linda Park is played in later appearances by Malese Jow. Previously, she was played by Olivia Cheng in her brief Arrow cameo (which was reused in the Flash pilot).
    • A different actor played Mark Mardon in the pilot before he was reintroduced with Liam McIntyre in the role.
  • The Pete Best: Malese Jow is now more remembered as the Arrowverse's Linda Park than Olivia Cheng.
  • Playing Against Type: Tom Cavanagh was primarily known for his comedic roles (JD's brother on Scrubs, Ranger Smith in Yogi Bear) or his friendly roles in comedy-dramas (the brother in Gray Matters, the title character in Ed) before getting cast as the mysteriously sinister Dr. Wells. It's made several of his older roles unintentionally unsettling; listening to his podcast Mike and Tom Eat Snacks with Michael Ian Black is weird now. With the introduction of the Jerkass Dr. Wells (the real one this time) from Earth-2, we get to see another role where Cavanagh fits this trope.
  • Production Posse:
  • Promoted Fanboy:
    • As executive producer, he's already an authority on the show, but DC writer Geoff Johns is notably a big fan of Captain Cold and co-wrote the episode introducing him. Not surprisingly, he's been the best-received villain in the first four episodes.
    • A number of actors are self-professed fans of the show and have later gone on to have guest roles in it, including both Mark Hamill and Matt Letscher.
  • Real-Life Relative:
    • Ronnie Raymond is played by the cousin of Stephen "Arrow" Amell, Robbie Amell.
    • In the Mexican Spanish dub, The Flash and Reverse-Flash's voice actors (Arturo and Mario Castaņeda respectively) are son and father respectively.
  • Role Reprisal:
    • Amanda Pays appeared in "The Man In The Yellow Suit" as Tina McGee, the character she played in the 1990 series.
    • Mark Hamill plays the Trickster, his third time in the role.
    • Vito D'Ambrosio, who played Officer Bellows in the 1990 series, plays Mayor Bellows in "Tricksters."
    • In the Japanese dub, Jun Fukuyama (Barry/The Flash) and Satoshi Hino (Oliver Queen) reprise their respective roles from the dub of Arrow.
  • Shout-Out:
  • Throw It In: Large parts of the Cisco/Wells scene in "Out of Time" were improvised by Carlos Valdes and Tom Cavanagh, such as Cisco crying, and realising he won't survive as soon as Wells shows up.
  • What Could Have Been:
    • The twentieth episode of Arrow's second season was originally going to be a Back Door Pilot for a potential spin-off focusing on The Flash. Based on both the strength of Grant Gustin's portrayal of Barry Allen in "The Scientist" and "Three Ghosts" and the fact that using the twentieth episode as a Back Door Pilot would interrupt the show's momentum as it built up to the season finale, the decision was made to make it a standalone pilot.
    • Linda Park's initial appearance was intended to just be an Easter Egg for the fans, before the writers decided to bring her back in a recurring role.
    • An early draft of the pilot revealed that Hartley Rathaway was initially going to still be part of S.T.A.R. Labs when Barry woke up and (presumably) a main character and member of Team Flash — he would also have been the one to design the suit, with the "design for firefighters" aspect due to having dated a fireman in the past. Presumably, this was removed in order to give Cisco a more substantial role in the plot as well as to get a chance to portray Hartley as the Pied Piper without invoking a Face-Heel Turn.
    • Speaking of which, Andy Mientus auditioned for Barry before being cast as Hartley. Other actors who auditioned for Barry were Matt Barr and James Mackay.
    • Mike Kalinowski auditioned for both Barry Allen and Eddie Thawne.
    • David A. Gregory tested for Eddie Thawne.
    • Keiynan Lonsdale originally auditioned to play Jefferson Jackson for Legends of Tomorrow before the showrunners decided to cast him as Wally instead.
    • Before she was cast as Patty Spivot, Shantel VanSanten was one of the actress considered to play Laurel Lance on Arrow when that show was still being conceptualized.
