The Flash is an upcoming TV series developed by Greg Berlanti, Andrew Kreisberg and Geoff Johns, to air on The CW. It will be based on the DC Comics character Flash (Barry Allen) tobe played by Grant Gustin, a costumed superhero crime-fighter who was created by Robert Kanigher, John Broome and Carmine Infantino. It is a spin-off to Arrow, existing in the same universe. The pilot for the series was written by Berlanti, Kreisberg and Johns, and directed by David Nutter. The series was officially picked up on May 8, 2014.
Heres a short plot:
After witnessing his mother's murder, and his father wrongly accused, Barry Allen is taken in by Detective West and his family. Becoming a forensic scientist for the Central City Police Department, Allen tries to uncover the truth about his mother's murder, which leads him to Harrison Wells' particle accelerator. When the accelerator causes an explosion, Allen is struck by lightning, and enters a coma. When he wakes up, he learns he has the ability to move at superhuman speeds, though he is not the only metahuman created in the wake of the explosion.
Barry in "Arrow" TV Series
Barry makes his first appearance in the second season of Arrow "The Scientist" (episode 8) as a CSI from Central City who has come to Starling City to investigate a possible super being that he claims may have connections to a case in Central City. He meets with Oliver Queen (Stephen Amell) after Queen Consolidated is burgled. Barry and Oliver's confidante, computer science expert Felicity Smoak (Emily Bett Rickards) have an immediate rapport, but Oliver, who is the secret identity of the vigilante known as "Arrow", is suspicious of Barry. Barry reveals that he is attempting to find a super-powered being who killed his mother when he was a child, leading to his father's wrongful imprisonment. Barry is ordered back to Central City, but is instead brought to Oliver's hideout by Felicity and John Diggle (David Ramsey) after Oliver is accidentally injured and poisoned. In the following episode, "Three Ghosts", Barry saves Oliver's life, and continues to assist Felicity with tracking down Cyrus Gold (Graham Shiels), a test subject of Sebastian Blood (Kevin Alejandro). He returns to Central City, leaving behind a custom-made domino mask for Oliver as a better way of concealing his identity. Having returned to Central City, he is caught in a chemical explosion at a lab caused by a combination of a lightning strike and the explosion of the S.T.A.R. Labs particle accelerator across town. In "Blast Radius", it is revealed that Barry was left in a coma following the lab accident. In "The Man Under the Hood", Caitlin Snow and Cisco Ramon are seen taking inventory at the Starling City facility of S.T.A.R. Labs due to Harrison Wells shutting it down, when Deathstroke (Manu Bennett) arrives to acquire a bio-transfuser. It is revealed that Barry has been under Caitlin and Cisco's watch at S.T.A.R. Labs when his condition worsened, and they later help Felicity create an antidote for the Mirakuru drug.
In March 2014, it was revealed that Gustin would not appear in a third episode of Arrow as originally planned. However, Danielle Panabaker and Carlos Valdes appear in the Arrow episode "The Man Under the Hood" in their roles as Caitlin Snow and Cisco Ramon, respectively. Arrow executive producer Marc Guggenheim stated, "This was something that really came about because obviously Barry is in a coma at the end of "Three Ghosts". That pretty much made it impossible for Barry to appear in the third episode, as originally planned. The idea of bringing in Caitlin Snow and Cisco Ramon really, really appealed to us because it allowed us to honor our original intention of]doing something Flash-related around episode 19 or 20 of season two without having comatose Barry and basically paying Grant Gustin a lot of money to sit around with his eyes closed just unconscious the whole episode... It allows us to further flesh out the Flash universe in Arrow." In May 2014, it was revealed that Stephen Amell will appear as Oliver Queen / Arrow in the pilot episode.
Regarding Gustin's debut as Barry Allen in Arrow and the potential for a series, IGN's Jesse Schedeen stated his concern:
"Gustin doesn't come across as leading man material. His awkward bumbling intertwining with Felicity's was cute, but rarely did I get the impression that this character could or should be given his own spinoff series."
However, Schedeen eventually warmed up to the character, once the "dorkiness and social awkwardness" were downplayed a bit, and the emphasis was placed on "his keen scientific mind."
Summing it up:
The Flash is coming to CW this fall (Tuesdays, 8pm), and a first good look at the new superhero series has just premiered online in the form of an over five-minute-long trailer. The show appears to start as a fairly standard origin story, and while it definitely taps into some comic book clichés, it also appears to be willing to have a little fun — which is perhaps a good thing for an extended television series.
Though it won't be airing until fall, The Flash, as his alter ego Barry Allen, has already appeared briefly in CW's other DC Comics superhero series, Arrow. The Flash will be a casual spinoff in that sense, and from this new series' trailer, it looks like there will continue to be a big crossover between the two. It still appears to land far from the level of what Marvel's doing — and what DC certainly hopes to recreate — but it's still a start toward building a connected universe of its characters on TV.
