Gustin is set to appear in three episodes of “Arrow” — eight, nine and 20 of season two. Episode 20 will also serve as a backdoor pilot for a spinoff focused on The Flash. If all goes well, the spinoff will be an origin story, not unlike that of “Arrow.”
“When we first meet Barry Allen, he’s just a forensic scientist … an ordinary man,” Andrew Kreisberg, co-creator of the show, said.
Gustin’s character will be a vigilante, whose on-screen story will be as realistic as possible. During his first two appearances, he will find himself in Starling City. In the third appearance, he will be seen in his own world.
Barry Allen is being described as an assistant forensic investigator who comes to Starling City to investigate a slew of unsolved robberies, which he believes may be connected to his past. As a lover of comic books, Barry is actually obsessed with the Arrow and is completely unaware that he has entered his world.
“Part of the fun for the audience … is to see how we view our ‘Arrow’ take on the Flash legacy,” Kreisberg said. “Some of it will feel very familiar to DC Comics, some of it hopefully will feel different, fresh and exciting. The same way we approached ‘Arrow’ is the same way we’re approaching Barry.”
Gustin, who is a comic book fan himself, added that he is excited about transforming into The Flash.
“I’m unbelievably excited. I’ve been a lifelong fan of DC Comics, so I can’t be more honored and can’t wait to get started,” he said.
“Arrow” returns to The CW on October 9.
