Grant Gustin is the new Barry Allen - aka The Flash - set to appear in three episodes of Arrow Season 2 before getting his own spinoff series.
The 23-year-old actor is known for Glee and 90210 and will appear in episodes 8, 9 and 20 of Arrow.
Barry Allen is described as an assistant forensics scientist working for the Central City police department, where a string of unexplained robberies may have a connection to a tragedy in his past. It's also said Barry Allen is a comic book fan boy who is obsessed with the Arrow and is unaware that working with Oliver Queen and Felicity to solve the crime has brought him right into the dangerous world of the vigilante.
Greg Berlanti, Andrew Kreisberg and Geoff Johns will executive-produce the Flash spin-off, with David Nutter directing the pilot (Nutter also directed the pilot episodes for Arrow and Smallville) and episode 20.
Stephen Amell, who plays the lead with Oliver Queen/Arrow, congratulated Grant Gustin on Twitter.

The Flash Arrow episode begins filming at the end of September. Previously, Greg Berlanti offered that The Flash will have powers and the red suit.
"That said, he does need powers to become The Flash. And he will be The Flash. He will wear a red costume, and he will go by that name."
Arrow Season 2 returns Wednesday, October 9th at 8pm ET on the CW; it's thought The Flash episode will air in December.
