The first official teaser for The Flash has been released online. You can see it below. The series, which will launch in the fall, was planed as a spinoff from Arrow, the popular DC Comics adaptation based on superheroic archer Oliver Queen, the Green Arrow. Barry Allen — The Flash — appeared in a pair of highly-publicized episodes around midseason and, at the end of the second episode, returned to his native Central City and fell victim to the accident that will ultimately give him super powers. The series will star Glee's Grant Gustin as Barry Allen/The Flash, a Central City CSI who works with S.T.A.R. Labs to help manage his powers. Cisco Ramon (Carlos Valdes) and Caitlin Snow (Danielle Panabaker) will be the S.T.A.R. scientists closest to him, and they have already appeared on Arrow as well (in the aforementioned Episode 20). Jesse L. Martin, Rick Cosnett, Candice Patton, Tom Cavanaugh, John Wesley Shipp, Michelle Harrison and Patrick Sabongui also star. The series will debut on The CW in the fall.
