The teaser for The CW’s new Fall 2014 series The Flash aired during the season finale of Arrow, and almost immediately people were talking about it online. The teaser, which showcased Green Arrow and Flash, featured Grant Gustin as Barry Allen, the Flash, the first time he’s shown up since November’s two-episode appearance.

TV’s original Flash, John Wesley Shipp, is also part of the cast, which includes Daneille Panabaker, Carlos Valdes, Tom Cavanagh, Jesse L. Martin, Candice Patton and Rick Cosnett.

Arrow’s Greg Berlanti, Andrew Kreisberg and David Nutter will serve as the new show’s executive producers, with Nutter directing the pilot written by Berlanti, Kreisberg and DC Entertainment’s Geoff Johns.
