Grant Gustin'a appearance as Barry Allen in Arrow seems to have gone down pretty well with most fans, but can he carry his own series? We'll find out in the Fall. In the meantime we await some set snaps of that full Flash costume. The Flash also stars Tom Cavanagh, Jesse L. Martin, Candice Patton, Danielle Panabaker, Rick Cosnett, and John Wesley Shipp. The show is directed by David Nutter with a script from Geoff Johns.
