Shooting starts on September 30 for the first Flash guest spot on “Arrow,” and the studio is casting Barry Allen now. Latino Review reports that the field has been narrowed down to three possible actors:
I’m not familiar with any of them myself, and while Barr’s publicity shot looks more like the Barry Allen we know from the comics than either of the others, it’s worth noting that actual TV and movie series often aim more for the acting style or personality wanted than physical resemblance to a character design. (Case in point: John Wesley Shipp as Barry in the 1990s show. Or the entire cast of The Middleman, which turned out perfectly IMO.)
