The CW's proposed 'Arrow' spinoff 'The Flash' has certainly come a long way with its casting process, though we won't know just yet if the network decides to follow through on a series order, or stop the project in its tracks. For as strong a track record as the network has win spinoffs however, what would become of Grant Gustin's Barry Allen if 'The Flash' ended up dead on arrival?

According to executive producer Greg Berlanti's latest interview with Digital Spy (h/t Blastr) a backup plan for Barry remains in place, likely involving Gustin returning to 'Arrow' for a more continued presence. "Fingers crossed we don't screw it up and he gets his own show!" says the producer. "If he didn't, I don't think we would ever want to let Grant go. He's too valuable. That would be our hope, I think - no matter what, to keep Barry part of the universe."

We might not necessarily expect that Gustin would join 'Arrow' as a regular, given how the Flash and his powers could easily steal focus from Stephen Amell's brooding Oliver Queen, though at the very least, we'd likely see Barry a few times over the course of a season.

Elsewhere, 'The Flash' has cast in known roles Candice Batton as Iris West, daughter to Jesse L. Martin's Detective West, along with Carlos Valdes as Cisco Ramon, better known as DC character Vibe. ‘The Vampire Diaries‘ star Rick Cosnett will portray Central City Police transfer Detective Eddie Thawne, who most likely corresponds to ‘Flash’ comic villain and time-traveler Eobard Thawne, better known as “Professor Zoom” or “Reverse Flash.” Danielle Panabaker will play Caitlin Snow, a highly intelligent bioengineering expert who lost her fiancé during an explosion at S.T.A.R. Labs and is an incarnation of DC villain Killer Frost.

For the moment, little else is known of The CW’s ‘Flash’ spinoff, though it was decided the character would be given his own pilot rather than return for the 20th installment of ‘Arrow”s second season as originally intended.

Well, what do you think? Should 'Arrow' welcome Barry Allen back if 'The Flash' doesn't make it to a full series on The CW? How would you like to see the spinoff handled going forward?
