Geoff Johns, who wrote the The Flash pilot for The CW, as well as produces the series, is also an executive producer on Batman v Superman: Dawn of Justice. Speaking at the TCA panel for the upcoming DC Comics series, he clarified the differences between the DC Cinematic Universe and its small screen companion, confirming that the two streams will never cross. This also means that we'll never even see small screen versions of Batman or Superman on either The CW series Arrow or The Flash.
The comic book writer explained that there has never been a plan to incorporate the two different universes into one entity, and that the small screen actors who portray Arrow and The Flash, Stephen Amell and Grant Gustin, won't be squeezing their way into Justice League either.
""You'll see a lot of DC universe characters [on The The Flash and Arrow]. You won't see Batman or Superman. We're on production on Batman v Superman now. So you'll see characters like The Atom or Firestorm, but no not Batman or Superman right now [on TV].
It's a separate universe than film so that the filmmakers can tell the story that's best for film. While we explore something different in a different corner of the DC universe. We will not be integrating the film and television universes."
While Superman and Batman will not be showing up on The CW anytime soon, another character from Dawn of Justice might still get her own small screen series. A new Wonder Woman hour long drama has been attempted many times, but just hasn't been able to land a show since 1976's cult favorite went off the air nearly 40 years ago. The CW even tried to resurrect the iconic superhero in Amazon, which would have focused on a young Diana Prince. That iteration of the story failed to get off the ground. But the network isn't giving up hope. The CW's Mark Pedowitz teases that DC Comics and Warner Bros. might figure out a way to bring Wonder Woman to TV sometime in the near future.
"If she is and we can get the right script we will do it. One of the nice things is that a lot of the other broadcasters and cable networks have done Comic Book Characters based on the success of Arrow. So for our purposes, it is a rich source material, we know what the mythology is, and if you have the right superhero character you go for it."
