Writer-producer Greg Berlanti has now chimed in on this notion, confirming that there are no current plans to bring Arrow's Oliver Queen or Barry Allen to the big screen in Justice League or Batman Vs. Superman.
He doesn't exactly explain why, and he also doesn't rule it out in the long run. But it doesn't sound like this is happening anytime soon, if at all.
"We haven't had any of those conversations other than to say, what characters are we allowed to use this year and advocate or request certain ones that are of interest to us. And every now and then, they'll say, 'You can't have that guy.' They don't say why, and we figure out why later on."
When directly asked if the small screen and big screen franchises will ever come together, Greg Berlanti quickly changed the subject.
"Getting to participate in any way in the story - considering how much they meant to me as a kid - is really, I just feel lucky about that all the time. And it evolves the way it's supposed to...When it comes out naturally, that's when it's best. And that's been the fate of Arrow, and I guess that's the path we'll follow."
What do the fans have to say about this? Do you want a crossover? Or are the TV versions of these character too low rent for the big screen?
Batman v Superman: Dawn of Justice comes to theaters March 25th, 2016 and stars Henry Cavill, Ben Affleck, Amy Adams, Diane Lane, Laurence Fishburne, Gal Gadot, Jesse Eisenberg, Jeremy Irons. The film is directed by Zack Snyder.
