Filmmaker Kevin Smith says that higher-ups in charge of adapting DC Comics characters for the screen have left the door open for a potential crossover between the shared cinematic universe and the shared television one, eventually.

Smith hosted this week's "DC Films Presents: Dawn of the Justice League" television special, where a ton of new footage for upcoming DC movies -- including a new "Suicide Squad" trailer -- was unveiled. But one segment that Smith recorded with DC Comics Chief Creative Officer Geoff Johns was cut from the special, and it is one that should be of particular interest to "Flash" fans.

Grant Gustin has won acclaim for his portrayal of the Flash on the self-titled CW television show, set in the so-called "Arrowverse" of shared DC stories, but some were disappointed when Warner Bros tapped Ezra Miller to play the character in the big-screen adventures. Smith was among those who believed Gustin would have made a worthy big-screen Justice Leaguer, and while discussing his experience hosting the special on his "Fat Man on Batman" podcast, he mentioned an exchange he had with Johns that left him believing that Grant Gustin's Flash and Ezra Miller's might be racing on a collision course.

"We did a piece where we talked about -- I don't know how much I'm supposed to say because they cut it out," Smith said on the podcast. "But the idea [came up] of, 'Hey man, DC is known for nothing if not a multiverse,' so at which point I was like [to Johns], 'Could they fucking crossover?' And he was like, 'Ahh.' So doors are being left open and stuff like that."

While it's no official confirmation, Smith's recollection of Johns's response indicates that, at the very least, a TV/movie DC crossover is under some level of consideration. As Smith explained, "Think about this, you can have Ezra Miller be the Flash and you could also have Grant be the Flash, because there's a multiverse at work."

It would have to be a way's down the horizon, with the "Justice League" movie not due in theaters until November 2017, but between the TV shows, and now this March's "Batman v Superman: Dawn of Justice" promising to unite many heroes of its own, DC is becoming as known for team-ups as it historically has been known for multiverses and crises. So maybe a Miller/Gustin race is a way's in the future, but when you're talking about the Flash, the future always comes faster than you might think.
