Miller fills in EW.com that the costume for The Flash doesn't come out of a ring like in the comics, but says they still have plans for some cool stuff.
"Well, you know, look. I can confirm, spoiler alert, his suit does not pop out of his ring [in the movie],” Miller says. “Things have to progress, you know? Original Barry Allen was clearly an incredibly, incredibly clever scientist. We acknowledge and respect that. We want to apologize to the fans who are mad about the ring thing. I know the ring is the coolest thing about the DC universe. It was a little hard for us to sell in this version of this universe right now. Bear with us! There’s gonna be other cool things.”
Justice League has a November 17, 2017 release directed by Zack Snyder, with the story by Chris Terrio and Zack Snyder, the screenplay by Chris Terrio and Joss Whedon, and stars Ben Affleck as Batman, Henry Cavill as Superman, Gal Gadot as Wonder Woman, Jason Momoa as Aquaman, Ezra Miller as The Flash, Ray Fisher as Cyborg, J.K. Simmons as Commissioner Gordon and Willem Dafoe an Atlantean, Nuidis Vulko.
Fueled by his restored faith in humanity and inspired by Superman’s selfless act, Bruce Wayne enlists the help of his newfound ally, Diana Prince, to face an even greater enemy. Together, Batman and Wonder Woman work quickly to find and recruit a team of metahumans to stand against this newly awakened threat. But despite the formation of this unprecedented league of heroes—Batman, Wonder Woman, Aquaman, Cyborg and The Flash—it may already be too late to save the planet from an assault of catastrophic proportions.
