Speaking to EW, Miller was open and honest about the Flash's role on the Justice League team, as well as in his assessment of the Flash's teammates.
"Flash is Ringo Starr," says Miller. "He annoys everybody, but he doesn't have any specific beef with anyone."
As for the rest of the Justice League, he describes it as a family dynamic.
"Uncle Fish Curry [Aquaman] is very grumpy. Dad [Batman] gets grumpy too. (He's had a long life of fighting crime.) - Wonder Woman is very considerate, so even though she's annoyed with the Flash, she's still very compassionate."
In Justice League, 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.
Justice League is directed by Zack Snyder, from a screenplay by Chris Terrio, and features an ensemble cast that includes Ben Affleck, Henry Cavill, Gal Gadot, Ezra Miller, Jason Momoa, Ray Fisher, Ciarán Hinds, Amy Adams, Diane Lane, Jeremy Irons and Jesse Eisenberg.
