It seems the grim and gritty days of "Batman v Superman" will be over by the time "Justice League" rolls around. One of the key aspects of the film that exemplifies the franchise's tonal shift is the relationship between Batman (Ben Affleck) and The Flash (Ezra Miller), which is unlike any other dynamic explored in a DC Comics-based film -- except, maybe, the original dynamic duo, Batman and Robin.
At the "Justice League" set visit in London attended by CBR News, among other members of the press, Affleck addressed a reporter's question about the Flash being a Robin-like character to Batman in the film:
That's interesting. There's an element of that to it. There's a quality to really what Ezra [Miller] does that is young and fun and full of life, and excited about what they're doing that's so in contrast to who Batman is. There's a little bit of that natural yin and yang to playing scenes with him. There's not the ward aspect to it, but there's a little bit of the mentor -- which you'd probably ask Ezra and he'd be like, "Fuck that! He's not my mentor!" But I think there is a little bit. And it's fun to play, definitely."
A scene was shown at the junket in which Bruce Wayne recruits the young Barry Allen. Played comedically, the moment could be compared to Tony Stark's recruitment of Peter Parker in "Captain America: Civil War." You can read a version of the scene over at Vulture.
Directed by Zack Snyder and starring Ben Affleck, Henry Cavill, Gal Gadot, Ezra Miller, Jason Momoa, Ray Fisher, Amy Adams, Jeremy Irons, J. K. Simmons and Amber Heard, "Justice League" is scheduled for release on Nov. 17, 2017.
