As glimpsed in the San Diego Comic-Con teaser for next year's Justice League, the relationship between Ben Affleck's grim Dark Knight and Ezra Miller's eager Flash might not be what audiences expect of two superheroes working together to save the world - in fact, according to Miller, it might be better suited to a buddy comedy.
"I think it's the relationship between someone who is naive and excited and someone who is experienced and jaded," Miller explained in an interview with IGN. "And it's that seeing each other as reflections of one another and being amused, and maybe sometimes annoyed, by one another."
He went on, "I think Bruce and Barry get a kick out of each other because they're seeing themselves but reflected in this very warped mirror, you know? Bruce, the aged Batman, is everything that being a superhero means you could become, in terms of being, like, pretty shut down and having seen all this horror. He's like a veteran of this struggle against evil. And Barry is just getting into it, and it seems exciting! And very fun! And so, I think they have a lot to learn from each other, like in any great friendship. I think it's a fascinating relationship."
All the more fascinating when you consider that moment from Batman v. Superman: Dawn of Justice, which suggests that the Flash and Batman end up the best of friends - why else would Barry choose to travel back in time to warn Bruce of impending apocalypse?
