As dour and moody as the DC films have been so far, it’s about time they throw some humor into the mix. A lot of the heroes who’ll be in Justice League haven’t been properly introduced to us yet, including Jason Momoa’s Aquaman and Ezra Miller’s Flash. It’s only Superman who will have had a solo introduction before Justice League kicks off, with Ben Affleck’s Batman getting his intro in the middle of essentially the second Superman movie. Luckily, Batman and the Flash will have some quality time to get to know one another, as, according to Ezra Miller, it sounds like the two will have a more buddy comedy-style relationship.

Speaking with IGN about Fantastic Beasts and Where to Find Them, Miller lit up when talking about his and Batman’s interactions.

I think it’s the relationship between someone who is naive and excited and someone who is experienced and jaded. And it’s that seeing each other as reflections of one another and being amused, and maybe sometimes annoyed, by one another.

It sounds like seeing these two onscreen together will be one of the more fun parts of Justice League, and Ezra Miller is clearly excited about having some fun with his character. Which is good for him, because his solo Flash movie is stalled until they find a new director.

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.

Justice League opens in theaters November 17, 2017.
