Ezra Miller's Flash Is Already Being Called The Best Part Of 'Justice League'

New details emerge from the set of Zack Snyder's <i>Justice League</i> — and they're promising

Zack Snyder has a secret weapon, and his name is Ezra Miller.

Last week, a group of journalists were invited to the sprawling London set of Justice League. Yes, it was a strategic PR move from Warner Bros., which certainly wants to combat any negative misconceptions in the wake of Batman v. Superman: Dawn of Justice. But it worked; based on reports, Justice League seems like a much-needed lighter counterpart to Dawn of Justice -- and we have one man to thank: Miller's Barry Allen.

Miller is talented for sure. But most importantly, he's funny -- oddly charming, even! (Very oddly charming.) Barry Allen is one of DC Comics' most optimistic, hardworking heroes. He's a bit quirkier than most, and from what we've read, Miller plays him to perfection, adding some sorely needed comic relief to the JL dynamic.

"There's a quality to what Ezra does that is young and fun and full of life, that's excited about what they're doing, that's so in contrast to who Batman is," Ben Affleck told Vulture and a group of reporters on set. "What does Batman do around a guy who’s really excited and positive all the time? It's not his natural state of being."

During the visit, reporters also saw a rough cut of a scene between Batman and The Flash that demonstrates the film's lighter tone. (It involves a batarang, some slow-mo, and some funny ad-libbing from Miller.)

Initially, not every fan was keen on the casting of Miller as the scarlet speedster, especially with charmer Grant Gustin lighting up the silver screen as the Flash on The CW. For some fans, the argument was that Miller simply didn't look the part of Barry Allen — that he was far too scraggly to play the Justice Leaguer. However, that was before Miller debuted his buff new superhero body and got his shiny new Flash suit.

Uproxx describes the speedster's new crimson suit as "a sleek Iron Man suit, with individual crimson red metallic parts (148 of them, to be accurate) form-fitting to the body. From the side, the top of the cowl kind of looks like a bicycle helmet." Barry's new duds also feature electrical coils to trap the electricity he produces through the Speed Force. Of course, this might be Barry's own prototype, so there's no telling what kind of upgrades Bruce Wayne will make in the future.

Either way, we'll have to wait until November 2017 to see the speedster's interesting new look for ourselves. But one thing is abundantly clear: Snyder heard your complaints, and he's trying.
