We've also recently learned, thanks to a source who has inside information on the movie, that the filmmakers behind The Flash have a quite specific look in mind as they design the superhero's outfit.

Understandably, they're seeking to avoid "any comparison to the well designed and received TV version," we're told. To ring the changes, they're aiming to create a more "tech-based" suit that will look quite different from the burgundy leather outfit designed by Colleen Atwood for the series. Instead, this one will look more "like armor."

When it comes to The Flash's movie costume, a comparison has been made to the version of the hero seen in the videogame Injustice: Gods Among Us. Take a look at the images below, and you can immediately see the differences between the clean, classic-looking TV show costume (on the left), and the spiky, more aggressive one presented in the videogame (on the right):


The design choice seems to fit with the rest of the DCU we've seen so far; Superman's costume in Man Of Steel was all muted tones and tough, kevlar-like texture. In Batman v Superman, meanwhile, we'll be seeing the Caped Crusader wear both a classic cloth outfit and a heavily-armoured Batsuit -- all the better for taking on the Son of Jor-El. Even the Wonder Woman costume we've seen so far has a weighty, armor-like feel to it -- though this may not be the only outfit the warrior princess will wear through the course of the movie.

According to our source, Ezra Miller's Barry Allen is now something of a "tech geek," which also seems logical given his day-job -- that of a forensic scientist.

Tom Cavanagh Wishes Snyder Considered Grant Gustin for DC Films' "Flash"

The Harrison Wells actor told the site, "It was either Variety or Vanity Fair that wrote an article that said [DC] needs to watch what they’re doing on TV, because the TV’s working and some of the other darker stuff isn’t working. Here’s what I’ll say about him not being The Flash. The first thing is that for Zack Snyder to say 'that’s not really the universe that we’re building,' it’s excruciating for an actor. Because you’re like, 'Uh, what about acting?' He’s a clean-cut guy and winning, yes, because he’s acting that. He’s not Barry Allen. He’s Grant Gustin. He created that thing. If you want [your Flash] to have long hair and be a slacker, believe me, Grant can play that."

Cavanagh continued, "[Gustin] makes it look easy and makes everyone think that’s what he is because he’s an incredibly skilled talent. That’s why he has that job. That’s why people like the show. If Zack Snyder were to read him for [The Flash], he would be shocked. It’s crazy for a big-time Hollywood director to say 'that’s not the universe.' It’s a huge misstep on his part. If you’re a director, and you’re worth your oats, then you should be able to, given an actor with talent, mold him into what you want, and Grant could do that."
