I suppose when you are the fastest man alive nothing can weigh you down because, according to a new rumor, The Flash suit Ezra Miller may be wearing in the movie is described as similar to armor.
According to Den Of Geek, a source filled them in that the movie studio is trying to avoid "any comparison to the well designed and received TV version," and that they are aiming to create a more "tech-based" suit that is said to look quite different than the Grant Gustin Flash costume.
It's said the Ezra Miller Flash costume will look more "like armor" with comparisons to The Flash from the Injustice: Gods Among Us video game (see above).
Ezra Miller's Barry Allen is also described as a "tech geek."
Speaking of Miller he has some rather large shoes to fill as Gustin's Flash is pretty popular. Interestingly enough, we do already have seen alternate versions of characters on the TV series, and Miller even stated they exist in parallel universes, so hopefully both can work at the same time (though separate).
Ezra Miller debuts in Batman Vs. Superman next March followed by Justice League and The Flash standalone movie in 2019 directed by Seth Grahame-Smith with a script by Grahame-Smith based on the story from Phil Lord and Chris Miller.
