Recently, "The Flash" released behind-the-scenes footage of the movie, and sharp-eyed fans found that in the scene of Batman, The Flash, and Wonder Woman in the same frame, Ezra Miller's buttocks playing The Flash are obviously different from those in the movie.
Comparing the movie with behind-the-scenes footage, we can find that the Flash buttocks in the movie are obviously more rounded and full than the actual shooting, and many people have ridiculed the Flash's new uniform for outlining Ezra Miller's ass too upturned, but now it seems that the real Ezra Miller is obviously not up to par.
In fact, Miller's figure has always been criticized by fans, compared to Henry Gadot's almost model-like sculptural body, Miller's figure is more thin, and when "Justice League" was filmed, in order to cover Miller's not wide shoulders, the film designed an armor-like uniform for him.
In "The Flash", because the uniform became a tights again, Miller's flaws in his figure were completely exposed, even if Miller did have muscles on his body, but he could not support the shoulders and hips of the uniform, so when Miller's Flash was first exposed, it was ridiculed by fans.
However, I think that these deficiencies can be made up for with CGI in the later stage, Miller's most outstanding is his acting skills, and it seems quite appropriate to use flaws as a whole.
