The CW's TV version of The Flash has become a crossover hit, but while the TV series and its hero have become iconic, there's competition looming on the horizon, as the Justice League movie will introduce actor Ezra Miller as the DC Films' version of The Flash, with all the blockbuster movie budget and special effects that go along with it.

So far, DC Comics fans have been generally pleased with the look of Miller's Flash movie costume, which has once again prompted discussion about the look of TV Flash (actor Grant Gustin), and whether or not his iconic scarlet costume is really up to snuff.

Comicbook.com had a chance to speak with The Flash cast (including Gustin) at San Diego Comic-Con 2017, and it turns out that the actor who has to wear the costume of the Scarlet Speedster is one of the most adamant about that costume looking good!
