Andy Muschietti sur le ton de l'histoire :
"My Flash is not gonna be light or dark in tone. It's gonna have everything. If you saw my previous movies like It and It 2, you'll know that I like to put everything in it. So what you'll see in Flash is very deep emotional story, but it's also gonna be very funny hopefully and a great, epic adventure at the same time. And also terrifying sometimes. So that's my answer. Get ready."
Ezra Miller sur le costume :
"I have yet to see it. But I've heard some things about it and they're extremely exciting. There'll be some twists- in some ways, I believe it will be a more traditional, comic-based costume but in other ways, it might be somewhat unconventional. I've heard it might be lighter than my last suit as an example of some of the changes. I'm not sure how much I can say."
