I'm fine if they go the New 52 route, but I don't want to see him in armor no matter what they do, and I don't want the little lines all over him looking distracting or HUGE either if they go the New 52 route, if anyone's seen the New 52 Flash skin in the Injustice game that is about ideal as far as what I'd like a live action New 52 style Flash suit to look like.
Big, heavy looking, treaded gold boots with wrinkles a little above the ankle line are a must, The Flash's colors must be a deep crimson and gold, not red and yellow; the red is deep crimson, and the yellow is gold/metallic looking and shiney. The earpieces are sharp and shiney looking and should look EXACTLY how Ethan Van Sciver draws them, they are not wings and don't have feathers (sorry, Alex Ross), I'd call them door handles before I caled them feathered wings).
Here is a perfect example of what I mean:
^^ That's
EXACTLY how the ear pieces should look. Period. They look cool there and they look great.
And take a look at this picture below to see what I mean about how the boots should look:
Epic, right? ^^
And finally, I just posted this because I think it would make a fantastic poster for the movie, on the area that Barry Allen is covered by the lightning bolt (but sub the "Z" lightning for Zoom (aka Professor Thawne/"Reverse Flash") out for the actual Flash logo of course, then you have a perfect poster
), he appears in his Flash uniform. Sums up the whole character pretty perfectly:
Material wise, the suit needs to be very different from a lot of things we have seen before; it must shine, but not look like Spider-Man spandex, but it also has to be "durable" looking like it's made from an actual "scientific" material if you know what I mean.
