Bradley Cooper and Ryan Gosling have been suggested so much for so many roles that they're starting to become boring, not as actors, but as choices. I want to see some new faces. Choices that either make me go "Hmmm, Now that's interesting." or "YES! YES!" or "WTF?"
My choice for Flash would be Scott Porter. Dude needs to play a superhero.
Bingo!
Just what I can imagine Barry would be. Just some guy who looks harmless.
