Barry Allen and Hal Jordan bromance

This is awesome.
These two are PERFECT for Barry Allen and Hal Jordan! I can definitely see Cooper working as Hal.
And everyone - ya'll know Ryan Gosling is my number one pick for The Flash/Barry Allen, and the fan favorite as well. He is a terrific actor and I have wanted him for this role since I watched him in Fracture (where he even does some forensics/detective work to convict Anthony Hopkins' character of brutally murdering his wife, even sports a bow tie in some scenes,
and Zoe Kazan who was cast as Iris West in the Justice League Mortal film from '09 plays a coworker of his! There's some trivia for you

). (Gosling also gives a good performance in Lars and the Real Girl, for anyone who wants to check it out)
The guys working on the current Flash comic book in the New 52 both see Ryan Gosling as The Flash. I know this because I am personally friends with Brian Buccellato, who writes The Flash, on facebook, and have asked him myself who he would cast as Barry Allen/The Flash for the live action Flash movie. We've talked about it at least twice.
I just hope he's on WB's radar for the part because he could really do the role justice. I think with the right talent involved he would get behind it, at least just for Justice League since he enjoys playing "supporting" characters. I really think he'd do well as a leading man with The Flash feature though too.
Gosling is a good actor and has the right amount of box office clout for the part. With the right team behind it and if it does well I can see it making him a superstar, even though I can't seem to go a day without seeing his name mentioned somewhere as it is - sure, there are other people who would probably do well in the role, but Ryan Gosling is at the very very top of that list for me, hands down.
