4. Ryan Gosling As The Flash
This guy has been my pick for the Flash ever since I saw him in Drive. I can actually imagine Gosling in the Flash costume and it just fits perfectly. He is an incredible actor and would be a good name for Warner Bros to get ahold of given how much his star in is the ascendancy. That might involve convincing Gosling to turn his back on his decision to take a break from acting, but there may well be a good few years before JLA even starts filming. Now obviously the Flash is a hard character to make interesting to non comic book readers due to him really just being a guy who can run fast, but he is still long overdue a movie treatment and comic book fans would love to see him on screen. Not only that he is an integral cog in the JLA machine. Gosling has already apparently expressed an interest, and hinted at a team up with Nicholas Winding-Refn, which would offer an intriguing look at the comic book property. If Gosling is not Flash however, I would be fine with Bradley Cooper, him being Oscar nominated and all.
