Since Ezra might be done with the project, how would you feel if they added a Barry that was a few years older? Maybe one who has dyed his hair blonde, and is a bit more like our Barry? I wouldn’t mind, especially since the Flash movie isn’t coming for a while. I think it would be cool if he grew up a bit. We might not get another Flash movie until 2022, which is 5 years after JL. So it could make sense to switch to a different actor. If they looked similar enough, it could work. but who would you want to be an older Flash?
