That would only happen if it somehow becomes a huge hit...they could weather the storm then because the media will become complicit in making Ezra a reformed actor with blockbuster appeal. It would need to be a huge breakout though...something that isn't possible even if the film is good.
We don't need official confirmation, we are both saying the same thing.
I am just not going to take anything from a clickbait site as gospel because there is no chance they know more than actual insiders do. They aren't wrong, they are just saying what we are saying so they get no credit from me
The Flash will recast post release, and no one will even really care because Ezra is just not that important. If a great actor like Ed Norton can be replaced and not have the franchises miss a beat Ezra friggin Miller can be too. (and again I like Ezra as an actor)
