I think both Wonder Woman and The Flash are going to be at least 4 or 5 years till they get to the cinema screens if they ever do make it!
I dont know if anyone else has mentioned this but David Goyer new DC film is this one:
""Super Max" is Goyer's take on supervillain incarceration in the DC Universe. Revolving around a wrongly convicted Green Arrow being whisked away to the super max prison for out-of-control heroes and villains, the man is forced to face a number of inmates he put there.
Goyer likens the film to "Alcatraz" - "He has to team up with, in some cases, some of the very same villains he is responsible for incarcerating in order to get out and clear his name. Of course, tons of people try to kill him while he's in there. We've populated the prison with all sorts of B and C villains from the DC Universe... but they're all going to be there under their human names and no one is wearing a costume, but there will be a lot of characters with powers and things like that."
Goyer, developing the project with writer Justin Marx, says the Green Arrow will only make a small appearance in costume - "He's Green Arrow for the first 10 minutes of the movie, and then he's arrested and his secret identity is revealed".
