Both those "choices" look like "women" to me. Don't know what you're used to, but I see women.
STAR TREK academy? How clever. Next someone will come up with NEW JEDI ORDER or whatever it's called. Or perhaps go for the scathing bit of HARRY POTTER wit. Or (gasp) YOUNG JUSTICE.
People seem to forget: The JLA was younger once upon a time. Yes, the core members had established careers when they formed the league. But remember, The Batman was "established" by age 26 in DC continuity. (His YEAR TWO) Superman was around at 25 or 26, last I knew. And Diana was ALWAYS portrayed as young )close to teenager status) when she started out.
My point is, they weren't in their mid thirties going by comics continuity when the JLA began. They were 25-28ish. Pick up and read some JLA: YEAR ONE issues. And half the YEAR ONE annuals, and anything that shows "classic JLA" stories. The characters tend to be portrayed fairly young.
Re: Wonder Woman looking like a "woman", fine, but where I come from a girl is considered a woman because of her poise and actions, not how many lines she has. I have yet to see a version of Wonder Woman in the comics (aside from Alex Ross's) who doesn't at least look fairly young. If she's going to be young in the movie it makes even MORE sense.
And frankly, all this panicking over what so far have proven to be nothing but rumors is sad. You all act like WB, because they auditioned several popular actors for what may end up being the biggest superhero franchise in history, has decided to cast teenagers as the JLA. Which is simply not the case.
There's a difference between auditions and actual casting announcements.
