Belated reaction to the casting of Astoria Greengrass

So I don't really follow any news about the movies AT ALL, just kind of figured anything big enough might make it to my flist one way or another, but that's the problem with being interested in things that very few people on the flist are interested in.

Like Astoria Greengrass. Who has apparently been cast as early as... what, June of last year?
