This isn't DCAU, nor is it strictly comic book business. I think this pretty much deserves its own topic, due to how massive this thing is.

For all those who aren't familiar with the comic, All-Star Superman is pretty much the best (IMO, and quite popular opinion) Superman story ever written, and one of the best comic books around. It mixes the uberman myth with tales of gods and massive undertakings, and gives us a look at the human being. It's an absolutely amazing work, and the fact that it's actually getting a movie, rather than another Loeb piece of crap, makes me very, very happy.
