Just an FYI to everybody: I read draft #1 of Juno, and it was virtually identical to what made it on the screen. There were one or two added scenes, a few deleted lines of dialogue, and a few minor changes, but in terms of the meat of the script, it was pretty much exactly what you saw on screen.

To assume that all she "ever wrote" was "nonfiction" is to assume that everything everybody writes gets published.

There's some sexism and snobbery inherent in your assumption too. Isn't it kind of douchey to assume that only The Man, Jason Reitman could save The Girl, Diablo Cody, from crappy script-i-tude? And who the hell says that just because somebody started out as a blogger means they are actually incapable of writing something entirely other than a blog entry? Are blogs so low-class that there isn't the remotest possibility that they translate?

If you're as insider-y as you say you are, why don't you ask her manager to show you a copy of her first draft. You can compare and contrast for yourself. 'K?
