How do I find out how much a screenwriter got paid for a project?

Question by Droga A: How do I find out how much a screenwriter got paid for a project?
I have read a few screenplays online and its pretty cool but is there an online source that lists how much a writer got paid? If there isn’t there is one movie I would like to know: If anyone knows how much Diablo Cody got paid for Juno I would greatly appreciate it. Please post source if possible. Thanks and I will be awarding a best answer.
