From what we learned before and during production of the Depp/DS film, supposedly the story in August's script is the same. The difference is that Grahame-Smith punched up the humor, much of which was already there. But I definitely agree that it would be interesting to see how different/how similar both scripts are to each other. And part of me is actually surprised that both haven't shown up on the Internet. At least not that we know of...
