Okay. I'm pretty sure I'm caught up with all the interviews and info on the web. From what I've been able to gather, nothing about the authorship of the screenplay has been conclusive, other than the fact that it's officially credited to Goyer.
I remember someone's post on IMDb mentioned that Snyder added a third fight scene, but that rumor (along with everything else in the post) was apparently discredited as fan-fiction by a WB source.
