You can tell in the Darabont interview how crushed he was that it was canned. We may know none of the particulars, but man does Lucas sound like a pr**k after reading that. I really hope after IJ4 comes out, it's available to read.
What could possibly have been in it that Lucas was so objectionable about. Maybe some wicked dialogue like, " I hate sand, it gets everywhere!" or perhaps,"You're so beautiful." " No, it's only because I'm in love!" " No, it's because I'm sooo in love with you!".
Wasn't it Ford who said, "You can write this s**t George, you just can't speak it!"
