... to spite ones' face?

I don't understand how the studio can be so against an audit of a projects' accounts that it would basically throw away and almost 100% guaranteed successful end to a brilliantly popular franchise.

If Jackson wants to re-negotiate on a done deal? Then state it that way. As it is though... Bob Shaye is coming off as a petulant spoiled executive who has been caught with his hand in the cookie jar. He may be totally justified in his ire but he needs to get a good publicist before he destroys any goodwill the fans may have left after the disappointment of missing a peter jackson replay.
