Jones departed for that vague and all-encompassing reason "creative differences." Variety reports that he had issues with John Romano's script, and neither Jones nor Lakeshore Entertainment were willing to budge. The studio is currently on the hunt for a new director, and hopes to be shooting by spring.
So, feel free to speculate on just what script issues there might have been. I know we have some Connelly fans who were looking forward to this, and who know more about the book than I do. Given that it is a star vehicle for McConaughey, and the character is a bit of a legal freewheeler, I wonder if the script is more of a comedic departure from the book. We've cracked a lot of jokes about bongo drums and shirtlessness, but could that actually have been what Jones departed over? It's sleazy and easy to jump to that conclusion, and I can't really believe a Connelly book could be adapted into Fool's Gold. But this is Hollywood. Stranger things have happened.
