The article doesn't jibe with what Terry Rawlings has said. Rawlings (and others) have said that Fox shut everything down at Pinewood, put an assembly together to work out what more had to be done. Fincher and Rawlings said 'we need A, B, C,D, E, F and G' and Fox said 'You can do A, B, E and G' and this struggle went on and on for some time.
Valaquen has probably written stuff on this.
