Neil Purvis and Robert Wade are writing the script with Peter Morgan. The latter is not - as Paul Haggis was not - some mythical "script doctor" who comes in and cleans up the project at the end. And as the film will not emerge for a while, that seems plenty of time to iron out and chisle the script into something all are happy with.
Well, dear Zorin, I hope you´re right. But a director will try to put his stamp on the material. Maybe EON will choose a more workman-like director this time or they will control him more so that the script does not have to be re-written totally.
As to the process of collaboration, I understand that Haggis indeed was not "just" a script doctor but he was the second writer on CR and QOS (counting Purvis/Wade as one, since they do write together). Morgan seems to do just that as well - going in after Purvis/Wade have written a first draft. Or do you have intel that says otherwise?
