The production woes during the three 'Bourne' films are the stuff of moviemaking legend. Doug Liman butted heads with studio executives during 'The Bourne Identity,' and things didn't go that much smoother for 'The Bourne Supremacy' and director Paul Greengrass. Which is to say nothing of the mess that was the pre-production period during 'The Bourne Ultimatum,' the final installment in the franchise, to date, with Matt Damon. How bad did things get on 'Bourne 3'? Bad enough that Damon just told GQ in a new interview that writer Tony Gilroy's initial script draft was "unreadable."
