 SPOILERS: Before Brian Helgeland did his rewrite, Tony Gilroys  initial draft of the screenplay was vastly different. Instead of  Kirill shooting her, Marie dies by accident when a bus veers off the  road and slams into her. Bourne is outraged and goes berserk on the  driver, almost killing him until the police arrest him. A large  section of the film is then spent in an Indian prison, where Bourne  makes numerous allies and enemies before planning his escape. From  then on in, both scripts follow a similar track.
