In the house in Munich, when Jason Bourne uses the rolled newspaper as a weapon, the martial art he performs is derived from Escrima, an old Philippine martial art, also called Arnis or Kali. This fighting style mainly uses sticks to fight, and in modern times the use of objects from our everyday life is taught, including ball pens (as seen in The Bourne Identity (2002)) and rolled up newspapers.
Virtually all of the events in the movie were shot in the reverse order of location. This means scenes in Moscow were shot first and those in Goa were shot last
The film originally ended with the confession to Neski's daughter. Following previews, which found the ending too bleak, the New York postscript scene with Bourne and Landy was shot, just weeks before the film's release in the summer of 2004.
The first scene shot was the scene in Moscow where Bourne speaks to a taxi driver and arranges to pay in Dollars.
The phone that Jason Bourne uses is a Siemens ME45.
Unlike the James Bond franchise, all the devices that Bourne uses are real and can be purchased by the average citizen.
The 14 November 2003 draft of the screenplay credits Brian Helgeland for a rewrite. He is not credited in the final film.
When Bourne calls Pamela Landy from the rooftop, a voice is heard in her office saying that they "need 90 seconds to triangulate his position". Bourne disconnects the call exactly 88 seconds later.
The taxi that Bourne drives during the car chase is a Russian-made Volga 3110.
