In the Tangier chase scene Nicky and Desh are seen pushing past the citizens. These are not extras; Tangier was too crowded and the flow of the people was hard to control, hence the two actors are genuinely pushing through the crowd.
Since the opening scene of the film takes place directly after the ending of The Bourne Supremacy (2004), but the production gap was several months, it was now January in Moscow. This would have been too cold and so Berlin was chosen as the location of the shoot, with a Moscow set being created. The fake snow was made using paper and foam, and took an excess of 5 hours to cover the entire set. Paper and foam were used instead of real snow so there was no risk of melting.
When they were shooting in Tangiers, it was in the middle of the Muslim fasting month of Ramadan, where no Muslim can eat or drink during the daylight hours. Interviews in the bonus material reveal that several of the crew members were Muslims, and found it exhausting to do the movie while being unable to eat or drink. Matt Damon comments on how he would see them look 'longingly at a cup of coffee or a sandwich'. To accommodate these crew members, the remaining members of the crew tried to discreetly eat and drink.
As in the previous films, the type of martial arts used by Jason Bourne is a combination of Filpino Kali with Bruce Lee's Jeet Kune Do. The character of Desh uses the same combination, as well as some moves from the Brazilian martial art of Capoeira.
Voted as Movie of the Year 2007 by Empire magazine. It is Paul Greengrass's second work in a consecutive year to be voted Movie of the Year by Empire. His previous film, United 93 (2006) was voted as Movie of the Year 2006.
While filming in Tangiers, the crew had to close down the busiest square in the city for several hours while shooting. In the bonus material, you can see a crowd of slightly irritated looking locals who had no warning that the closure would take place.
As shown to Pam Landy on a computer screen Jason Bourne enters New York as Gilberto de Piento from Brazil. The identity's passport is briefly shown in The Bourne Identity (2002) during Jason's exploration of the deposit box in Zürich. But the spelling there is Gilberto do Piento. Furthermore: in _The Bourne Identity (2002)_ this name appears not as one of Bourne's alternate names, but as the name of the Brazilian consul who signed the passport. In that old Brazilian passport, in the 2002 film, Bourne's name appears on another page entirely and is actually listed as João do Carmo.
The end title music for The Bourne Identity (2002) and The Bourne Supremacy (2004) uses the exact same recording of "Extreme Ways" by Moby. This film uses a new performance of the same song, with a distinctly different mix, called "Extreme Ways (Bourne's Ultimatum)".
In the CIA substation where a operative intercepts Simon Ross's call using Echelon the numbers given on the screen are various locations in the UK. One number is 020 7946 0621 and various others. These are in fact "fake" numbers used by TV and Theatre companies to add more realistic drama to films unlike the "555" system used in the US. Also on the screen is the dialing code for Reading, and the 01632 which is fictional (US 555 equivalent)
Bourne's arsenal (in order) consists of a Dual Tone SIG Pro SP2022 he used in the bathroom at the beginning of the movie, a Black SIG Pro he took off of the CIA Agents in the Madrid Office, a Beretta 92FS he took off a Tangiers police officer, a Black Glock 17 he procured mysteriously in the parking lot near the CIA building in NYC, which in turn ended in another mystery as he procured another SIG Pro during his questioning of Dr. Albert Hirsch.
When the CIA hacks into Simon Ross' Guardian e-mail, finding a round-trip ticket to Turin, the e-mail is presented as being sent from firstname.lastname@example.org - Adrian Spanna worked as a second unit video assist operator on the film.
A copy of former United States President Bill Clinton's autobiography, "My Life," is visible on a shelf in Vosen's office. A copy of Nelson Mandela's autobiography, "Long Walk to Freedom," is visible above Clinton's.
The production devoted six weeks to filming the climactic car chase in lower Manhattan. In the sequence all vehicles are being operated at no more than thirty-five miles per hour (35 M.P.H.) because the New York Police Department would not allow greater speed due to concern for public safety.
Operation Blackbriar, the focal point of the film, was introduced in The Bourne Identity (2002). Near the end of that film, Abbott is before a U.S. Congressional review board and explains Treadstone was a failure; then he closes a file and discusses Operation Blackbriar.
