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 email@example.com - Adrian Spanna worked as a second unit video assist operator on the film.
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.
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.
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.
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.
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)".
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.
In all three Bourne films there is only one explosion scene. In The Bourne Identity (2002), Bourne blows up a gas tank to distract The Professor when he tries to kill Bourne. In The Bourne Supremacy (2004), Bourne breaks a gas line and burns a magazine in a toaster to blow up Jarda's house after he calls for CIA backup. In this film, Desh kills Daniels by blowing up his car which almost kills Bourne. There is another minor explosion in the chase scene where Jason Bourne is chasing Desh and Nicky. He throws an aerosol can into a fire to create a distraction.
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 federal police chief 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.
In the CIA substation where an 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)
Tony Gilroy, the main screenwriter of the earlier Bourne films, was hired by the studio to write a draft of the script to The Bourne Ultimatum (2007). Universal green-lit the film based on the draft, but Gilroy didn't do any revisions or rewrites because he was committed to his directing debut Michael Clayton (2007). In 2011 actor Matt Damon accused Gilroy for writing a quick draft for money and then leaving the project in turmoil. Damon called the original draft "unreadable" and potential "career-ender" for Gilroy, also saying that Gilroy arbitrated to get sole screenwriting credit before the movie came out (the Writers Guild of America turned the request down). Later Damon said it was "idiotic" for him to "blurt out" anything about the subject, since it was between himself and Gilroy (either they figure it out, or won't). In 2012 Gilroy said that he and Damon haven't spoken to each other "in years", although Gilroy later co-wrote The Great Wall (2016) which starred Damon.
Edgar Ramírez who plays an assassin in this film also played Ilich Ramirez SanchezCarlos (2010) in the TV miniseries Carlos. Carlos 'The Jackal' was the main antagonist in the Bourne trilogy written by Robert Ludlum albeit a bit different from the miniseries counterpart.
The Bourne series has many similarities to the Terminator series: it had 3 different directors, there were four movies, the main actor in the first 3 didn't appear in the fourth one, and only one won any Oscars while the other 3 weren't even nominated. The supporting actors from the Bourne and Terminator movies (Julia Stiles as Nicky Parsons and Earl Boen as Dr. Peter Silberman respectively) are the only actors who appear on the first three films with the main actor.
Tomas Arana, one of the actors from the previous film, The Bourne Supremacy mysteriously doesn't reprise his role as CIA director Marshall for this film. Instead he is replaced by Scott Glenn who plays the new CIA director Ezra Kramer.
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.
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.
Writing credits in early promotional material read: "Screen Story and Screenplay by Tony Gilroy, but Gilroy later retained sole screen story credit and received shared screenplay credit with Scott Z. Burns and George Nolfi following an arbitration conducted by the Writers Guild of America.
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.
Paz, the last 'operator' who's hunting Bourne, declines to shoot him (after listening to Bourne's line 'Look at us. Look at what they make you give'). The Spanish meaning of the related name 'Paz' is 'Peace'.
