This movie shows us that David Webb was previously a Captain in the U.S. Army 1st Special Forces Delta (1st Special Forces Operational Detachment-Delta , "1st SFOD-Delta"), otherwise known as the Delta Force. In the Robert Ludlum Novels, Bourne's operational code name in the military (Before joining Treadstone-71) was "Delta."
Matt Damon admitted that physically training for the role of Bourne was much harder in his forties, and he had to keep to a very strict diet to maintain his physique during filming.
The Las Vegas car chase sequence took five weeks to shoot and at the end, the sequence wrecked 170 cars.
Since part of the story takes place in Athens, Greece, the producers asked the Greek Government for permission to shoot the film in the actual location. Due to high taxes and bureaucracy, this never happened. Tenerife, in the Canary Islands, doubles as Athens in the movie.
City officials and the producers reached an agreement to only shoot the Las Vegas car chase sequence from midnight to sunrise.
Matt Damon has stated numerous times that he would only return to the Bourne series to reprise his role as Jason Bourne if Paul Greengrass would return for directorial duties on the project. Damon and Greengrass announced their return in November 2014 for a new installment.
