Director Paul Greengrass explicitly cited Gillo Pontecorvo's The Battle of Algiers (1966), the Italian-Algerian political thriller shot in documentary-style verite. Greengrass absorbed Pontecorvo's approach to staging chaos—hand-held cameras, crowded streets, violence that erupts from the everyday. Bourne's final hand-to-hand combats move with the urgency and grit of an underground resistance, not a spy thriller.
