Soderbergh called Traffic his "$47 million Dogme film" and used hand-held camera, available light, and (ostensibly) improvistational performance in an attempt to present a realistic story about illegal drugs. He prepared by analyzing two political films made in a realist style: Battle of Algiers (Gillo Pontecorvo, 1966) and Z (Constantin Costa-Gavras, 1969), both of which he described as having "that great feeling of things that are caught, instead of staged, which is what we were after."
Q: "Who are some of your biggest cinematic influences?" Costa-Gavras: "The first movie I saw at the Cinematheque was [Erich von Stroheim's] Greed, and I was astonished to see you could do long movies with no happy ending. Kurosawa, no doubt, was a big influence. Movies sometimes more than directors have influenced me: The Grapes of Wrath, by John Ford, was an extraordinary discovery. Sergei Eisenstein, of course. Later on, [Ingmar] Bergman."
Affleck: "I haven't done a movie that I haven't ripped off from another one! [Laughs.] This movie, we ripped off All the President's Men, for the CIA stuff, a John Cassavetes movie called The Killing of a Chinese Bookie, which we really used as a reference for the California stuff, and then there was kind of a Battle of Algiers, Z/Missing/Costa-Gavras soup of movies, that we used for the rest of it."
