The 2000 film associated with Steven Soderbergh's Best Director Oscar win was Traffic.
Traffic is a 2000 crime drama directed by Steven Soderbergh. The film examines the illegal drug trade from several connected viewpoints, including a Mexican police officer, American law-enforcement officials, a judge appointed to fight drugs, and a teenager whose drug use devastates her family. Its interwoven structure emphasizes that the problem cannot be reduced to a single person or location.
At the 73rd Academy Awards, honoring films released in 2000, Soderbergh won Best Director for Traffic. The achievement was unusual because he had also been nominated in the same category for Erin Brockovich, another film he directed that year. Traffic won four Oscars in total, including Best Supporting Actor for Benicio del Toro, Best Adapted Screenplay, and Best Film Editing.
The wording can cause a small conceptual mix-up: the Academy award went to Soderbergh, not literally to the film. In ordinary trivia usage, however, Traffic is the single canonical film answer because it was the winning directing entry.
