Jerry Herron, professor of American Studies, comments about the newly released film "United 93," an intense dramatization of the hijacked United Airlines flight that crashed in rural Pennsylvania on Sept. 11, 2001. Herron says at least by Hollywood standards, the time is right for a film like "United 93." "It's close enough to retain its historical power but not far enough away that people will have forgotten the details," Herron says. He adds that throughout American history, movies have helped shape our world view and enabled us to come to grips with events that have rocked us to our core. "Maybe more than any other people, we've used movies to try and define our historical consciousness of what's going on and what it means," Herron said. "Films are how we tell each other how we felt about things that have happened to us."
