Do you literally have to live in the U.S. to knock its values or criticize its culture or politics? David Cronenberg, a Canadian whose recently-screened A History of Violence addresses America’s shoot-em-up, fistifcuff tendencies, is quoted thusly by L.A. Times critic Kenneth Turan: “Does a fish know about water? Living in a tributary, not the ocean, [Marshall] McLuhan had a different perspective. The insights he had into America would not be possible to anyone living in America. Stepping away has a lot to do with it.”
