Carter Wood points to a BBC interview with Dark Knight co-star Aaron Eckhart:
Lang: The movie’s already done incredibly well. I think it’s broken records in its opening weekend in the United States. I mean, do you think that because America’s in an election year, the economy going down the tubes, a lot of uncertainty in the world, do you think it touched a nerve?Eckhart: (Laughs) You’re very anti-American here.Lang: Yes?Eckhart: We’re having our problems…First of all, I will never disparage America on foreign soil. I am a proud American.
