One sequence in the beginning of the movie has John Wayne and Richard Attenborough sitting together at a private club when Attenborough notices that Wayne is carrying a revolver and hastens to point out that by doing that, it's placing him in violation of British law. Wayne quickly retorts, "Well it's not in violation of U.S. law and I work under the regulations of the Cook County Police Department which makes carrying it obligatory!" In reality, which law would actually take precedence there, U.S. or British? Anybody happen to know?
