This was one of several films mentioned in the September 1941 Senate subcommittee hearings on Propaganda in Motion Pictures, where isolationist senators Nye, Clark and Wheeler attacked Hollywood for "war-mongering." Senator Nye, who testified before the committee, had not seen most of the films mentioned. The subcommittee did not reconvene after September due to the attack on Pearl Harbor in December. The featurette included on the 2009 DVD release contends that the making of war-mongering films would be a violation of the Neutrality Act, which focused on restricting arms sales to belligerent nations, regardless of their status of aggressor or defender.
When Thorndike (Pidgeon) is captured, the George Sanders character inspects his belongings including his rifle, which bears the maker's name of "Hammond and Hammond, Bond Street". There was no such gunsmith in the UK and it seems likely the name is borrowed from a very famous gunsmith called Holland and Holland of Bruton Street, which is situated nearby.
