While not under any circumstance a film noir and containing nothing within its narratives nor stylings which might help classify it or tend it towards discussing in the film noir for a of our own reflective times, 49th Parallel (1941) does depend on themes of espionage and manhunting , while also and most curiously profiling Nazis as the protagonists.
This is an effective narrative route, for the large part because Powell and Pressburger did not make films which heavily patronised, satirised, demonised and ridiculed the Third Reichers of the early 1940s.
