Again, WW2 propaganda, however, this film is interesting in challenging everything Europeans know about war and peace by playing the idea that WW2 is a war of existence and England and the allies must fight beyond the 19th century notion of "Rules of War" because otherwise it wouldn’t be a gentlemanly loss but complete and utter genocide.
The filmmaking is becoming perfect. The colors are very nice, not completely unrealistic and aiding the tone and understanding of the story rather than working against selling it as a convincing world. The team of Powell and Pressburger almost burst onto the scene with this movie making a name for themselves as visually bold, big production value filmmakers. They are showmen in the complete sense of the word. There's a lot of theatricality to this film and the performances as well as the colors and production design. It is a bit grandiose yet still rooted in reality.
Again, we are seeing the anti-hero, the protagonist who learns to bend the rules, coming to the fore as WW2 reshapes the literary identity of the world. WW2 really seems to usher in the modern era of morals being flexible and the line between good and evil being almost wiped away whereas WW1 just shook the identity to its foundation.
This film has great set pieces from the various trenches to the bathhouses in London. It really sells you on a time and place of London during the War.
