* AdaptationDisplacement: Nowadays, this film is arguably much better known than its source novel, any of the other Mike Hammer novels, and all the various film and TV versions of the other novels, even though most of them are TruerToTheText than this one.
* AluminumChristmasTrees: The movie is often credited for {{Deconstruction}} of the PrivateDetective protagonist by making Mike Hammer a SociopathicHero. Except, Mickey Spillane stated that was true in ''I, The Jury''. His sadistic PayEvilUntoEvil personality is TruerToTheText.
* RetroactiveRecognition: Creator/ClorisLeachman as Christina Bailey.
* TooBleakStoppedCaring: The movie has a very cynical view of life. The sympathetic characters are killed or seriously mistreated. The best anyone can hope to do is survive, and the film's ending even calls that into question.
