- Awesome Music: "Harlem Nocturne" by Earle Hagen, the theme song of the 1980's TV series, which Hagen wrote.
- Critical Dissonance: Critics hated the books back in the day, and to a large extent they still do, but there's no denying their popularity. Spillane himself joked about this."Those big-shot writers could never dig the fact that there are more salted peanuts consumed than caviar If the public likes you, youre good."
- Retroactive Recognition: For anyone who watched the short-lived FOX sitcom Titus, the guy who played Mike Hammer is the same one who plays Titus' hard-drinking, chain-smoking, wussy-hating, five-times-divorced dad, Ken.
- They Changed It, Now It Sucks!: Spillane was bitterly amused—at best—about the movie version of Kiss Me Deadly, for the changes it made both to the story (changing it from a Mafia-oriented yarn to one about a nuclear powder keg) and to Hammer himself (making him into a "divorce dick" who routinely pulls scams on both sides of the case).
- Values Dissonance: Hammer hates commies, queers and marijuana dealers with equal passion. When the character was watered down for the Stacy Keach series, his old fashioned values were often played for laughs; e.g. Hammer's love for cigarettes at odds with the growing social disdain for smoking.
YMMV / Mike Hammer
