- Award Snub: Truman Capote was highly annoyed that the 1967 film version wasn't nominated for the Best Picture Oscar, and yet the musical dud Doctor Dolittle was.
"Anything allowing a Dolittle to happen is so rooked up it doesn't mean anything."
- Harsher in Hindsight: Robert Blake, who played Perry Smith in the 1967 film, became a real life murder suspect in 2001.
- Ur Example: Although this piece of work is often credited as the first Non-Fiction novel, in fact In Cold Blood appeared nine years later than Operation Massacre, from the Argentinian journalist and writer Rodolfo Walsh. The late was published in 1957, and was well-known at the moment.
- Also "Un millón de muertos" ("One Million Dead"), from the spanish writer José María Gironella Pous, is from 1964, two years prior to Capote's work.
