Trivia, insights & behind the scenes

Cultural

This aired two years before the first CSI lab opened in real life, making it prescient rather than derivative. Forensic pathology as entertainment didn't exist yet.

Trivia

Patrick O'Neal later played the villain in The Stepford Wives—a full career pivot from heroic pathologist to creepy suburban architect.
