Cold Case

Trivia

• The show's theme song is "Nara" by E.S. Posthumus, who also made the song Posthumus Zone for CBS Sports' The NFL Today and The NFL on CBS.
• Each show makes extensive use of era-appropriate music for flashbacks to the year in question.
• Cold Case is notable for double-casting: it will cast a young actor for the flashback sequences and a more seasoned actor for the shots in the present, and cut back and forth between the two, to show how the character has aged.
• Nearly every show ends with a set of scenes showing the murder, Detective Rush arresting the murderer and seeing the grateful-looking victim standing nearby, who then quickly vanishes (this aspect of the show is meant to represent Rush's imagination, since the show is not about the supernatural).
• A real life "cold case" investigative organization, known as the Vidocq Society, is based in Philadelphia, and may serve as inspiration for the show's theme and location.
