- Ability over Appearance: Fitz was described in the script as a "thin, wiry man with a sense of danger - a John Cassavetes type" who looked like he had spent some time in the army.
- Acting for Two: After departing the series, Christopher Eccleston makes cameos in "Men Should Weep" as a churchgoer and "Brotherly Love" as John Bilborough, David's brother.
- Dolled-Up Installment: The "Men Should Weep" storyline was originally conceived as a plot for Prime Suspect, in which Jane Tennison was raped.
- McLeaned: Bilborough and Beck were Killed Off for Real when Christopher Eccleston and Lorcan Cranitch wanted to leave the series.
- Playing Against Type: Robbie Coltrane was (and arguably still is) known primarily as a comedy actor, or else Rubeus Hagrid. First-time viewers may be shocked to see Coltrane playing a character who, while allowing for flourishes of wit and ribald humor, is extremely flawed and borderline unlikable. Coltrane won three BAFTAs for the role, proving himself a remarkably versatile talent.
- Tom Hanks Syndrome: Robbie Coltrane was primarily known as a comedic actor— until this cemented him as a dramatic actor.
- What Could Have Been: Robert Lindsay was the original choice for Fitz but turned it down.
