Trivia: Prime Suspect
- Actor Allusion: Tennison to a profiler (who has a photo of the female victim posing with a gun): "Putting together a calendar?".
- Hey, It's That Guy!: Zoe Wannamaker, Ralph Fiennes, Tom Wilkinson, Peter Capaldi, David Thewlis. And of course Helen Bloody Mirren.
- Hey, It's That Voice!: Anthony "C-3PO" Daniels as The Coroner. Perhaps subverted, as he actually appears on screen as an actual person.
- Gaz/Ghost/Wallcroft as DI Frank Burkin.
- What Could Have Been: Jimmy McGovern said that he was expecting to be asked to write an episode where Jane was raped, but then Cracker happened and he used the storyline for that instead.
- Word of Gay: In March 2015, Mirren was asked what Jane Tennison would be doing now. She replied "She's a lesbian, living with a very attractive female partner."
