- Backed by the Pentagon: The London Metropolitan Police came to support the show and the actors were allowed to wear accurate uniforms and use real police equipment.
- Billing Displacement: For the first three seasons, Eric Richard (as Sgt Cryer) and John Salthouse (Inspector Galloway) were always given top billing in the end credits. Not entirely surprising, as those two characters could probably very legitimately be seen as the central stars in the early years. After Salthouse left the series in its fourth season and the format changed to half hour episodes, the tradition continued for another few years with Eric Richard always recieving top billing, regardless of whether Cryer was actually the central character of that given episode or not.
- Executive Meddling: The format has been gradually fiddled about with ever since the decision to move to half-hour episodes in 1988, eventually getting to the point where it (arguably) no longer resembled its previous self.
- Outlived Its Creator: Geoff McQueen, who wrote the original Pilot Episode and created the series, died in 1995. The series he created kept going until 2010.
- Real-Life Relative: Michael Higgs (PC Eddie Santini) is married to Caroline Catz (PC Rosie Fox).
- Screwed by the Network
- You Look Familiar: A lot of regular cast members previously appeared in the show as other characters, including Russell Boulter (DS John Boulton), Clara Salaman (DS Claire Stanton), Steven Hartley (Supt. Tom Chandler), Rene Zagger (PC Nick Klein) and Chris Simmons (DC Micky Webb).
