* ActorAllusion: Sigourney Weaver's tourist character gets on Mrs. Tishall's nerves. In RealLife, Selina Cadell (Mrs. Tishall) and Weaver are best friends.
* TheDanza: Martin Clunes as Dr Martin Ellingham. Further variant in that the character's surname is an anagram of series creator Dominic Minghella.
** Suffered from this at first due to Martin Clunes being well known for playing Gary on ''Series/MenBehavingBadly'', but this has decreased over time as he has become equally famous for this role.
** ''Series/DoctorWho'' fans will notice at least six familiar faces. [[Creator/MartinClunes Lon]] from [[Recap/DoctorWhoS20E2Snakedance "Snakedance"]] is now Portwenn's GP, where [[Creator/IanMcNeice Winston]] [[Recap/DoctorWhoS31E3VictoryOfTheDaleks Churchill]] is an all-purpose entrepreneur. Louisa's mother is [[Creator/LouiseJameson Leela]]. [[Creator/TomGoodmanHill Reverend]] [[Recap/DoctorWhoS30E7TheUnicornAndTheWasp Golightly]] unsuccessfully tried to sell black-market foodstuffs at one point, and [[AnneReid The]] [[Recap/DoctorWhoS29E1SmithAndJones Plasmavore]] became a CrazyCatLady. And, in an earlier episode, [[Creator/DebbieChazen Foon]] [[Recap/DoctorWho2007CSVoyageOfTheDamned Van Hoff]] mistakenly gave her daughter caffeine-laden "diet pills."
** [[Series/DeathInParadise DI Richard Poole]] apparently also has a giant squirrel for a friend...
* McLeaned: Aunt Joan was killed off after Stephanie Cole chose not to return for Series 5. The character was a fixture in the setting and Martin's life, so killing her off was probably the most plausible explanation for her sudden disappearance.
* PlayingAgainstType: Ian [=McNeice=] usually plays characters who are, if not posh, at least of a high status in their sphere. Here, he plays the decidedly working-class Bert Large.
