History Trivia / InsideNo9

** Shearsmith has stated on social media that he wanted to fit more details about the Oakwood family into ''3 By 3'', including that Stephen used to own a law firm, and that he had always been terrified of Catherine while Margaret took advantage of her powers.

** At a preview screening of Season 3, the creators claimed that when writing "The Bill", they found it difficult to decide whether Creator/PhilipGlenister's character should be an UpperClassTwit or a brash nouveau-riche type, and alternated between the two in different drafts of the script. The latter was chosen for the final episode.

* TakeThat: The creators have stated that the character Angel in "Thinking Out Loud" is based on a social media influencer whose behaviour they considered selfish.

** In an [[http://www.bbc.co.uk/blogs/writersroom/entries/61e0081d-6a37-4630-9893-8b5880749e1a interview]] with the BBC's Writer's Room website, Pemberton revealed that an earlier version of Series 1's "The Understudy" would have featured [[{{Series/Psychoville}} David and Maureen Sowerbutts]] with Maureen as a Lady Macbeth-type character persuading David to murder his co-stars and secure a bigger role. It was later decided that "ultimately though it didn't feel right to mix up the worlds like that, and Inside No. 9 had to earn its own place in the comedy universe without leaning on our past work." [[spoiler: David and Maureen did eventually appear in Series 5's "Death Not Be Proud", although in a very different story to the idea shown above.]]

** ''The Devil of Christmas'' was supposed to be a straight story about the TheKrampus; but Shearsmith and Pemberton re-wrote the script after discovering there is a [[Film/{{Krampus}} recently released horror movie]] about Krampus.
