- Didn't Think This Through: When taken to task by viewers on Biteback, two of the personnel involved in the show's creation admit that, having thrown themselves into producing a ghost story with a contemporary spin, they were woefully underprepared for the possibility that swathes of viewers would be taken in by the show's premise.
- Executive Meddling: The writing credit at the opening was a last minute addition insisted on by the BBC, who had very nearly pulled the entire broadcast.
- Other ideas that were pulled of consultation with BBC higher-ups were the inclusion of a high-pitched frequency that would agitate any dogs proximate to the TV during broadcast and a line delivered by possessed Parkinson telling viewers that "the ghost" is probably in their house".
- Hey, It's That Guy!: A number of BBC presenters from the time, but particularly Craig Charles of Red Dwarf and Robot Wars fame.
- Shown Their Work: Writer Steve Volk and producer Ruth Baumgarten consulted with representatives of a number of psychical societies as well as members of the public professing to experiences with the paranaromal, with the result that the programme gives a veritable checklist of phenomena associated with the ghosts. Inversely, next to no research was done on the possible adverse reactions a suggestible viewer might have to the show (see Didn't Think This Through note above).
- Unintentional Period Piece: Ghostwatch has a distinct Nineties feel, aping then-emerging docudramas like Crimewatch and making use of technology that was in vogue at the time, such as the light pen and the infrared vision (the latter commonly used on Gulf War reports).
