- Hey, It's That Guy!: Intentionally invoked for the YouTube revival; Google brought in Isy Suttie and Jessie Cave "at no small expense".
- Screwed by the Network: Despite consistently rating as CITV's most-watched show until the very end of its life, the network suits decided that the show was yesterday's news and coerced the producers into allowing Knightmare to die so that Virtually Impossible could have a second season... and then they cancelled Virtually Impossible anyway.
- What Could Have Been:
- One dungeoneer had a very near miss in the Corridor of Blades, and the suggestion was made that he should appear to have lost an arm (by covering that arm with green fabric, so it would be removed by the greenscreen effects). Executive Meddling vetoed the idea.
- An American adaption was tried in 1993, called Lords of the Game; the pilot was filmed in Norwich, using American contestants. Unfortunately, American producers balked at the complexities of the chroma-key gameplay and it wasn't picked up. (A NYC/Long Island-based independent station, WLNY-TV 10/55, did air reruns of the original show in the mid-90's.)
