History Trivia / DoctorWhoS23E3TerrorOfTheVervoids

* ExecutiveMeddling: The ending of Part Eleven was supposed to be a model shot of the ''Hyperion III'' flying towards the Black Hole of Tartarus. Creator/JohnNathanTurner thought that all episodes of the "Trial" season should end on a close-up on the Doctor's face however (even though episode 9 memorably avoided that), and had the episode re-edited to end on a shot of the Doctor looking vaguely annoyed at Lasky. Fortunately, the special edition cut of this story (found in the Collection Blu-ray release) re-edits both scenes, and properly ends Part Eleven with the cliffhanger moment rather than a shot of Sixth's face.

* RealitySubtext: In Mel's first scene, she is putting the Doctor through an excercise and healthy eating routine, telling the Doctor "it's your waistline I'm concerned about". Creator/ColinBaker was struggling with weight gain at the time, and appeared noticeably more rotund this season than he had in Season 22.

* WorkingTitle: ''The Ultimate Foe'' and ''The Vervoids''.

* UncreditedRole: Because Creator/EricSaward walked out on the show following a spat with Creator/JohnNathanTurner over the planned ending to [[Recap/DoctorWhoS23E4TheUltimateFoe "The Ultimate Foe"]], Nathan-Turner had to perform script editing duties on this serial himself (as was also the case with part two of "The Ultimate Foe"). Because BBC guidelines prevented Nathan-Turner from taking credit as both script editor ''and'' producer, the former position goes unlisted in the closing credits. Creator/AndrewCartmel would eventually be hired to fill the void left by Saward starting with [[Recap/DoctorWhoS24E1TimeAndTheRani the next season's opener]].

* DawsonCasting: The role of Sarah Lasky was written for a woman in her forties, but was played by Creator/HonorBlackman, who was almost 60 at the time of taping.
