Trivia / Doctor Who S34 E11 "Dark Water"

---

• Ascended Fanon: This is the first time within the TV canon that a Time Lord has been confirmed to have changed sex during regeneration, confirming a long-helf belief in the fandom that was previously alluded to in "The Doctor's Wife"
• Completely Different Title: The French title is "La Nécrosphère", after the Dub Name Change for the Nethersphere.
• Foiler Footage: An alternate version of the scene where Missy claims her name is an acronym of "Mobile Intelligence Systems Interface" was shot with her claiming she was a "Random Access Neural Interface". The outside scenes of her revealing her identity to the Doctor were shot with Gomez miming that she was the Rani to throw off anyone watching filming who could lipread. The close up of her saying "Master" was filmed later and other dialogue filled in with ADR.
• Schedule Slip: The death-related content of this episode resulted in an eleventh-hour decision to reclassify this episode in the UK, triggering the necessity of delaying the Series 8 DVD/Blu-ray box set release by a week in order to allow the boxes to be reprinted with the new rating.
• What Could Have Been:
  • According to Michelle Gomez, one take of the sequence where Missy kisses the Doctor originally showed her also holding Clara's hand.
  • The filming reports showed the graves for Clara Oswin Oswald, Ellie Oswald, and Amy and Rory, suggesting that they were originally going to have been indicated to have become Cybermen.
