History Trivia / DoctorWhoS31E6TheVampiresOfVenice

* WorkingTitle: ''Blood and Water'' and ''The House of Calvierri''

* DeletedScene: The script was originally too long, and as a result many sequences had to be cut, some even after they had been filmed. These included a fight scene with the Doctor and Rosanna's steward, a longer fight sequence between Rory and Francesco, and some dialogue between the Doctor and Amy following the climax.

* RecycledScript: The episode has similarities to "[[Recap/DoctorWhoS28E3SchoolReunion School Reunion]]", also written by Toby Whithouse. The pre-titles sequence involves a scene of a young girl being attacked by an alien and is followed by a scene in which the Doctor appears during a common activity and says something rather ordinary; the companion's boyfriend joins in for the adventure and becomes part of the TARDIS crew for the following episodes; both episodes feature scenes where two of the main characters discuss the Doctor's effect on relationships; the alien species in both episodes can transform into humans; the leader of the alien race in both episodes proposes an alliance with the Doctor; a minor character disposes of most of the aliens by causing an explosion; the alien's plan is thwarted by a simple flick of a switch; and both groups of aliens exhibited traits of vampire mythology.

** In the original script a big monster rose out of the water in Isabella's death scene, but this would have been too expensive and Creator/StevenMoffat was forced to ask Toby Whithouse to make it "invisible".
** The flower vendor was originally named Bianca.
** In the original script, Amy and Rory cornered Francesco after suspecting him of killing a villager and Francesco climbed up the wall. Toby Whithouse thought this would be a relatively easy stunt, but was told it would be too hard to accomplish and Whithouse revised it to when Francesco simply runs away.

* ActorInspiredElement: When discussing the script with Toby Whithouse, Creator/HelenMcCrory, thought that Rosanna should hurt Amy at some point and it was added that she bites Amy while she is in the chamber.

** Originally, the second half of the ColdOpen was placed after the opening titles, since the first scene of the episode ends with Isabella screaming, timed to the start of the title theme. However, as stated in the DVD commentary for the episode, the director thought the second scene of the episode (featuring the Doctor at Rory's stag party) ended with the same comedic awkwardness as the following scene, so they placed that scene as part of the cold open. Luckily, the effect of the first scene's end transitions well into the second scene, so it wasn't a huge loss.

* ActorAllusion:
** This isn't the first time Creator/HelenMcCrory has played [[Film/{{Casanova}} a Venetian woman concerned for her offspring.]]
** Also, does Karen Gillan being in a [[Recap/DoctorWhoS30E2TheFiresOfPompeii sort of creepy group of young not-so-human girls]] sound familiar?
** The Doctor says he'd rather not run into Casanova, presumably because he bears an uncanny resemblance to [[Creator/DavidTennant his last incarnation]].
