* There were going to be more scenes focusing on the Duke of Manhatten and Frau Clovis.

* SparedByTheCut: The Face of Boe was going to die in this episode and reveal his message, and the Doctor forced to let the care patients die to cure them. Davies apparently changed his mind after reading Creator/StephenMoffat’s introduction for the book ''The Season One Shooting Scripts''. He joked about how Davies "creates interesting characters and then melts them", which helped change Davies’ mind and create a happier ending. The Face of Boe was also kept around, both because of Creator/BilliePiper’s decision to leave after Series 2, and the show’s renewal making Davies push it back to fit with that season.

* SparedByTheCut: The Face of Boe was going to die in this episode and reveal his message, and the only way for the Doctor to cure all the diseased was to euthanize them all. The Face of Boe was kept alive both because of Creator/BilliePiper’s decision to leave after Series 2, and the show’s renewal making Davies push it back to fit with that season. He was also influenced by Moffat ribbing in the introduction about how he "creates interesting characters and then melts them".

** Originally, the Face of Boe was to die and deliver his message to the Doctor in this episode. Davies postponed the revelation after the series was renewed for another season.

* EnforcedMethodActing: Creator/BilliePiper didn't know she was going to be hit with water in the lift. Creator/RussellTDavies kept it in the final cut as he thought it was too funny to cut it.

* SparedByTheCut: In the original script, the Face of Boe was going to die in this episode (and thus impart his secret to the Doctor a year earlier) and the only way for the Doctor to cure all the diseased was to euthanize them all. But then Creator/RussellTDavies read Creator/StevenMoffat's introduction segment in ''The Season One Shooting Scripts'' book, in which Moffat good naturedly mocked Davies, saying he "creates interesting characters and then melts them". This made Davies decide to have them all survive instead. The Face of Boe was spared because his final message was felt to work better in Series 3.

** Because production fell behind schedule, several scenes were dropped. Many of these concerned the Duke of Manhattan and Frau Clovis. Originally, they first appeared in the hospital foyer when the Doctor initially arrives; as scripted, the Doctor immediately earns the Sisters of Plenitude's disfavour when he saves the Duke's life. Later, Clovis mutinies when the Duke refuses to help defend the hospital against the Intensive Care patients. Another scene that was lost was a moment that would've bridged the gap between the Doctor and Rose leaving the hospital with Cassandra and arriving at the party where she dies in Chip's body. The missing scene would've had the Doctor making clear he hadn't forgotten the deaths Cassandra caused on Platform One during [[Recap/DoctorWhoS27E2TheEndOfTheWorld "The End of the World"]] and added more context to Cassandra's death scene.

** Cassandra's servant was envisioned as a dwarf named Zaggit, but as the character's importance grew during the scripting process, he developed into Chip.
** Had Creator/ZoeWanamaker been unavailable for filming, Davies would have introduced her evil sister "Roseanne".
* WordOfGod: According to Creator/RussellTDavies on the DVDCommentary, Cassandra's earlier self bases Chip on the man who had praised her beauty at the party — Chip himself. Where the "pattern" for Chip comes from in the first instance is thus unclear, creating an ontological paradox.
* WordOfSaintPaul: In the DVDCommentary: Creator/DavidTennant noted that the TARDIS has moved since "[[Recap/DoctorWho2005CSTheChristmasInvasion The Christmas Invasion]]". He speculates that there might have been many off-screen adventures, or (observing that it no longer seems like Christmas in the introduction) perhaps that the Doctor "lived there for a bit".

* BuxomIsBetter: Creator/BilliePiper's physical transformation from Rose to Cassandra was all about support. For her Cassandra scenes, she put on a different shade of lipstick, and wore a Wonderbra to enhance her cleavage and make her character a bit more shapely (in some shots, the outline of the bra is visible through her shirt).
