History Trivia / DoctorWhoS33E4ThePowerOfThree

** Rory was supposed to have an action scene with two hospital assistants, which would’ve led into the Shakiri’s death.

** The in-universe Prime Minister, Stephen Carter, was supposed to have banned the Doctor Suspicious from the United Kingdom causing him to be absent from most of the story.

* CaliforniaDoubling: Amy and the Doctor's conversation outside the Tower of London could not be filmed at the genuine location due to the London Olympics, so it was shot on studio in Cardiff and the live action footage of them was composited with other footage of London, using visual effects to create the illusion.

** The emphasis of the story was heavily altered in post with a huge chunk of the Shakri scenes being removed. There was an extended action sequence in the climax in which Rory took down the two orderlies. The Shakri was not a hologram, and instead was defeated when Amy and Rory attacked him with the syringes retrieved from the orderlies, and the Doctor used his sonic screwdriver on the Shakri's devastating ocular weaponry. Much of this was removed because of Steven Berkoff's performance (see TroubledProduction below).

* ExecutiveVeto: Amy and Rory were originally supposed to stab Shakri to death with syringes. BBC Compliance effectively vetoed that plan.

* InspirationForTheWork: Creator/ChrisChibnall was inspired by the story of the MSC ''Napoli'', a 2007 shipwreck along the Devon coast near his home, when people showed up in droves to claim merchandise which had washed up on the shore.

** Creator/MattSmith put disgust into the Doctor's remark concerning Website/{{Twitter}} in the episode, reflecting his real-life decision to stay off the social network.

** One major element removed from the script was the appearance of Prime Minister Stephen Carter. Suspicious of the Doctor, Carter would bar him from the United Kingdom, resulting in the Time Lord's absence from a long stretch of the narrative.

** The episode originally ended with Amy and Rory deciding to take "one more" trip in the TARDIS despite Brian's unease. Creator/StevenMoffat suggested that this be changed to have Brian encourage them to go with the Doctor, providing a less sombre and more subtle lead-in to Amy and Rory's final story.

* CaliforniaDoubling: Amy and the Doctor's conversation outside the Tower of London could not be filmed at the genuine location due to the London Olympics, so it was shot on studio in Cardiff and the live action was combined with other footage to create the illusion.

** Kate Stewart's look of incredulous joy when the Doctor mentions her father -- and in fact Kate's undying love and admiration for her father in general -- is heavily influenced by actress Creator/JemmaRedgrave's own love and admiration for her own late father, Corin, who had passed away only a couple of years prior to filming this episode.

* RealitySubtext: Creator/MattSmith put disgust into the Doctor's remark concerning Website/{{Twitter}} in the episode, reflecting his real-life decision to stay off the social network.

* FirstAppearance: Of Kate Stewart.

* UnintentionalPeriodPiece: While the episode doesn't pile the contemporary pop culture references on ''quite'' as hard as many episodes from Creator/RussellTDavies' era did, there are nonetheless a few bits which instantly date the episode to the early 2010s, including the Doctor briefly playing with a UsefulNotes/{{Wii}}, and the boardroom line-up on ''Series/TheApprentice'' being Lord Sugar, Karren Brady and Nick Hewer.

** The episode was largely restructured to introduce the invasion storyline earlier. The episode originally began with scenes such as the adventure with Henry VIII and Amy at the engagement party.

* TroubledProduction: To say Creator/StevenBerkoff was difficult to work with was putting it mildly. He repeatedly went against the wishes of the director, in some cases just plain refusing to do what he was told, deliberately ruined takes (sometimes by reading his lines as badly as possible), and had several temper tantrums. Virtually ''all'' the footage they shot featuring Berkoff was unusable, and the ending as broadcast is all they could cobble together from the few scraps they were able to salvage, plus some pick-ups filmed later on with just Matt, Karen and Arthur (as well as some shots of Berkoff which were allegedly taken from when the camera was left running between takes, because even the filmed footage of Berkoff ''walking across the floor'' could not be used) — it was not originally the intention for Berkoff's character to be a hologram, or for the plot to effectively be resolved entirely by the sonic screwdriver, but that was all they were able to do with what they had. In an [[https://www.starburstmagazine.com/features/interview-douglas-mackinnon-director-of-doctor-who-series-7-episode-4-the-power-of-three interview given to promote the episode]], director Douglas Mackinnon barely attempted to conceal how difficult he found working with Berkoff:

* TroubledProduction: Steven Berkoff proved extremely difficult to work with, repeatedly going against the wishes of the director (or just plain refusing to do as he was told), deliberately ruining takes and having temper tantrums. The ending of the broadcast episode is significantly different to what was scripted, simply because many of the scenes filmed with him were unusable, and the ending had to be cobbled together from the little material they could use and pick-ups shot later on.

However, it was felt that this part of the episode detracted from the focus on Amy and Rory's life together.
