Day of the Daleks (TV story): Difference between revisions

* This story is noted for being one of only a very few in which time travel is used as a main plot element.

* The mind analysis machine sequence represents the first occasion that images of [[William Hartnell]] or [[Patrick Troughton]] had appeared in the show since their departures from it. The next occasion they would be seen on screen (and the only other occasion this occured in the Pertwee era) was when they both guest starred in ''The Three Doctors''.

** ''[[Bringer of Darkness]]'', in [[1993]], would have had the Second Doctor encounter the Daleks after ''Evil'' and learn that the Humanized Daleks had been destroyed.

* This is the first Dalek story since ''[[The Daleks]]'' in which there is no change to the main cast (if ''[[The Power of the Daleks]]'' is seen to introduce the character of the [[Second Doctor]]).

* The Ogrons are not named or described in Louis Marks's original scripts, being indicated merely by the term 'Monster'.

* Nicholas Courtney is credited as '''The'' Brigadier' in ''Radio Times'' for episode two.

* Tim Condren (Guerilla) is credited in ''Radio Times'' as 'Guerrilla' — a misspelling, with two 'r's.

* John Scott Martin (Dalek) is credited as 'Chief Dalek' in ''Radio Times''; while Ricky Newby and Murphy Grumbar are both credited on-screen, but not in ''Radio Times''.

* George Raistrick (Guard at Work Centre) is credited as 'Guard' in ''Radio Times''.

* This is the first story in which the Doctor encounters — and actually interacts with — another version of his current incarnation (in the scene in episode one where the Doctor is tinkering with the TARDIS console, and he and Jo meet future versions of themselves). It was originally intended that in episode four the Doctor and Jo would meet their episode one selves (this time, they would ''be'' the 'future selves'), and the audience would thus realise where the future doubles had come from. But the scene was another that had to be dropped because episode four was overrunning. Indeed, this is the first story in which the Doctor meets himself, whether the same or another incarnation (since this serial was broadcast a full year before ''The Three Doctors'').

* In episode two, when the Controller tells Jo that she has already told him the year and goes on to ask where and when the Doctor is, she gives the date as "September the 13th" — a production team in-joke: this was a reference to the first of the four days of location filming for the story, which took place from Monday 13th to Thursday 16th September, 1971.

* Discounting a couple of brief cameos, the Daleks had not appeared in ''Doctor Who'' since ''[[The Evil of the Daleks]]'' in [[1967]]. With this story, they returned to being regular opponents of the Doctor, making annual appearances every year for 4 years, before going into hibernation again after [[Season 12]]. A new sound effect for the Dalek energy weapon is introduced (but not used since).

* Every serial of the [[Season 8|preceding season]] ([[1971 (releases)|1971]]) featured {{Delgado}}. As such, this was the first serial broadcast in eighteen months - specifically, the first time since [[TV]]: ''[[Inferno (TV story)|Inferno]]'' - in which he does not appear. He was, however, absent from Episode 1 of [[TV]]: ''[[The Mind of Evil (TV story)|The Mind of Evil]]'' and the first three episodes of [[TV]]: ''[[Colony in Space (TV story)|Colony in Space]]''. He would re-appear next in [[TV]]: ''[[The Sea Devils]]''.

* Near the end of episode two, the Doctor fires one of the guerillas' disintegrator guns at an Ogron, vaporising it. This is one of only a handful of occasions in the franchise's history that the Doctor uses deadly force with a firearm (as in ''The Keeper of Traken'').

* In the novelisation of this story, the [[Gold Dalek]] is replaced by a [[Black Dalek]]. However, the Gold Dalek still makes an appearance, as the Black Dalek's superior.

* That Terry Nation was not consulted in advance about the use of the Daleks in this story and, when he found out about it, it led to a row between him and the BBC. ''(Although [[Terrance Dicks]] recalls such a dispute, [[Barry Letts]] does not, and it is clear from contemporary BBC documentation that it is Letts who is correct. Nation was consulted in advance, and his agents, ALS Management, confirmed in a letter dated 22 April 1971 that he had no objection to the Daleks being used in a story for the 1972 season, subject to the usual negotiations.)''

* That this was the first Dalek story not written, or co-written, by [[Terry Nation]]. ''([[The Power of the Daleks]] and [[The Evil of the Daleks]] were written by [[David Whitaker]].)''
