The Christmas Invasion (TV story): Difference between revisions

* The Doctor's speech to PM Harriet Jones about how "[[Earth]] is drawing attention to itself" recalls a similar statement made by [[the Brigadier]] in [[TV]]: ''[[Spearhead from Space]]''. Jones's destruction of the Sycorax ship and the Doctor's angry reaction are similar to the conclusion of [[TV]]: ''[[Doctor Who and the Silurians]]'', in which the Brigadier uses explosives to seal off the [[Silurian]] hibernation chambers even as the Doctor departs to begin peace negotiations.

* [[United Kingdom]] had manned missions to [[Mars]] previously featured in [[TV]]: ''[[The Ambassadors of Death]]'' and [[PROSE]]: ''[[The Dying Days]]''.

* The [[Ice Warrior]]s are actual Martians. ([[TV]]: ''[[The Ice Warriors (TV story)|The Ice Warriors]]'')

* The Robotic Santas reappear in [[TV]]: ''[[The Runaway Bride]]''.

* The Doctor regrows his severed hand, establishing a notable new twist to the mechanics of [[regeneration]] and, in part, suggesting a rationale for [[Romana II]]'s ability to change her appearance several times during regeneration in [[TV]]: ''[[Destiny of the Daleks]]''. The Doctor's severed hand, last seen falling to earth in this episode, is later retrieved by [[Jack Harkness]]. ([[TV]]: ''[[Everything Changes]]'', [[TV]]: ''[[Utopia (TV story)|Utopia]]'') Much later, it would return to the Doctor. ([[TV]]: ''[[Last of the Time Lords]]'') After the Doctor used it as a receptacle for regeneration energy, something compelled Donna to touch the hand, enabling it to grow into the [[Meta-Crisis Tenth Doctor]] (and also turning Donna into the [[Doctor-Donna]]). The real Tenth Doctor subsequently took the Meta-Crisis Tenth Doctor to [[Pete's World|the parallel universe]], leaving him to live out his life there with [[Rose Tyler]]. ([[TV]]: ''[[Journey's End]]'')

* This is actually the second time the Doctor has lost a hand in combat, as the [[First Doctor]] sported a bioengineered replacement hand for most of his adventures. ([[PROSE]]: ''[[A Big Hand for the Doctor (short story)|A Big Hand for the Doctor]]'')

* In the scene inside the TARDIS' wardrobe room near the end of the episode, various articles of clothing worn in earlier episodes are visible, including one of [[Steven Taylor]]'s shirts (worn in [[TV]]: ''[[The Celestial Toymaker (TV story)|The Celestial Toymaker]]''), what may be the [[Sixth Doctor]]'s waistcoat from ''[[The Two Doctors]]'', the [[Second Doctor|Second Doctor's]] trousers, and the [[Fifth Doctor]]'s panama hat, as well as what appears to be the [[Fourth Doctor]]-like costume that the [[Seventh Doctor]] wore in [[TV]]: ''[[Time and the Rani]]''.
