The Day of the Doctor (TV story)

 was the fiftieth anniversary special of Doctor Who. The episode featured the return of David Tennant as the Tenth Doctor, and the appearance of John Hurt as a previously unknown incarnation of the Doctor; The War Doctor. Furthermore, the War Doctor was shown beginning a regeneration into the Ninth Doctor, resolving the matter of where and when this incarnation originated from that had stood unanswered since his debut in 2005.

The special also included the surprise debut of Peter Capaldi as the Twelfth Doctor, as well as a cameo from an elderly Tom Baker, the former Fourth Doctor, whose role was kept ambiguous as either the Doctor or someone else entirely — the Curator.

Synopsis
The Doctors embark on their greatest adventure in this 50th anniversary special. In 2013, something terrible is awakening in London's National Gallery; in 1562, a murderous plot is afoot in Elizabethan England; and somewhere in space an ancient battle reaches its devastating conclusion. All of reality is at stake as the Doctor's own dangerous past comes back to haunt him.

Story notes

 * The story uses the original opening sequence, modified to include a BBC logo.
 * With the regeneration of the War Doctor into the Ninth Doctor, every incarnation of the Doctor up to his current life has been depicted onscreen.
 * This episode marks the sixth televised Multi-Doctor story, not counting the times he meet his past or future self in the same regeneration.
 * Two specially recorded scenes were shown before the special in its showing in cinemas. The first featured Dan Starkey as Commander Strax, accompanied by his Sontaran clone batch, lecturing the viewers on cinema etiquette. The second featured Matt Smith and David Tennant as the Eleventh and Tenth Doctors instructing viewers to put on their 3D glasses.
 * Discounting the appearance of the Valeyard in The Trial of a Time Lord, this is the first story to feature a future Doctor before their official debut.

Production errors

 * As Osgood receives a call from the Eleventh Doctor, for Kate Stewart, she is heard talking on the phone but is seen running with the phone held out from her body.
 * When the Tenth Doctor proposes to Queen Elizabeth, a horse can be seen in the background. As he accuses her of not being human, the horse can be seen having changed positions to face them and back between camera shots.

Continuity

 * Clara is now a teacher at Coal Hill School. A sign shows that Ian Chesterton is chairman of the school's Board of Governors. The sign for the I.M. Foreman Junkyard is still in existence next to the school. (TV: An Unearthly Child)
 * The Tenth Doctor's wedding with Elizabeth I is shown (TV: The Shakespeare Code, The End of Time, The Beast Below). Presumably, the fact he indicates no intention of returning to his new wife is what results in her antagonism towards him when they next meet. (TV: The Shakespeare Code)
 * The Eleventh Doctor refers to his fate on Trenzalore. (TV: The Wedding of River Song, The Name of the Doctor)
 * The Tenth Doctor, when returning to his own timeline, tells the Eleventh Doctor that he is glad his "future is in good hands." These are the exact same words the First Doctor says to the Fifth Doctor upon the former's departure. (TV: The Five Doctors)
 * The Tenth Doctor, upon hearing of Trenzalore, says they need to take a different direction as "I don't want to go." His successor notes that "He always says that.", being his last words before his regeneration. (TV: The End of Time)
 * When the War Doctor enters the Tenth Doctors TARDIS he says he really "let it go", the Eleventh comments that this was his grunge phase. When the Eleventh Doctor enters the Tenth Doctor's TARDIS console room he loads his own "desktop" changing the TARDIS design, The Tenth declares he doesn't like it. Both of these reference the Second Doctor when he saw the Third Doctor's TARDIS (TV: The Three Doctors), and the Eleventh Doctor when visited Craig Owens in his new home. (TV: Closing Time) The TARDIS told the Doctor that she archived past and future versions of the console room in The Doctor's Wife. While changing the theme, the console room briefly features a hybrid of the Tenth Doctor's console room and the original TARDIS roundel design. The War Doctor's TARDIS is later seen using this theme during the envelopment of Gallifrey.
 * This is the first televised appearance of the Zygons since TV: Terror of the Zygons.
 * Prior to regenerating, the War Doctor comments that his body is "wearing a bit thin", repeating the line spoken by the First Doctor immediately prior to his regeneration into the Second Doctor. (TV: The Tenth Planet). He then hopes that "the ears will be a little less prominent this time"; the Ninth Doctor makes a reference to the size of his ears in TV: Rose, which presumably takes places shortly after from the Doctor's point of view.
 * The Black Archive of UNIT appears. (TV: Enemy of the Bane, COMIC: Don't Step on the Grass)
 * A pair of red heels identical to the ones River wore on the Byzantium are seen in the Black Archive. (TV: The Time of Angels)
 * This is the first time all the Doctors of all regenerations come together.
 * The Tenth Doctor asks the Eleventh where he's going and the Eleventh Doctor replies, "Spoilers." (TV: Silence in the Library / Forest of the Dead et al.)
 * The Tenth Doctor uses a machine similar timey-wimey detector (TV: Blink), this one detects shapeshifters.
 * The Eleventh Doctor calls to Clara through a wormhole, referring to her as the "Wicked Witch of the Well." Hila Tacorien was previously referred to by this name due to the wormhole in Caliburn House. (TV: Hide)
 * Clara had not previously visited the Black Vault. However, she was surprised to find she had previously been vetted and granted high-level access. Photos of her and Kate Stewart are pinned to a board showing all of the Doctor's companions; however, this is the first time they have met from Clara's point of view.
 * Kate asks Osgood to tell "Malcolm" to change the batteries in the robotic ravens outside the Tower of London, and later calls Malcolm to request some of her father's files. This could be a reference to Malcolm Taylor, a UNIT scientist the Tenth Doctor met during his time on San Helios with the Swarm. (TV: Planet of the Dead)
 * The Time Lords in the War Room mention that the High Council are holding an emergency session, and that they have plans of their own. This session is presumably the one depicted in (TV: The End of Time), in which the Lord President planned to use the Master to allow Gallifrey and the Time Lords to escape the time lock.
 * The War Doctor and his successors were plagued by the children they killed by using the Moment. When the Eleventh Doctor took Amy Pond to Starship UK, he couldn't stand the sound of children crying. (TV: The Beast Below)
