The Return of Doctor Mysterio (TV story)

The Return of Doctor Mysterio was the 2016 Doctor Who Christmas special. It was the show's twelfth Christmas special since its revival, and the third Christmas special starring Peter Capaldi as the Twelfth Doctor. It saw the return of Nardole from the previous Christmas special, this time as the Doctor's companion. The circumstances leading to Nardole's return were not explained until 2017's Extremis. It also marks the first time since the Christmas special A Christmas Carol that the title of a pre-existing story related to the holiday has not been used as the title for a Doctor Who Christmas special.

The following day, The Return of Doctor Mysterio was granted a sequel entitled Ghost Stories. This story made the Ghost, Lucy and baby Jennifer all companions of the Twelfth Doctor.

Steven Moffat was hugely influenced by the comic books he loved as a child in writing this episode—particularly Clark Kent, Moffat's favourite superhero, both then and now. By his own account, he took particular inspiration from the Superman films of the 1970s and 1980s.

Though clearly humorous in tone, The Return of Doctor Mysterio explores many common superhero themes, such as the hero's secret identity, his origin story, and a love triangle involving both the hero and the man behind the mask.

Synopsis
The Doctor once more faces off with an alien species that wishes to conquer the planet: Shoal of the Winter Harmony. This time, he has more backup than usual; however, this help was a little twist to it: it's a superhero called the Ghost.

Plot

 * Christmas Eve, 1990s
 * New York City

A young boy named Grant wakes up during the middle of the night to find the Doctor swinging from his ankles in front of his bedroom window. Grant, believing the Doctor is Santa Claus, lets him in and feeds him cookies. The Doctor hands Grant a red gemstone and a glass of water, and two discuss superhero comics, of which Grant is a fan. The Doctor leads Grant to the roof of the apartment, where he reveals a device that he is unable to describe in simpler terms than a "time distortion equaliser thingy". He instructs Grant on how to power up the device, the final touch being the alien gemstone he had given Grant, which grants an individual his desires.

However, Grant reveals that he thought the gem was medicine for his cough and swallowed it. Grant begins to levitate, as the Doctor tries getting Grant to calm down, but the boy does the opposite, launching them into the air. They end up on a radio tower, where the Doctor explains that the gem is giving Grant what it thinks he wants: superpowers. Managing to get back to the roof, the Doctor makes Grant promise to not use his new superpowers. Wondering if he'll keep them, Grant is informed that the gemstone might be "expelled" eventually.

Years later, a man awakens to the sound of crying baby. He rushes out of bed and tends to the little girl. He calls the mother, whom works for as a nanny, assuring her that her daughter is safe and sound. As he rocks the baby back to sleep, a red glow comes from within him; he's Grant grown up.

Sometime later, a conference is held at Harmony Shoal, where Mr. Brock is questioned by Lucy Fletcher as where the benefactors for the organization are. Brock jokes that he killed them all and buried them in his backyard. Nardole asks where the little boys' room is, but becomes confused by the American terminology. Brock is approached by Dr. Sim, who tells him something is wrong. He tells Sim to meet him at Midnight.

Come Midnight, Dr. Sim leads Brock to a vault where brains are being held. They are followed by Lucy, who unknown to her, is followed by the Doctor; when she notices him, he tells her to keep listening in. Oddly, he is eating sushi; he comments that bringing a snack is the mark of a pro. Dr. Sim reveals that the brains are alive, and that he is not Dr. Sim, but one of the brains that switched places with him. Brock is locked inside to have his brain replaced with an alien.

The Doctor and Lucy run away, with her revealing her true identity to him; after her shock, the Doctor jokes it's spooky how that happens. He looks at a map showing where Harmony Shoal has set up shop. Nardole arrives, noting that New York is not a capital city. Sim confronts them, with the intent to shoot them. However, the Doctor makes it a stalemate as no-one will believe he shot three people in the back in self-defense. The situation gets stranger as they hear knocking on the window of the 100th floor. Lucy turns around in shock; it's the Ghost, a superhero vigilante.

Popular culture

 * Young Grant Gordon is a comic book fan, and becomes a superhero in their vein. He owns a Superman comic, and has posters on his wall of superheroes including Hulk, Thor, Spider-Man, Batman, Wolverine, Silver Surfer, Superman and the Flash. His duvet depicts Captain America and Iron Man, among others.
 * He also has an The Defenders poster published by Marvel Comics Group. It depicts the cover of issue 109 (July 1982) "Valkyrie's Vengeance".
 * Gordon nicknames the Doctor "Doctor Mysterio"; the name appears to be a mix of the Spider-Man villain Mysterio and the hero Doctor Strange.
 * Grant Gordon's name is alliterative, like Clark Kent, Lois Lane, Lana Lang, and many other Superman characters. Alliteration was even more frequently used by Marvel's Stan Lee when naming superheroes such as Peter Parker, Bruce Banner, and Stephen Strange.
 * To make the point of Superman and Clark Kent being the same, the Doctor draws glasses on Superman. Lois Lane did the same in Superman II. The interior artwork shown is from Superman #7 (July 1987) and #19 (July 1988) by John Byrne.
 * Mr. Brock mentions Miss Shuster and Miss Siegel. This is a reference to the creators of Superman, Joe Shuster and Jerry Siegel.
 * The episode has a Marvel style comic book opening.
 * Below Lucy's apartment, a Joe's Pizza is situated. A pizza parlour of this name featured in 2004's Spider-Man 2, and was where Peter Parker worked.
 * The Harmony Shoal building has a globe on top with the name. This is a reference to the Daily Planet building from Superman, which is also topped with a globe with its name on it.
 * The episode was also heavily influenced by the 1978 film Superman in particular. Both Grant Gordon/The Ghost and Clark Kent/Superman wear glasses to hide their superhero identities, particularly when rescuing a reporter they are close to, and have feelings for, in their everyday life. They then arrange a rooftop interview in which they attempt to reveal their dual identities. Then are also contacted via a specific frequency which only they can hear.
 * The Doctor tells Grant off for leaving the baby unattended, using the words "With great power, comes great responsibility". These words were used by Uncle Ben to Peter Parker, and they later became Spider-Man's mantra.
 * The Ghost tells Lucy "I hope this unpleasant experience hasn't put you off a career in journalism". This is a wonky reference to Christopher Reeve's Superman saying in the 1978 film, "Well, I certainly hope this little incident hasn’t put you off flying, miss. Statistically speaking, it’s still the safest way to travel."
 * In the 1960s Batman TV series, Adam West's caped-crusader would often give very heavy-handed PSA-style speeches to Robin, and seemingly, the audience. This is referenced when the Ghost tells a reporter that every good citizen should "get a smoke detector".
 * When the Doctor accidentally gives Grant a gemstone, which Grant swallows, the Doctor says the gemstone is giving him "what he always wanted". The first Captain Marvel (later known as "Shazam") was actually a child named Billy Batson who can become a superhero. The metafictional influence in The Return of Doctor Mysterio may also be a reference to the Mark Millar comic series Superior in which a young boy literally becomes a popular fictional flying hero.
 * When Grant calls Lucy as the Ghost, the screen is divided, just like in a comic book.

Story notes

 * The name Doctor Mysterio comes from the name in Mexico for Doctor Who, Doctor Misterio (as a literal translation of the title, "Doctor Quien", would make less sense in Spanish than in English), which Steven Moffat and Peter Capaldi encountered when they visited there in the Doctor Who World Tour. Capaldi in particular fell in love with the name, so Moffat decided to use it in an episode title. Capaldi noted that he was quite taken by the deep voice that announced the title on the overdubbed soundtrack, and in fact when the Doctor utters the name in the episode, this is Capaldi impersonating the delivery of the announcer.
 * The read-through for The Return of Doctor Mysterio took place on 31 August 2016, and filming on the episode began on 5 September, wrapping up on 4 October.
 * In fact, the Christmas special was filmed in between blocks 2 (Thin Ice / Knock Knock) and 4 (Oxygen / The Pyramid at the End of the World) of series 10, meaning the first four episodes of the Doctor's adventures with Bill Potts had already been filmed before this one.
 * Matt Lucas is the first comedy writer to play a companion in a television story since James Corden as Craig Owens in Closing Time. The last comedian to play a full-time companion, though, was Catherine Tate as Donna Noble.
 * Daniel Lorente (Teen Grant), Sandra Teles (Reporter), Tanroh Ishida (Operator) and Vaughn Johseph (Soldier) are not credited in Radio Times.
 * The pre-credits sequence is the longest in the history of the franchise, running a little over nine minutes.
 * The previous broadcast story, The Husbands of River Song, was also a Christmas special. This marks the first time two full consecutive television stories have both been broadcast on Christmas Day.
 * This is the first Christmas special since The Snowmen in 2012 to have a coming soon trailer at the end.
 * This story was the third Christmas special to star Peter Capaldi and the first not to feature any Eleventh Doctor companions since The End of Time.
 * Unlike the two previous Christmas specials, the title sequence has no Christmas-themed changes. Matt Lucas is also credited as "And Matt Lucas" before the show's title (similar to Nick Frost in Last Christmas), unlike previous companions whose actor's name immediately followed the Doctor's.
 * Keoki's "Pass It On" plays in the scene where the Doctor catches up with teenaged Grant in high school.
 * One of the things the Doctor and the young Grant discuss is Spider-Man. In Daleks in Manhattan and Evolution of the Daleks, the character of Frank is played by Andrew Garfield who played Spider-Man in The Amazing Spider-Man movies.
 * Several Dioramas were released, the first being The Return of Doctor Mysterio Diorama.
 * This, along with TV: The Keeper of Traken, is the only story in the entire show where the Doctor travels with a male companion throughout, excluding stories such as The Next Doctor or The End of Time where the Doctor was travelling alone and had help from a male character.

Production errors

 * Grant wears glasses even thought he doesn't need them (to see properly or to conceal his identity). His mask as the Ghost covers most of his face, so he wouldn't be recognized out of uniform.

Myths

 * Characters from Class would appear in a crossover. False.
 * Clara Oswald would appear or be referenced in a substantial way. False. Originated from fans interpreting comments made by Peter Capaldi at a June 2016 convention appearance in Washington, DC, that he had "just filmed something" involving Clara as indication of an appearance or reference. Ultimately, this ended up being a reference to his appearance in the Class episode TV: For Tonight We Might Die, which also featured a Clara reference.
 * Pearl Mackie would make her first appearance. False, the Series 10 trailer notwithstanding.
 * Alex Kingston would appear as River Song. False, though River is referenced.
