Let's Kill Hitler (TV story)

Let's Kill Hitler was the eighth episode in the sixth series of Doctor Who and the first episode in the Autumn half. As did A Good Man Goes to War, it revealed much about River Song's origins. It's also the first time that the Doctor has died and been umnble to save himself through regeneration.

Synopsis
In the desperate search for Melody Pond, the TARDIS crashes in 1930s Berlin, bringing the Doctor face to face with the greatest war criminal in the Universe - and Hitler. as well. The Doctor must teach his adversaries that time travel has responsibilities – and in so doing, learns a harsh lesson in the cruelest warfare of all.

Plot
Amy and Rory drive through a corn field with Amy giving directions badly. They find the Doctor standing by the TARDIS, holding a paper; he asks "really?" An overhead veiw shows that Amy and Rory have made crop circle spelling out "Doctor" because he has not been asnwering their phone calls. The Doctor asks Rory for permission and hugs Amy, reminding her that Melody grows up to be River Song, which means that he will find her; he hasn't yet. Rory spots a line in the picture they did not create as they wonder what caused it. A Corvette that nearly runs over the Doctor pulls into the circle, revealing it caused the line. Amy and Rory's best friend Mels steps out. She knows of the TARDIS and the Doctor because she grew up with Amy's stories about him. About to be arrested, she points a gun at the Doctor and orders him to take her away. On a whim, she decides that they should kill Hitler as the TARDIS is a time machine.

Flashback: Mels is a school troublemaker. She gets in more trouble than anyone except boys. She insults teachers, continually references the Doctor and even steals a bus. Back in the TARDIS, she shoots the console and the TARDIS spins madly out of control with the Doctor yelling at her for doing so.

In 1938 Berlin, a janitor watches a Nazi officer. In a futuristic control room, the crew discuss copying the officer. The janitor confronts the officer. In the control room, a woman complains that when they relied on the computer, it "made Rasputin green". She goes to 'the top level', where an electronic voice politely threatens her for not being authorized; the device she has on her wrist has turned red. Hitting it, she managed to make it green, allowing her to pass. She looks through a viewport, which is the eye of the janitor, actually a highly advanced ship, the Teselecta. She relays colour codes to the control room. The janitor becomes the officer's double and beams him aboard with a miniaturisation ray. The captain wonders who he is and upon learning the answer, decides to let the ship's "antibodies" kill him for his crimes. The ship then walks into Adolf Hitler's office, where the ship announces that the room has been sound-screened and that he wil be punished for his myriad crimes. Just as it paralyzes him with a beam, a crewman says it is "too early" in his time stream.

Before that is explained, the TARDIS crashes into Hitler's office, knocking over the Teselecta. The TARDIS occupants stagger out in a cloud of smoke caused by Mels shot into the time rotor. The Doctor applogizes for causing a mess until Hitler picks himself up and they recognise him. Hitler thanks the dumbfounded travellers for saving him and asks what the TARDIS is. The Doctor advances on him, saying it's a police box and "The British are coming!" The Teselecta picks itself up and a paniky Hitler fires at it. Rory punches Hitler, knocking him downand taking his gun. On the Doctor;s orders, Rory puts him in a cupboard. Mels then weakly says Hitler was a poor shot and starts dying; the Teselecta has had the ship faint to do recon. Mels tells the Doctor that she's wanted to marry him; he promises to do so when he meets her parents. She then says that they are right there, so he should just ask. The Doctor immediately realises that Mels is Melody Pond and informs Amy that she has been with them their entire lives. Melody then regenerates into River Song. The Teselecta scans the scene. Here is the most infamous malefactor in history, whose crimes dwarf Hitler's: Melody Pond.

Melody is amazed by the change to her skin tone and begins doing random things as she gets accustomed to her new body. The Doctor, Amy and Rory discuss that this is River Song right at the beginning; she doesn't even know who she is yet. Melody overhears them talking about River and is told it's a spoiler they can't tell her. Calming down, Melody then tries to kill the Doctor several ways, but he thwarts her. Melody tells the Doctor that she didn't kill him in the field becaue they just met; she may be a psychopath,. but she's not rude. Amy wonders why Melody is a psychopath and the Doctor explains that she's what the fight on Demons Run was about; creating his personal killer. Melody kisses him and warns her parents not to follow her out the window. She then informs the Doctor her lipstick was poisonous. The dying Doctor orders Amy and Rory to catch her. The pair watch her knock out soldiers with her regenerative energy, steal their guns and flee on a motorcycle, saying that she's going shopping.

Amy and Rory follow on a second motorbike and the Teselecta on a third. The Doctor reels into the TARDIS. He activates the voice interface in the form of a hologram of the Doctor. He asks for someone he likes instead. It offers images of Rose Tyler, Martha Jones, and Donna Noble, all of whom induce wails of guilt. Finally, it offers the young Amelia Pond, whom tells the Dotor that the poison comes from the Judas Tree and prevents regeneration from occuring. The Doctor tries to get "Amelia" to help him gather his strength but it insists it is not Amelia, just a hologram. He collapses, whimpering for help. He hears "Fish fingers and custard" and drags himself to the console to confront the Teselecta.

Elsewhere, Melody steals all the clothes at machine gunpoint from restaurant diners and works on her ensemble. Amy and Rory arrive outside the restaurant, followed by the Teselecta, now disguised as Amy. Inside, Melody is trying on outfits when Teselecta-Amy walks in and accuses her of killing the Doctor. Amy and Rory wake inside the Teselecta. One of the crew saves them from the antibodies. Outside, the Teselecta tells Melody that she murdered the Doctor on the orders of the Silence, an academy of the Question. Melody tells it that she really doesn't know as it's all a blur to her. The Teselecta then captures Melody in the same light it used on Hitler.

The Doctor arrives at the restaurant in evening clothes. The Teselecta explains that as a form of justice, they visit war criminals at the ends of their lives, and "give them hell", agonising pain, while the timeline continues. Pursuing this mission, the ship captures Melody and tortures her. The Doctor orders it to stop; Melody is frozen in place. The Doctor asks who wants him dead. Amy persuades the Teselecta captain to tell him. It says the Silence are behind the plot to kill him; they are not a species but a religious cult who believe "silence will fall" when the oldest question in the Universe is asked; it is hidden in plain sight, but it does not know what that question is. The Doctor's kidneys then go out due to the poison and he begins crying in agony.

The Teselecta resumes torturing Melody as the Doctor tells Amy to save her daughter. Remembering the security clearance devices are what keeing the antibodies from attacking the crew, Amy uses the sonic screwdriver to turn them off. The antibodies attack the crew and they teleport to safety, leaving Amy and Rory in the Teselecta. Amy uses a microphone to call to the Doctor for help. Despite being in unimaginable pain, the Doctor picks himself up and tries crawling over to the TARDIS. Melody watches this and is amazed that he still cares about her parents. The Doctor lacks the strength to continue and begs Melody by the name "River" to help him. Jealous of River being the person the Doctor keeps calling out to, Melody demands that the Doctor tell her who she is. Stressed, the Doctor begins crying, asking Melody to just help.

Inside the Teselecta, Amy and Rory have just been cornered by the antibodies as the TARDIS materilises around them. Overjoyed, they go to thank the Doctor, only to find Melody walk out from behind the time rotor. She flew the TARDIS; it taught her how. The trio go to the Doctor, but he says there is no way for him to survive. He asks to speak to Melody. He asks her to find River Song, whispers something in her ear and dies. Melody asks who "River Song" is and Amy orders the Teselecta to show them. To Melody's shock, it shifts into her. Having learned that she is the Doctor's "beloved friend", Melody asks her parents if the Doctor is "worth it" as her hands begin glowing. They don't understand her question, but agree he is. Melody places her hands on the Doctor, reviving him. Melody greets the Doctor and kisses him.

Melody later wakes up in a hospital to learn from Amy that she lost all her remaining regenerations, bringing the Doctor back to life as the cost. However, Melody says that the Doctor said noone could save him, meaning he was lying. The Doctor reminds her that it's Rule 1 with him and she goes back to sleep. A nurse tells them that she will be better after some rest. The Doctor leaves a fresh TARDIS-shaped diary on Melody's bedside, starting her side of their relationship.

In the TARDIS, Amy and Rory wonder if it's okay just to leave Melody there. The Doctor tells them that they have to as they have foreknowledge on her future as he looks at the montior, which shows he has discovered the day of his death. Amy wonders what he is looking at, but the Doctor turns off the information, explaining it was just boring information he downloaded from the Teselecta. Rory then wonders if all the brainwashing the Silence did to Melody is gone now as the future River is imprisoned for murder. The Doctor explains Melody went through with her programming, then overcame it and brought him back to life - "as far as first dates go. I'd say that was mixed signals". Amy wonders if they'll see Melody again and the Doctor assures her that they will. When Amy questions how, the Doctor points out that she should know how by now.

Some time later, in 5123, Melody, now going by her alias River Song, applies at the Luna University for a degree in Archaelogy. When questioned as to why she is interested in getting a degree in archaelogy, River answers that she is "looking for a good man", holding her diary.

 * Rule 27: Never knowingly be serious.
 * Rule 408: Time is not the boss of you.

The Doctor's items

 * The Doctor uses a sonic cane.

Companions

 * Rose Tyler, Martha Jones and Donna Noble all appear as projections for the TARDIS voice interface, after the Doctor rejects a projection of himself and asks for "someone he likes." He rejects all three projections because of increasingly strong feelings of guilt. Finally, the TARDIS settles on a projection of the child Amelia Pond.

Foods and beverages

 * The TARDIS's projection of Amelia mentions fish fingers and custard.

Religion

 * The Silence are not a species, but a religious organisation of sorts.

TARDISes

 * The temporal grace in the TARDIS, which supposedly prevents weapons fire, is said by the Doctor to be a "clever lie".

Story notes

 * This is the first episode of the Autumn half of the series. The Spring half concluded on 4 June with A Good Man Goes to War.
 * This is the second time in the Eleventh Doctor era that companions of the previous two Doctors have been mentioned or seen in a proper episode since The End of Time; Rose Tyler was previously seen (briefly) in The Lodger.
 * The images of all the former companions are taken from publicity shots. The projections of Rose and Donna are publicity images from Series 4. The projection of Martha is from a publicity image for Series 3.
 * The Doctor makes the "Doctor Who?" running joke.
 * The car Mels steals is a Chevrolet Corvette, third generation (68-82).
 * The layout of the Teselecta's bridge is deliberately reminiscent of that of the Enterprise and other Federation starships from the television series Star Trek.
 * The TARDIS's voice interface tells the Doctor he will be dead in thirty-two minutes. Coincidentally in-universe, the invitation the future Doctor sent out to everyone in The Impossible Astronaut, to meet at Lake Silencio for the Doctor's death was for 4:30pm and according to the biographical information the Doctor is shot during regeneration and killed at 5:02pm.
 * The hand gun that Mels pulls out is an IMI Jericho 941.
 * Harriet mentions the Teselecta having transformed into Rasputin. Tom Baker played Rasputin in the movie Nicholas and Alexandra.
 * In Mels' first scene in the episode, her face cannot be seen due to the sun's glare behind her. She moves her body to block the sun and her face is shown, much like the first scene of River in The Impossible Astronaut.
 * Melody Pond says, "Hello Benjamin" to the Doctor. The Doctor previously claimed Scotland Yard's code name for her was Mrs Robinson. (DW: The Impossible Astronaut) Both reference the movie The Graduate where a younger man, Benjamin, is seduced by an older woman, Mrs Robinson.
 * On the Leadworth Chronicle, a story with the headline "BACK OF THE NECK" can be seen. This is a reference to the weakness of the Sontarans. (DW: The Poison Sky)

Ratings

 * UK Overnight: 6.2 million
 * UK Final: 8.1 million

Myths

 * The Daily Mirror reported that Rose Tyler, Martha Jones and Donna Noble will appear in this episode. This was half true as images of all three of them appeared but these were avatars for a TARDIS interface, rather than the characters themselves.

Filming locations

 * Swansea, Wales.

Production errors

 * When the Doctor and the TARDIS make their first appearance, they point right, towards Amy and Rory's car. However, when the camera zooms out, the Doctor and TARDIS are looking down, and not towards Amy and Rory. This also causes an error when Mels drives through the word Doctor.
 * Hitler shoots Mel in the stomach, but there is no blood or puncture hole on her dress.
 * When Rory asks "How can they just disappear?" two antibodies appear, but in the next shot there are three.
 * When the poisoned Doctor is in the TARDIS he has one of his arms up on the bannister; in the next shot he has it by his side.

Continuity

 * Images of Rose Tyler, Martha Jones, Donna Temple-Noble are seen. (DW: Rose, The Runaway Bride, Smith and Jones) The Doctor feels guilty for what he did to Rose, feels "more guilt" for what he did to Martha and "even more guilt" over Donna.
 * The Doctor mentions "the Vampires in Venice". (DW: The Vampires of Venice)
 * The Doctor speaks about River at Demon's Run. (DW: A Good Man Goes to War)
 * Rory punches two people in the jaw to knock them to the ground. Rory (as an Auton) previously did this to the Doctor. (DW: The Big Bang)
 * River begins studying archaeology. (DW: Silence in the Library)
 * The TARDIS's projection of Amelia mentions fish fingers and custard. (DW: The Eleventh Hour)
 * Melody mentions regenerating into the toddler form of Mels in New York. (DW: Day of the Moon)
 * The Doctor switches Melody's gun for a banana, similar to what he did to Jack Harkness in The Doctor Dances.
 * River reveals she learned how to pilot the TARDIS from the TARDIS herself. (DW: The Time of Angels)
 * The Doctor tells Melody "Rule one: The Doctor lies." (DW: The Big Bang) One of the first things the Doctor hears River say is "I'm always lying." (DW: Silence in the Library)
 * River's diary (DW: Silence in the Library) makes its first chronological appearance in this episode, a gift from the Doctor himself.
 * The Teselecta data console states The Doctor's TARDIS is a Type 40 Mk 3 TT Capsule.
 * The Teselecta crew mentions something in "Kennedy"'s timeline is not a fixed point in time. While this is probably a reference to the assassination of American President John F. Kennedy (an event witnessed by the Ninth Doctor), it could refer to the death of his brother, Senator Robert F. Kennedy, or another event involving a member of the Kennedy family.
 * It is mentioned twice that River uses her "remaining" regenerations to revive the Doctor, implying that she has a fixed amount. It is unclear whether the Doctor gained that many new regenerations or if he still has only two remaining. Transferring future regenerations from one regeneration-capable individual to another has been offered before. (DW: Mawdryn Undead, Doctor Who (1996), The Ultimate Foe)
 * River has previously used a type of lipstick to her advantage. (DW: The Time of Angels, The Big Bang) This time, she uses a poisonous version.
 * River was able to completely recover after being shot several times by German soldiers. This was due to her still being within the first fifteen hours of her regeneration. The Tenth Doctor recovered from a severed hand while fighting a Sycorax under comparable circumstances. (DW: The Christmas Invasion)
 * When first detecting there are life forms inside the Teselecta, the Doctor wonders if it is bigger on the inside.
 * The TARDIS was previously able to materialise inside a smaller object containing miniaturised life forms in a compression field. (DW: Carnival of Monsters)
 * Mels says "See you later, Time Boy" during a flashback. Donna Noble called the Doctor "Time Boy". (DW: Journey's End)
 * The Doctor says "Spoilers" when Melody asked who River was, a word frequently used by River herself later. (DW: Silence in the Library, et al)
 * The Doctor previously said that "Time is not the boss of me." (DW: The Time of Angels)
 * Amy had a picture of herself and (apparently) Mels on a table in her bedroom. (DW: Flesh and Stone)

Motion comic scene
The original BBC America broadcast of the episode includes an extra scene sponsored by AT&T, which aired during a commercial break. Written by Steven Moffat, the scene is an extension of the motorcycle chase sequence with Rory and Amy. It is presented in animation/motion comic format. Lasting sixty seconds and produced by Double Barrel Motion Labs, the scene was originally promoted as being intended for inclusion in the later Series 6 DVD/Blu-ray releases, but as of early November 2011, this appears not to be the case. The ad/motion comic was only seen in America.
