The War Machines (TV story)

"We can't let that thing loose over London!"

- Sir Charles Summer

The War Machines was the tenth and final story of Season 3. There were several companion cast changes in this story - Dodo Chaplet, played by Jackie Lane, left, while Polly Wright and Ben Jackson, played by Anneke Wills and Michael Craze, joined.

Synopsis
The TARDIS arrives in London in 1966 and the Doctor and Dodo visit the Post Office Tower. There they meet Professor Brett, whose revolutionary new computer WOTAN (Will Operating Thought ANalogue) can actually think for itself and is shortly to be linked up to other major computers around the world - a project overseen by civil servant Sir Charles Summer.

It transpires however that WOTAN considers that humans are inferior to machines and should therefore be ruled by them. Exerting a hypnotic influence, it arranges the construction of War Machines - heavily-armed, self-contained mobile computers - with which to take over the world.

These prove more than a match for troops, but by establishing a magnetic force field the Doctor is able to capture one of them, which he then reprograms to destroy WOTAN. Dodo, now back in her own time, decides to remain on Earth. The Doctor enters the TARDIS alone, but Brett's secretary Polly and her merchant seaman friend Ben Jackson follow him inside just before it dematerialises.

Episode 1
The Doctor and Dodo arrive back in London, the Doctor taking care to hang an "out of Order" sign on the TARDIS door to keep away any unwanted police. Immediately the Doctor senses something isn't quite right about the newly completed Post Office Tower and takes Dodo to investigate.

The Doctor, posing as a computer specialist is escorted to the top of the tower by Major Green where he meets Professor Brett and the professor's life's work, WOTAN. Also in the room is Professor Brett's secretary. Polly. The Professor proceeds to explain how WOTAN is the most advanced computer ever made and how it will soon be linked to other computers around the world to create a central intelligence. The Doctor challenges WOTAN to give him the square root of a large number, which it does flawlessly. Dodo, then hoping to stump the computer asks it what the word TARDIS means which it also answers correctly, much to the Doctor's consternation. Dodo then pauses as she complains about a slight buzzing in the ears. Polly, looking after Dodo, invites her to go to a dance club called "The Inferno".

Arriving at the club, Kitty, the bartender and Polly's friend, tells them that a sailor that Polly met the previous week has come into the bar every night since and sat at the end of the bar drinking and depressed. Just then, the sailor enters and Kitty asks Polly to try and cheer him up. Polly and Dodo make a valiant attempt, but finally decide to leave him to himself. But shortly after, when Polly is being harassed by another patron, Flash, the sailor jumps to her defense, starting, and quickly ending, a minor bar fight. Dodo is then able to get the sailor's name, Ben Jackson. Soon after a taxi pulls up to The Royal Scientific Club, location of a press conference about WOTAN. The assembled reporters learn that on the following Monday, July 16th, all other computers around the world will come under the control of WOTAN in an event called Computer Day or C-Day. After a number of questions from reporters, Sir Charles Summer, head of The Royal Scientific Club, tells those gathered that WOTAN actually thinks and has no political allegiances or any reason to lie or hide the truth. Professor Brett, who is oddly absent, is sent for by Sir Summers.

Professor Brett, caught on the phone in his office, finally prepares to leave for the press conference when he calls in Major Green. The Professor informs the Major, that he's had the feeling all day that someone has been watching and listening to the goings on in the area. The Major assures the Professor that the building, and especially the area WOTAN is in, is secure. After Major Green leaves, Professor Brett prepares to go, but hears a strange buzzing coming from WOTAN. Stopping momentarily, he is overcome by the buzzing, and though he attempts to fight off the sound, he quickly comes under the mental control of WOTAN.

Back at the Inferno, Dodo tells Polly and Ben that she has a bit of a headache, but tells them that she is really fine. When they go off to dance though, Dodo's face shows that something isn't right.

Just as Sir Charles prepares to dismiss the gathered reporters, Professor Brett finally arrives. While he refuses any comment to the media, he takes Professor Krimpton aside on urgent business. Sir Charles introduces himself to the Doctor who inquires about Professor Krimpton. Sir Charles, remarking the Krimpton is their foremost electronic expert, begins to worry that something is wrong with WOTAN, and leaves to find out. The Doctor seems to have other ideas.

Back with WOTAN, Major Green enters the room on his rounds and quickly comes under the control of the machine. He then calls the Inferno and places WOTAN on the phone and it also takes control of Dodo, who then leaves. Shortly after, Professor Brett returns to Wotan with Professor Krimpton and explains to him that WOTAN has come to the concussion that humans cannot develop the world any further and that it will take control and humans will be the servants. When Professor Krimpton attempts to leave, he is stopped by Major Green and becomes the fourth to fall under WOTAN's control.

At the Inferno, Polly and Ben are looking for Dodo when the Doctor arrives. Polly tells the Doctor the Dodo had received a call about half an hour before and then seems to have left. Dodo then arrives in Professor Brett's office and is instructed to bring "Doctor Who" so that he can be brought under the control of WOTAN.

Episode 2
As Dodo leaves to find the Doctor, WOTAN issues his directions to Professor Brett, Major Green, and Professor Krimpton. London will be taken over first followed by Washington and Moscow. A skilled labor force, obtained through telephone based thought control, will be gathered in a number of points in London to construct "the machines", mobile computers. Green will determine the locations, Brett will oversee construction, and Klimpton will prepare their programing. Prior to programming preparation, though, Klimpton is instructed to assist with obtaining "Doctor Who". The Doctor remains at the Inferno until close. Polly prepares to begin calling hospitals when Dodo walks back in claiming that the call was from some old friends and that she was just around the corner. The Doctor questions Dodo's story, but doesn't continue to press when she says that it was all a long story. As the four leave the club, Ben and Polly go to flag down a taxi for the Doctor and Dodo. Dodo, seeing fellow conspirators waiting in the shadows to grab the Doctor, begins to guide him a little way down the street when Ben and Polly arrive with the Taxi. Polly decides to tag along with the Doctor and Dodo to visit with Sir Charles. A homeless man, who had go out of the Doctor's cab, stops Ben to ask for a little money for food and tells Ben that he is planning on sleeping in an empty warehouse nearby.

In that no-longer empty warehouse is Professor Brett, handing out blueprints for the machines that the laborers are constructing. The homeless man, upon entering the warehouse, sees the activity and overhears Professor Brett's directions. Quickly an alarm comes from a nearby computer and Brett sends a number of the laborers to find the intruder. The homeless man attempts to leave but is surrounded and quickly killed.

The next morning the Doctor is visiting with Sir Charles and looking at the paper when he sees the picture of the homeless man in an article about his murder. While Sir Charles is only mildly interested he brings to the Doctor an issue of two well respected scientists who work for the Royal Scientific Club who both sent letters of resignation that morning and since cannot seem to be found. Shortly thereafter Polly enters informing Sir Charles that Major Green had called her and sent her to assist Sir Charles since Professor Brett did not need her for the day and because Sir Charles' secretary was ill. Sir Charles, surprised that Major Green knew of his secretary's absence accepts Polly's assistance for the day. As Polly heads out of the room Dodo walks in. When she hears Sir Charles' concern about the resignation of two of his computer scientists, Dodo presses the Doctor about returning to visit Professor Brett. The Doctor, not wanting to drop in unannounced decides to call Brett's office.

Professors Brett and Klimpton are working in the office when the phone rings. Picking it up, Brett realizes it is the Doctor and Klimpton patches the phone through to WOTAN.

The Doctor, still in Sir Charles' office quickly realizes what is happening and pulls the phone from his ear, though with some significant trouble. Weak, Dodo and Sir Charles assist the Doctor to a nearby chair and Sir Charles leaves to get some water. Dodo, believing that the Doctor is now under WOTAN's control, begins to give the Doctor WOTAN's instructions. The Doctor quickly shakes off the effect of the call, but is still confused as to what happened. As Polly and Sir Charles return with water, Dodo remarks that the Doctor did not receive any instructions. When Polly asks what happened the Doctor realizes that the problem was not with the phone, but that something in Professor Brett's office, specifically WOTAN, had attempted to take control of him and had control of Dodo. The Doctor uses his ring to aid in the hypnotism of Dodo to break her programming. The Doctor informs Sir Charles and Polly that Dodo will sleep for about 48 hours and afterward need quiet and rest. Sir Charles agrees to have Dodo taken to his country estate where his wife will care for her and turns to ask Polly to make arrangements, but she has already left the room. The Doctor then begins to wonder where the "strategic points in London" that Dodo mentioned might be.

In a customs shed near the airport and in a large factory, we see parts for Wotan's machines being unloaded and constructed. Back in the warehouse we see one of the machines powered on and Major Green arrives to test the machines destructive capabilities, testing, of course, on one of the laborers.

At the Post Office Tower in Professor Brett's office, WOTAN inquires to the location of "Doctor Who". Moments later Polly enters to make sure that Professor Brett is alright, but quickly she realizes something is very wrong.

At Sir Charles' office Ben arrives looking for Polly to take her to lunch. When Ben says he can't find Polly, the Doctor is concerned about Polly. Mentioning the homeless man in the paper, the Doctor asks be to investigate the area around the club to see if they can find any information about what is going on.

Ben, looking around the Inferno's building, overhears Major Green's testing of WOTAN's machine and heads inside to find out what's going on. Ben watches the machine destroy a table with good results, look around the room with some problems, and then move around a room and destroy some crates that are in its way. As it comes around another corner Ben is caught directly in the machine's line of sight.

Episode 3
Ben, backed up against a wall of boxes, ducks behind another nearby box and makes his way to a door with the machine sounding an alert. Major Green calls the laborers to search for the unknown trespasser just a Ben ducks through the door... and finds Polly in the entryway. Ben warns Polly to get away and tells her he must inform the Doctor what he's seen. Polly asks him what he saw, and he explains, but, as he moves toward the door to leave Polly locks him in and he is captured.

Four hours later a Sir Charles' office, the Doctor has grown worried about Ben. Sir Charles tells the Doctor that rumors shouldn't postpone C-Day and that they should allow the Police to look into them, but the Doctor fears that the police might only drive the threat further underground.

In the warehouse, Major Green tells Ben of the coming "mechanized evolution" and prepare to have him destroyed. Polly enters with directions from WOTAN that more labor is needed and that Ben is to be kept alive as long as he is useful. When Ben goes to thank Polly, she tells him he must work towards the victory of the War Machines.

In Professor Brett's office, he and Professor Klimpton take note of the completion time of noon on the following day. The purpose and function of the war machines are also detailed.

The war machine in the warehouse has almost completed all tests and the laborers are preparing armaments for the war machines, but they are tiring. Ben, working in a back room of the warehouse, attemps to talk Polly into resting when he notices that the guard on the door is gone. He goes to investigate, but as he prepares to run he locks eyes with Polly. Instead of sounding an alarm, Polly simply goes back to moving crates. After prying the locks from the entryway door, Ben finally escapes the warehouse.

As the Doctor prepares to go in search of Ben, Sir Charles' doorbell rings and Ben stumbles in. He reports that Polly is in a warehouse and being controlled and that there is a killer machine there as well.

Major Green confronts Polly concerning Ben's whereabouts. She informs Green that Ben has escaped, but she cannot answer why she didn't raise an alarm and then becomes confused. As the control over her breaks down, Major Green informs the laborers that Polly must be sent back to WOTAN to be punished.

Sir Charles refuses to believe Ben's story, and Ben is anxious to get moving and take action against the machine. As Sir Charles prepares to contact the police to raid the warehouse, the Doctor points out that something bigger is going on and that, from what Ben has told him, it sounds as if there are more machines being built around London. When the Doctor recommends striking at WOTAN, Sir Charles refuses and says there is nothing to connect this machine to Professor Brett, even though Polly is one of those under control. The Doctor and Ben, knowing they have riled Sir Charles depart and Sir Charles contacts the authorities and decides to head toward the warehouse himself.

Based on Sir Charles' report, Army soldiers are mobilized to the neighborhood around the warehouse. They find considerable electrical and radio activity coming from the warehouse and surround it. Sir Charles informs the commanding officer of what he knows, and orange patrol is sent to enter the warehouse. Interference in the radio signals tips off Major Green that something is happening and he alerts the laborers. As Orange Patrol confronts the war machine, Green gives the order to attack and the laborers and the war machine assault the patrol. Orange patrol quickly finds it's weapons are useless against the war machine and thus must retreat. Just as the remaining members of orange patrol exit the warehouse, the Doctor and Ben join Sir Charles and inquire about what is happening. As orange patrol rounds the corner toward the main army forces, the war machine exits the warehouse in pursuit. The leader of orange patrol reports that the machine nearly wiped them out as it comes around the corner into view. Sir Charles, assuming someone is inside the tank-like machine, attempts to call the operator to stand down. As the army realizes that their guns are somehow being jammed, the commanding officers informs Sir Charles that the area will have to be evacuated. As everyone retreats, the Doctor stands his ground and even walks a bit toward the machine as the light from the war machine's eye falls across his face.

Episode 4
As the war machine approaches Ben attempts to pull the Doctor to safety, but the Doctor stands his ground and the war machine moves around him and comes to a halt with it's top mount radar dish ceasing to function.

In a local pub, the news reports that the war machine has been stopped, but that further attacks can be expected over the next day.

The Doctor, examining the war machine, finds that the programming and test had not completed and that the computer had failed. Sir Charles notes to the Minister of Defense that, if the programming and test had been completed, it would have been nearly unstoppable. The Minister remarks that the other war machines must be found and destroyed before they are operational.

Elsewhere in London, construction of the second war machine has been completed and testing begins.

The Doctor is investigating the inoperable war machine when Ben arrives having been unable to find Polly. When the Doctor hands his cloak to Ben, the TARDIS key falls from the pocket and Ben picks it up. As he goes to hand the key back to the Doctor, the Minister of Defense approaches asking for a status report from the Doctor. The Doctor has determined that there were 11 more units in the 20 to 30 miles around London, all set to begin an attack at noon.

Testing of the second war machine continues, but as the tester walks in front of the war machine he is accidentally killed by a blast from the machine. At the tower, Professor Brett notes that contact with the second war machine has broken down and Professor Klimpton goes to correct the programming that is at fault.

At the Army's operating headquarters one of the survivors from the warehouse is brought in for questioning. As he passes, the Doctor realizes it is Major Green and follows so that he may ask a few questions of the man. Major Green, disoriented and confused, doesn't recognize the Doctor or the war machine that he built. While Sir Charles want's to raid the Post Office Tower and retrieve Professor Brett, the Doctor berates Sir Charles' "strong arm" methods and the Minister seems to agree as he turns to the Doctor for guidance.

Meanwhile, a man in a telephone booth contacts the police to report that another of the war machines is one the streets of London. While on the phone, the war machine spots him and kills him. Over the radio a warning goes out to the citizens of London to stay off the streets and not confront the machines.

Ben, still at the Army operating headquarters, is still worried about Polly's whereabouts. The Doctor tells Ben that if all he worries about is one person then nothing shall ever get done, but Ben feels he owes it to Polly since he feels she saved his life.

As the second war machine approaches the Battersea Power Station, Sir Charles goes to the Doctor and the Minister to find out if they have any other ideas. The Doctor wants to capture the machine by using electro-magnetics to paralyze the machine.

Back in Professor Brett's office, Polly enters and requests to be judged by WOTAN for allowing Ben to escape. Professor Brett informs her that she will be judged later because her assistance is currently needed.

Sir Charles assists the Doctor in obtaining the necessary equipment for the Doctor's Magnetic Field and the Minister of Defense assists in closing off roads to funnel the war machine to the optimal location to spring the trap.

Sir Charles, Ben, and the Doctor discuss the Doctor's plan, which requires moving behind the war machine to connecting a final cable to spring the trap. While the Doctor plans to do it himself, Ben feels that a younger man should take the risk. As the machine approaches, Ben takes up his position preparing to run and connect the cable. After hesitating the war machine moves into the trap area, Ben connects the cable, and the switch is thrown. While the war machine isn't shut down by the magnetic field, it does allow the Doctor to get close enough to shut the machine down manually.

Elsewhere, questions are going out around the world wondering if the attacks are limited to London or if the whole world is at risk.

Finally, the Doctor returns to the Minister and Sir Charles to let them know that he has reprogrammed the machine and that he is ready to send it to complete its new orders. As Ben flips a switch, the war machine hums to life and moves out of the Army operating headquarters headed to the Post Office Tower. Ben, still concerned about Polly and fearing that she returned to the tower, rushes off in hopes of arriving before the war machine and rescuing Polly.

In the Minister's car, the Doctor explains that, should everything go as planned with his reprogrammed war machine, WOTAN should be deactivated and all those under hypnosis should be released.

It is 11:49 AM and in Professors Brett's office he and Klipton are preparing to release the 10 remaining war machines. Minutes later, as the war machine arrives at the base of the tower, Ben arrives in the hall outside Professor Brett's office and sees Polly working at the computer. He rushes in and, pushing past Professor Brett, grabs Polly and drags her out of the office and down the hall, just as the war machine exits the elevator. Klimpton attempts to get close enough to the war machine to shut it down, but is killed in the process. The war machine fires repeatedly into WOTAN and finally destroys it. Professor Brett, grabbing his head in pain, finally comes to his senses, though he has no memory of what happened. As the Doctor, Sir Charles and the Minister exit the elevator, they find the office filled with smoke and a charred WOTAN. As Professor Brett asks what happened, Sir Charles directs him to ask the Doctor... who is no longer there.

Later, the Doctor is standing outside the TARDIS, with the out of order sign still on the door, waiting for someone. As he begins to turn and enter the ship, Polly and Ben run across the street to greet him. Polly tells him that Dodo feels much better, she wants to stay in London and that she send her love. The Doctor, surprised and seeming a little hurt, thanks Polly and Ben for their help and send them on there way. Down the street they watch as the Doctor unlocks the Police Box and enters. When Polly mentions the key, Ben remembers that he still needs to return the one he picked up when it fell from the Doctor's cloak. They run back to return the key, and when he doesn't answer, Polly unlocks the door and enters... and the TARDIS dematerializes.

Story Notes

 * This story had the working title of The Computers.
 * Although Polly was never given an on-screen surname, "Wright" was used in an audition piece for the character at the time. It has since been adopted into various spin-off novels.
 * WOTAN is pronounced with a soft V as VOTAN by many of the characters.
 * This is the Doctor's first return to 20th century London since a brief interlude at the end of "Bell of Doom".
 * The Doctor is particularly ruthless in this story, sending a War Machine to destroy WOTAN when he knows that Brett and Krimpton (and most likely Polly too) are with WOTAN, and are very likely to get killed (as Krimpton does). He does this despite the fact that all three are not acting for themsleves, but are under WOTAN's control, so they have no choice about being there, nor any impulse to escape.
 * As was common in mid-late 1960s Doctor Who, this serial employs interstitial titling for the serial name, episode number and writing credit. For episodes 2 and 3, the titling is unusually placed at the end of a short teaser sequence. For the first and last episodes, the sequence occupies a more usual position immediately after the main titles.
 * Due to budgetary constraints, this story had no original incidental music. (BBC DVD: The War Machines)

Ratings

 * Episode 1 - 5.4 million viewers
 * Episode 2 - 4.7 million viewers
 * Episode 3 - 5.3 million viewers
 * Episode 4 - 5.5 million viewers

Myths

 * A fan myth alleges that Pat Dunlop contributed to the writing of the televised version of the story. In fact, though, Dunlop was the writer originally commissioned to turn Kit Pedler's story idea into script form but had to pull out due to a clash of commitments with another BBC series, United! Ian Stuart Black used none of Dunlop's work when he took over.

Discontinuity, Plot Holes, Errors

 * This is the story in which the Doctor is infamously referred to as "Doctor Who" by WOTAN. This is the only time on television that the Doctor is directly called this. WOTAN perhaps refers to the Doctor in this way due to not knowing who he is. The Doctor may have given a false name at some point.
 * The end of episode 2 does not match with the start of episode 3: The War Machine advances at Ben for a while in episode 2, but in episode 3 Ben has quickly moved behind some crates to avoid being seen. However, most of the serial was junked by the BBC, and as a result, the DVD version is a restored patchwork of the serial, from copies held by the various worldwide TV stations it was sent to. Most of the overseas episodes had some censor cuts, and as a result, a fraction of some of the episodes were lost, and covered by existing footage to match the audio for the DVD release. This may account for the discrepancy.
 * Why does WOTAN stamp a big "W" on the boxes containing the bits of war machine? Isn't it a bit of a giveaway?
 * In Episode 3, the War Machine that is ordered to kill the worker misses him completely, but the bloke obligingly drops dead anyway.
 * Why do Ben and Polly go into the TARDIS at the end? If they think it's just a police box then surely they would think that they couldn't all fit inside.
 * It seems strange that WOTAN can divine the meaning of "TARDIS". Possibly he didn't work it out using his intellect. He might have already known somehow. Though that "explanation" would just answer one mystery with another. Or: WOTAN can read minds as part of the process of influencing them. Dodo is shown to be influenced by WOTAN almost immediately she sees it, so it could have read the definition in her mind. Also, WOTAN can sense the Doctor's "special" mind (hence WOTAN's determination to recruit him), so WOTAN might have got the definition from the Doctor. 
 * The man giving the presentation contradicts himself saying WOTAN is controlled by no one but goes on to say the professor and his team have it well under control.

Continuity

 * The press briefing in Episode 1 states that C-Day will be on Monday, July 16th.
 * Episode 1 occurs 4 days before C-Day on Thursday, July 12th.
 * Since the Post Office Tower is complete, that sets the time frame for this story at some point after October 1965 when it was officially opened. The next "Monday, July 16th" after 1965 occurs in 1973, thus setting this story no earlier than 1973.
 * The press briefing in Episode 1 also shows a chart naming the computers that will come under Wotan's control. While 6 are not clearly seen, those that can be made out are WOOMERA (rocket testing range in Australia), Cape Kennedy (now known as Cape Canaveral), Parliament, ELDO, TELSTAR (early communication satellite), White House, EFTA (European Free Trade Association), RN (Royal Navy), RAF (Royal Air Force).
 * The appearance and function of the War Machines is mentioned briefly in EDA: EarthWorld.
 * Dodo's life following this story is explored in MA: Who Killed Kennedy, which also explains how the events in this story appeared from the perspective of the general public.
 * Like Tegan, Ian and Barbara, and Rose, Dodo returns to London some time after she initially left it. Her surprise at the now-completed Post Office Tower places the events at the end of "Bell of Doom" at least a few months prior to those of The War Machines.
 * It's revealed in NA: Original Sin that Tobias Vaughn had funded Professor Brett's work.
 * The Time Travellers, set before this story (from the Doctor's point of view), reveals that the Doctor's actions in The War Machines altered history. In the original timeline, WOTAN managed to conquer Earth prior to his destruction in 1969.
 * BBC newsreaders Kenneth Kendall plays himself in episode 4, announcing the destruction of the first War Machine.

Timeline

 * This story occurs after ST: There are Fairies at the Bottom of the Garden
 * This story occurs before DW: The Smugglers
 * ST: The Rag and Bone Man's Story takes place during episode 4 of this story.

DVD, Video and Other Releases
VHS release
 * The Doctor Who Restoration Team did very extensive work on this story for the VHS release. In addition to lots of film and video cleanups, and patching censor clips in for many bits missing from the master copy, this included creation of short sections of new footage from stills and off-cuts to cover missing  bits.  Despite this, it still has a small amount of missing material where no video could be found to match the complete off-air audio.  The audio release is complete. (TV broadcasts prior to the video release usually used the unimproved, substantially cut, and very very dirty master.)
