Doctor Who episodes (2005–present)

The episode is set in London in a parallel universe. In the episode, the businessman John Lumic (Roger Lloyd-Pack) has overthrown Great Britain's government and taken over London. A human resistance movement seeks to stop Lumic's plan to convert humanity into Cybermen by destroying Lumic's transmitter controlling London's population.

The episode was relatively popular[according to whom?] as it was the climax to the first story to feature the Cybermen since the show's revival. It has an Audience Appreciation rating of 86.



The episode opens immediately after the events of "Rise of the Cybermen". The Cybermen have the Tenth Doctor, Rose, Mickey, and the Preachers surrounded. The Tenth Doctor uses the recharging power cell from the TARDIS to overload the Cybermen, disintegrating them. The group escapes with Pete Tyler, but Jackie is trapped inside and presumed dead. As they flee, Pete explains to the Preachers that he is "Gemini", the Preachers' secret source of information on Lumic. Pete had thought he was communicating with law enforcement but accidentally involved the Preachers instead. From his hovering zeppelin, John Lumic orders the Cybermen to activate the EarPod devices and use them to control the people of London and bring them in for conversion.

When they reach London, the group discovers Lumic's zeppelin moored near the power station and head towards it. Ricky is killed by the Cybermen while trying to scale a fence to meet Mickey. After inspecting the power station, the Doctor determines that they must destroy the EarPod transmitter located on the zeppelin. Mickey and Jake decide to board the zeppelin, Pete and Rose pose as humans being controlled by EarPods, and the Doctor and Mrs. Moore try to find their way to Lumic. Pete and Rose are captured by the Cybermen when a now-converted Jackie catches sight of them. Mrs. Moore is killed by a Cyberman, but the Doctor discovers that each unit contains an emotion inhibitor to prevent their human side from taking over. He deduces that if he disables the signal from the inhibitors, the realisation of what they have become will kill the converted Cybermen. The Doctor is captured by a Cyberman and taken to see Lumic.

In Lumic's office, the Doctor discovers the Cybermen have captured Pete and Rose and have forcibly converted Lumic into the Cyber Controller. Mickey and Jake successfully disable the transmitter from the zeppelin by taunting a Cyberman into destroying the transmitter's power source. On the factory floor, the humans yet to be converted are snapped out of their trance. Initially confused, after seeing the cyber-conversion machines above them they quickly put two and two together and flee the factory in terror. The Doctor attempts to reason with Lumic to stop the conversions, but Lumic states that the Cybermen will simply take humanity by force. The Doctor, via the surveillance camera in Lumic's office, subtly communicates with Mickey on the zeppelin to find the inhibitor code. Mickey locates the code in the computer and sends it to Rose's phone. The Doctor plugs the phone into the computer systems, causing the inhibitor signal to drop and sending the army of Cybermen into despair. The conversion facility begins to go up in flames, and the group escapes to the zeppelin leaving Lumic to die. At the zeppelin they realise that Lumic is following behind them and Pete uses the Doctor's sonic screwdriver to sever the ladder, causing Lumic to plunge to his death in the exploding factory.

The Doctor, Rose, and Mickey return with Jake and Pete to the dead TARDIS. The Doctor plugs in the recharged power cell and revives the TARDIS. Rose reveals to Pete that she is his daughter from the parallel universe. Overwhelmed, Pete refuses Rose's offer to board the TARDIS and walks away, causing her to cry. Mickey, feeling that Rose no longer needs him, decides to stay in the parallel universe to help care for Ricky's elderly grandmother and to help the Preachers stop the remaining Cybermen, with Mickey ending his relationship with Rose. After the TARDIS dematerialises, Mickey and Jake plan to destroy a Cybus Industries factory in Paris.


According to an interview with Andrew Hayden-Smith, and comments given by Russell T Davies in a press conference, Ricky and Jake were initially intended to be gay and lovers.[1][2] A deleted scene included in the Complete Series Two DVD box set confirms this.

This episode, along with "Rise of the Cybermen" was produced in the same production block as the series finale story, "Army of Ghosts"/"Doomsday". Location shooting took place at the Coal Exchange and Mount Stuart Square, Cardiff Bay.[3] Footage from "Rose" — specifically, the destruction of the Nestene Consciousness — was reused as part of the destruction of the Battersea Cyber-conversion facility.

Outside referencesEdit

Pete derisively calls the Preachers "Scooby-Doo and his gang" and compares their van to the Mystery Machine. The marching of thousands of mind-controlled Londoners to Battersea (referred to by the Doctor as "sheep") echoes the Pink Floyd song "Sheep" from their album Animals, where the sheep are led into the "valley of steel" to be slaughtered. The album also features a shot of Battersea Power Station on its cover, with a pig floating above it just like Lumic's own airship. Pink Floyd is known for incorporating the Doctor Who theme music into live performances of the song "One of These Days".

As noted by Noel Clarke on the commentary, Mickey phones Rose and says "I'm coming to get you!", which echoes the Ninth Doctor's words to her at the climax of "Bad Wolf". The words also constitute a catchphrase used by Davina McCall on the UK television programme Big Brother, the latest series of which started two days prior to the episode's broadcast and which also featured in "Bad Wolf". The climax of the episode echoes that of Casablanca, with Mickey in the role of Rick Blaine and Rose as Ilsa Lund. Indeed, Mickey adopts the name "Ricky" and talks about freeing Paris.

Broadcast and receptionEdit

The average overnight viewing figure for this episode was 6.85 million (a 36% share), peaking at 7.7 million. The final figure rose to 7.63 million.[4] It received an Appreciation Index of 86.[4]

This episode was released together with "Rise of the Cybermen" and "The Idiot's Lantern" as a basic DVD with no special features. It was also released in the complete series 2 box set and the Doctor Who Cybermen collection.

IGN's Ahsan Haque gave "The Age of Steel" a rating of 7.9 out of 10, praising the way Mickey became independent. However, he noted that it worked as a "popcorn episode", with the Cybermen story being a "letdown" and "by-the-book", with the conversation between the Doctor and Lumic about emotions something that was commonly covered in science fiction.[5] Nick Setchfield of SFX gave the two-parter a positive review, highlighting Harper's direction which he felt added imagination and menace to the Cybermen and the parallel universe. However, he felt that Lloyd-Pack's performance was too over-the-top for the current "subtler" incarnation of Doctor Who, which made him come across as "jarringly two-dimensional".[6]
