During writing Davies had trouble coming up with how Mickey was supposed to be captured by the Nestene Consciousness while waiting for Rose in the car, and finally realised he could be lured by a plastic wheelie bin. He commented that such instances of the ordinary being made scary made "Doctor Who" unique. Davies had to take out "oblique" references to the Autons being like terrorists, as the Eye was once a target of a terrorist attack. The entrance of the Doctor was something much debated; Tranter and other members of the production team wanted it to be more dramatic, but the scene was never reshot. Davies remarked that it reflects Rose's point of view, whereas a more dramatic entrance would reflect the audience's excitement at the Doctor coming back. The scene in which the Auton arm attacks in the Tylers' flat was originally much longer, but was revised. The episode originally underran by several minutes, and a scene with the Doctor and Rose walking was added a month or so later.
