Theory:Doctor Who television discontinuity and plot holes/The Green Death


 * In episode one, when Dai Evans is on the telephone in the mine, an arm appears to the bottom right, giving him his cue to speak.


 * In episode five, the Doctor escapes from Global during the day. When Yates is caught it's dark, but the next scene, on the slag heap, is in daylight again.


 * The dodgy CSO in episode three results in the cart bottom vanishing.


 * Why is the mine still being checked if it's been closed down as an uneconomic pit (cf. the sealing of mines in 1992)?
 * Ecological reasons.


 * Why is there a camera in a pipeline?
 * To check for an obstructions.


 * The function (and lines) of Elgin are taken up by James half way through the story.


 * When Jo is helping Bert around a corner, she knocks a support strut out of position.


 * When Jo sits up in the cable car, her helmet doesn't have a lamp. Switch to the medium shot and it suddenly does.


 * When the Doctor picks up the green egg, it squeaks, revealing it to be a painted balloon.


 * When Jones is looking through his microscope, the objective is rotated so that none of the lenses actually point at the slide.


 * When Yates breaks James' conditioning, the latter falls against the wall, which shakes.


 * When Benton rescues Cliff and Jo, the ground shakes and flexes.


 * The Doctor resists BOSS's programming by calculating Pi. He recites the first five numbers and continues silently. But he gets it wrong, giving the first five digits as 3.1416. This is only correct if Pi is rounded off after five digits. The correct sequence would be 3.14159265…
 * The rounded number is good enough for his equation, then he silently continues calculating the equation, not reciting Pi.


 * In the climax, not one but two heavy consoles move as Stevens frantically operates the controls.


 * A shot of the brown fungus rolling between two maggots is repeated.
