Theory:Doctor Who television discontinuity and plot holes/The Tomb of the Cybermen


 * In episode one, the Doctor and Jamie hold one of the tomb doors closed with their feet.
 * Hardly an error, just a theatrical device; they had to make sure it didn't open, so Toberman could do it. It's actually not that noticeable.--Jesster2 03:44, August 10, 2010 (UTC)


 * The Cybercontroller uses a visible harness to lift Toberman over his head.


 * Toberman returns the favor in episode four by spinning a dummy Cybercontroller.


 * The Cybermen retreat into their tombs backwards, the film having been reversed.
 * Seems like just a practical consideration, and, again, it's not that noticeable.--Jesster2 03:44, August 10, 2010 (UTC)


 * Kaftan and Klieg are locked in the weapon testing room, complete with deadly weapon. (The room features a psychedelic target that can hypnotize humans, with a 'subliminal center you're trained to see', which is not a very Cyberman sort of thing.)
 * There's no explicit reason Cybermen wouldn't make use of a subliminal center. Their brains remain largely human.


 * The Doctor's plan to lock the Controller in the revitalizing cabinet would appear sound were it not for the fact he decides to switch on the apparatus which will return the Controller to strength.
 * The equipment will only lock and restrain the occupant if it is switched on. He knows the Controller will eventually get out. It is simply a delaying tactic.


 * Earlier, when the rocket's fuel pumps were sabotaged, Hopper said that it would take three days to repair them, working non-stop. Then at the end of the story, after far less time than that has passed, he walks in and blithely says, "Well, the fuel system's OK. We can blast off any time"!
 * He may be using a different day time. Also, he may be using the 'Scotty Method' of telling your captain something will take longer than it actually will, so he'll think you're amazing.


 * When the archeological team discovers their rocket has been sabotaged and are distressed at the possibility of spending three days on Telos, no one even considers using the Doctor's ship to escape, or at least to hide in.


 * When Captain Hopper opens the hatch after disarming Kaftan, he pulls an entirely different switch on a different section of the control panel than the one they had identified seconds earlier.
 * Would Victoria really be able to shoot a Cybermat with a handgun with just one shot?
