The Moonbase (TV story)

"There are some corners of the Universe which have bred the most terrible things. Things which act against everything we believe in. They must be fought."

- The Doctor

The Moonbase was the sixth story of Season 4 of Doctor Who. The return appearance of the Cybermen solidified their place as one of the series' key villains. This story was the first in Doctor Who history with sequences taking place on Earth's Moon.

Synopsis
The TARDIS arrives in 2070 AD on the Moon, where a weather control station under the command of a man named Hobson is in the grip of a plague epidemic - in reality the result of an alien poison planted by the Cybermen.

Polly realises that as the Cybermen's chest units are made of plastic they must be vulnerable to attack by solvents. She and her friends manage to destroy all the Cybermen on the base with a 'cocktail' of such chemicals shot at them through fire extinguishers.

A second wave of Cybermen advances across the lunar surface but, prompted by the Doctor, Hobson uses the base's gravity-generating weather control device, the Gravitron, to send them flying off into space.

 * This is the first story in which John Levene (who later played Sergeant Benton) appears.
 * In an early edit of the script the Cybermen had names.
 * Talkback from the headphones of the crew on the studio floor is clearly audible at times during episode four (the same problem as had earlier caused the opening episode of the first Dalek story to have to be remounted) - for example, a voice can be clearly heard saying 'cue' at the start of the scene where the controlled scientists are first activated by the Cybermen.

Discontinuity, Plot Holes, Errors
