The Cyberman were originally created to fill the void left by the Daleks when Terry Nation, creator of the deadly pepperpots, went off to make films with them and tried to set them up with their own series in America.

Cybermen helmets are notoriously claustrophobic - the poor actors had to be literally screwed into them. During their first adventure, The Tenth Planet, some of the Cyberman actors passed out under the hot studio lights.

The term ‘cybernetics’ was first coined by mathematician Norbert Wiener in 1948. It derives from the Greek word for 'helmsman' and was used to describe the study of feedback systems.

Great Cybermen plans include diverting Halley’s Comet towards Earth and taking over a base on the Moon by poisoning the crew’s sugar. Sweet.

Professor Kevin Warwick of Reading University is the world's first real Cyberman. A leading expert in Cybernetics, Warwick has microchips embedded into his arm which allow his nervous system to communicate with computers.
