The pre-publicity for ‘Nightmare in Silver’ indicated that this episode was going to do for the Cybermen what 2005’s ‘Dalek’ had done for their metallic rivals: restore them to scary eminence after a period when they had lost their robo mojo.

We all love a bit of history, especially robot history, right? And there are few bits as fascinating as ‘The Turk’, an 18th century chess playing robot that amazed the folk of the time with its ability to beat a human at the game.

It was one of the first instances of man vs machine, and the concept of The Turk is something that writer Neil Gaiman clearly loves, for it’s embedded deep within ‘Nightmare in Silver’s’ programming.
