Incarnations

Games

 * The game of chess was invented by the Time Lords.

Cultural references from the real world

 * Porridge is inside an undefeated "automated" chess player. This is very similar to real-world, who was too exhibited as an undefeatable chess-playing machine, but was actually controlled by a man inside.

Story notes

 * The episode's title, Nightmare in Silver, is reminiscent of Silver Nemesis, in that, in both cases, the "Silver" is referring to Cybermen.
 * A working title for the episode was The Last Cyberman.
 * The Cyber-Doctor answers to Clara's question of "More Cybermen?" with "They're waking from their tomb right now." which is a possible reference to the television story TV: Tomb of the Cybermen.
 * When the Doctor lets the Cyber-Doctor access his memories on regeneration, his previous ten incarnations are seen. Each image of an incarnation is taken from photograph stills used as promotional material during the respective actors' tenures.
