Hedgewick’s World of Wonders was once the greatest theme park in the galaxy, but it’s now the dilapidated home to a shabby showman, a chess-playing dwarf and a dysfunctional army platoon.

When the Doctor, Clara, Artie and Angie arrive, the last thing they expect is the re-emergence of one of the Doctor’s oldest foes. The Cybermen are back!

‘Nightmare in Silver’ airs at 7pm on Saturday 11 May on BBC One. To whet your appetite, here are ten hints for the episode…

» The Cybermen are doing all sorts of  new things and are damn clever.

» The Doctor evokes a Batman villain.

» We find out something new about a Time Lord invention.

» Definite vibe of ‘The Doctor’s Daughter’ going on here.

» Matt does mean impersonations of a certain two actors.

» A Torchwood alien makes an appearance.

» Definite vibe of ‘Kinda’ going on here.

» An alien from The Sarah Jane Adventures also pops up.

» In general, keep your eyes peeled for other returning monsters and aliens. And Doctors.

» Clara is most definitely the boss.
