At the end of Part 1, the Cybermen have landed on Antarctica in the not-too-distant future year of 1986, right on top of the underground UN research and space-control base, and killed the handful of luckless soldiers who happened to be up on the snowy and windswept surface at the time.
Down inside the base, General Cutler is scoffing at the Doctor’s statement that there will be visitors from that other planet that’s approaching Earth and looks just like it, except upside-down to our traditional north/south perspective. Both the Doctor and General are unaware that the visitors have already arrived.
Up on surface, the Cybermen throw the winter cloaks they’ve taken from the dead men over their shoulders and distinctive headgear as a sort of makeshift disguise, and head down through the hatch into the base. It’s not a very good disguise, but it does the trick; no one notices them coming down the stairs into the control room until they throw off the coverings. Polly screams.
I’ve never cared much for the Cybermen later on, either in the Doctor Whos I watched growing up, or in the New Whos. They seemed like clunkier Borg without the Cenobite S&M panache.
But I like these very first Cybermen as they introduce themselves after zapping another soldier or two. They are believably what they say they are–people who were once very like the Earth’s humans, but they’ve had to modify themselves and replace some body parts to survive as the environment on their own world, Mondas, grew more hostile to life. Their hands are bare and still obviously human. The extra features on the DVD tell me this was a mistake and the costume department forgot to order silver gloves, but I think it’s a very good touch, intentional or not.
The voices of the Cybermen are done by other actors offscreen, which creates another nice touch: the Cyberman “speaking” only drops his stocking-covered mouth open and doesn’t move or close his jaw until his speech is completed. What we hear is a creepy, high-pitched, sing-song voice that sounds electronically modulated, emphasizing syllables at random and breaking words or sentences up in weird places. It’s my favorite thing about these first Cybermen, and I think it’s a pity that this style of speech was dropped when they returned in later episodes. It’s as distinctive in its way as the hysterical Dalek shrieks.
