Speaking with Digital Spy, Doctor Who's executive producer/lead writer Stephen Moffat had this to say of Neil Gaiman's much anticipated episode...
"Cybermen (who first featured in the programme in 1966, followed by an appearance in 2011) were always the monsters that scared me the most! Not just because they were an awesome military force, but because sometimes they could be sleek and silver and right behind you without you even knowing... And with one of the all-time classic monsters returning, and a script from one of our finest novelists, it's no surprise we have attracted such stellar names as Tamzin, Jason and Warwick."
Indeed, Tamzin Mel off EastEnders Outhwaite, Warwick Willow/Life's Too Short Davis and Jason Being Human/Psychoville Watkins will star as a "band of misfits" the Doctor will stumble upon while larking about a "mysterious planet."
If you're awaiting the next episode of Doctor Who with baited breath, rejoice, Christmas has come early (doesn't it always) with this here trailer. Really it's just a teaser. OK, really it's just 15 seconds of Oswin/Clara in a fancy hat.
