When Doctor Who returns in less than two months there won't just be a new Doctor regeneration (brought to life by Peter Capaldi of The Thick of It and In the Loop fame), but also new supporting characters and/or other-worldly enemies to boot - along with some familiar faces, both friendly and... well, not so friendly to The Doctor's cause. In the former category, we have Clara (Jenna Coleman) and Danny - one of Clara's fellow teachers, played by Samuel Anderson (Emmerdale).
The list of people set to make guest star appearance on the resurrected Doctor Who's eight series includes Keeley Hawes (Line of Duty), Ben Miller (Death in Paradise), Hermione Norris (MI-5), Tom Riley (Da Vinci's Demons), Frank Skinner (Room 101) - and Michelle Gomez, as revealed in a fresh announcement from the BBC.
A veteran of the stage and small screen alike (see: the TV series Carrie & Barry, Green Wing and Bad Education), Gomez is described as a longtime acquaintance by current Doctor Who show runner and lead writer Steven Moffat - who also claims that "she's everything we need - brilliant, Scottish, and a tiny bit satanic."
You can see Gomez in costume below, as the prim and properly-dressed Gatekeeper of the Nethersphere; below that, however, is an official behind the scenes image from Doctor Who season 8, showing Capaldi's Doctor and Gomez' Gatekeeper together - alongside some other villain types that will properly ring a bell for longtime Whovians.
Exactly what sort of trouble the Cybermen will be getting up to in Doctor Who season 8 and their connection to Gomez' Gatekeeper, remains to be seen. Moffat has teased in the past that he's striving to mix things up more in Doctor Who S8 compared to his work on the past three seasons. That probably doesn't mean the Cybermen will be abandoning their quest to "upgrade" all varieties of lifeforms - as surprising as that would be, anyway.
Beyond that, both Moffat and marketing for season 8 have teased that Capaldi's Doctor will perhaps be a bit overall darker in his outlook than, say, Matt Smith's Doctor before him. Given his preferred attire, though, it seems safe to assume that the new Doctor won't be altogether that serious, though. At least, not as much as he'd like to believe himself to be.
Doctor Who Season 8 premieres on August 23rd, 2014.
