While we have seen a lot from Doctor Who‘s wild-west themed upcoming episode this week, not much has been revealed about the following one, The Power Of Three. Most of what we know comes from Steven Moffat‘s introduction to the episode to Radio Times earlier this month.

Check it out below:

“The day the Earth got cubed. The year of the slow invasion. The time the Doctor came to stay.” There have been many ways to invade the Earth, and the Doctor has seen them all. Or so he always thought – and then the human race wakes up one morning and discovers the world has been overrun by… small black cubes. Which then proceed to… do nothing much at all. A plan is afoot, humanity is endangered – but by what and how and, above all, when? For the first time in his world-saving career the Doctor has to call upon the least of his virtues: patience. And the Ponds face something possibly more terrifying than any world-ending apocalypse – the Doctor is moving in! Not just a tale of alien intervention, this is also the story of a nice young couple who happen to have a bow-tied lunatic from space staying in their spare room. It’s halfway between an alien invasion movie and The Man Who Came to Dinner.

We’ve barely seen any footage in the trailers but the BBC has finally decided to release some promotional pictures from the episode. While they don’t show much, it seems like there will be some great character moments between the three main leads with the Doctor moving in.

Early reviews have yet to arrive, but the editor of the Doctor Who Magazine, Tom Spilsbury, has said on Twitter that it was “my favourite episode of Doctor Who in a long, long time. And I love them all! Beautiful, moving, superb.”

The episode will be written by Chris Chibnall (who also wrote the prequel series Pond Life and last week’s Dinosaurs On A Spaceship) and sees the return of Mark Williams as Rory’s dad. Steven Berkoff and Jemma Redgrave also guest star.

The episode will air on September 22, 2012, while a trailer for it will no doubt be shown at the end of this week’s episode, A Town Called Mercy.
