The BBC has released three new Doctor Who promo pics for next week's episode, "The Power Of Three," bringing the total up to six. We have them for you guys at the bottom of the post!

In an interview with Radio Times earlier this month, Steven Moffat had the following to say:

"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.

"The Power of Three" airs on September 22 on BBC America!
