MTV Interviewed Steven Moffat and he talked a little about the first episode of the new season:
MTV NEWS: Right off the bat, let's talk about the season premiere, since most "Doctor Who" fans will find a way to see it this weekend no matter where they live. Where does the episode (titled "The Eleventh Hour") find The Doctor and his new body?
STEVEN MOFFAT: Assuming you've seen "The End Of Time," it starts a heartbeat later. We don't miss anything. It's what happened after [Smith] shouted, "Geronimo!" so we're straight into the TARDIS crashing. And unlike just about all the previous regeneration stories, The Doctor gets absolutely no time to rest up. We see almost in real-time the first hour of his new life.
He finds himself pitched straight into an appalling crisis that just gets worse and worse and worse. And he's not done yet — he's not quite ready. He's not even sure who he is yet, but immediately he's put into a terribly dangerous situation that escalates and escalates to the point in which he has 20 minutes to save the planet and no equipment to do it.
