"The Doctor has visited every weird and wonderful planet you can imagine, so he was bound get round to America eventually! And of course every Doctor Who fan will be jumping up and down and saying he’s been in America before. But not for real, not on location - and not with a story like this one! Oh, you wait!"–
Steven Moffat, commenting on a special two-parter filmed in America for Season 6 of Doctor Who.
Key scenes will be filmed in Utah for a story set in the late ’60s in which the Doctor, Amy and Rory find themselves on a secret summons that takes them on an adventure from the desert in Utah - right to the Oval Office itself.
