After setting record-breaking ratings on BBC America, the Doctor Who cast and crew will film a two-part story on American soil for the first time in the show’s history, announced BBC.

Those trying to deduce what the story could be about might start by looking for anything significant that might have happened in a Utah desert during the 1960s. The Doctor, Amy, and Rory start their adventure in Utah and end up in The Oval Office itself, which means one of four different U.S. presidents could make an appearance: Dwight Eisenhower, John Kennedy, Lyndon Johnson, or Richard Nixon.

“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!” said showrunner Steven Moffat, who will write the two-parter.

According to the BBC announcement, production on episodes one and two of the new season starts in Cardiff this month and continues there until March 2011, with Matt Smith, Karen Gillan, and Arthur Darvill will travel to America in mid November to shoot pivotal scenes, and will be joined by Alex Kingston, who reprises her role as River Song.
