Xmas Filming to Begin After World Tour

Steven Moffat has confirmed that filming on this year's Christmas special will begin after the Doctor Who World Tour concludes. The tour is set to make its way through several continents before ending in time for the new series. Speaking to Radio Wales, the showrunner said

Peter and Jenna only wrapped on the show yesterday. We’re not letting them off the hook because they’re going to be doing the two premieres today, then they’re going off on the World Tour, then they’re coming back to shoot Christmas.
