BBC America has debuted its own trailer for the sixth season of Doctor Who that's not nearly as creepy, nor quite as epic, as the BBC version. However, it features a lot of new footage, including several glimpses of season-premiere guest star Mark Sheppard (Supernatural, Battlestar Galactica).
Doctor Who returns at 9 p.m. ET/PT April 23 with "The Impossible Astronaut," in which the Doctor (Matt Smith) and his companions Amy (Karen Gillan) and Rory (Arthur Darvill) receive a secret summons that takes them from the Utah desert to the Oval Office in 1969. The two-part season premiere, which continues the following week in "Day of the Moon," marks the first time the sci-fi series has filmed on location in the United States. Alex Kingston also reprises her role as the enigmatic River Song.
