The BBC is breaking the bounds of time and space to celebrate 50 years of its cult sci-fi series Doctor Who. On November 23rd, the network will broadcast its anniversary special, "Day of the Doctor," in 75 countries simultaneously (including the U.S., on BBC America). The special will also air in select movie theaters in 3D, and will replay again in theaters on November 25th.
A trailer released on Friday night by the BBC shows current (and outgoing) Doctor Matt Smith teaming up for the first time with the 10th Doctor, David Tennant, along with companions Clara Oswald (Jenna Coleman) and Rose Tyler (Billie Piper). John Hurt will also appear as a "forgotten" past incarnation of the Doctor, and Joanne Page plays Queen Elizabeth I. "In 2013, something terrible is awakening in London’s National Gallery; in 1562, a murderous plot is afoot in Elizabethan England; and somewhere in space an ancient battle reaches its devastating conclusion," BBC America teases. "All of reality is at stake as the Doctor’s own dangerous past comes back to haunt him."
Doctor Who began its broadcast on November 23rd, 1963 and grew to become the longest-running sci-fi series in television history. Celebrations of the anniversary will begin on BBC America a week before "Day of the Doctor," with special programming including marathons, behind-the-scenes specials and a look at the physics that allow the Time Lord to travel through space and time.
