The Day of the Doctor - 50th Anniversay Special is set to celebrate Doctor Who's official birthday on Saturday, November 23. Former Doctors Matt Smith and David Tennant team up with Jenna-Louise Coleman, Billie Piper and John Hurt for this once in a lifetime event. Check out the trailer.

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. All of reality is at stake as the Doctor's own dangerous past comes back to haunt him.
