This is the new trailer for the Doctor Who special Waters of Mars that will play in the UK in the Fall. The official release date is still unknown. I have to say that it looks to be a scary one.
You can go here for the official BBC synopsis.
After this, there will only be two more specials playing over the Christmas Holiday, plus a Sarah Jane 2-parter episode and then David Tennant's Tenth Doctor will make way for Matt Smith's Eleventh. I'm already crying.
