Advent Calendar Day Ten: Doctor Who Teasers

So, Doctor Who: A Christmas Carol is on its way this festive season. Here are my 10 teasers for what's been called the most Christmassy special yet:
1. Amy and Rory are honeymooning on a space liner that you may (or may not, might be a different one) recognise the name of...
2. Kazran Sardick is the head of Sardicktown, and the Scrooge character of the tale.
3. The Doctor has to convince Sardick to change his ways- but why?
4. "I'm a ghost of Christmas Past"
5. A love story spanning over a decade is going to form a crucial part of the special.
6. We'll see a young Sardick, but will Kazran see his future as Scrooge did?
7. "Time can be rewritten." "People can't"...can they?
8. Katherine Jenkins sings. Yes, really!
9. The mystery of the flying shark unfolds...
10. Expect another hint about the Silence and/or River Song hopefully in the episode but definitely in the Series 6 'Coming Soon' trailer!
