Doctor Who - The End Of Time Trailer With The Master

We all know the end of David Tennant's run as the Doctor is fast approaching.  Whenever the Doctor is about to regenerate, we always wonder what big catastrophe is going to cause it.  With David Tennant being such a fan favorite, you know the writers have to come up with something big and noble to give this Doctor a proper sendoff.  Looks like we should have an idea now.  Two words... the Master.
 
On December 25th (26th on BBC America), "The End Of Time, Part 1" will air.  Christmas will be canceled and the Master will be up to his usual shenanigans.  Check out this trailer and see if it gives you chills up your spine.
