Trivia / Doctor Who 2010 CS "A Christmas Carol"

  • Acting for Two:
    • Old Kazran and Kazran's dad are both played by Michael Gambon. Leads to a heartbreaking moment when young Kazran calls his old self "dad?"
    • Likewise, Young Benjamin, and the unnamed younger Pettigrew in the present are both played by Bailey Pepper.
  • The Cast Showoff: Katherine Jenkins, better known for being a Glamorous Wartime Singer, plays Abigail. Of course she ends up singing.
  • Development Gag: Eleven produces a picture of himself with Einstein towards the beginning of the special. Matt Smith wrote fanfiction about the Doctor meeting Einstein after being cast to prepare himself for the role.
  • Genius Bonus: It's recently been discovered that great white sharks really can live at least 70 years, to judge by growth-ring patterns in a large male salvaged after its death.
  • You Look Familiar: The starship captain is played by Pooky Quesnel, who would later go on to play Dorothea Ames in the spinoff Class.
