Trivia / The Sarah Jane Adventures, S5 E1&E2: "Sky"

• What Could Have Been:
  • Matt Smith was to have appeared as the Doctor, but due to his commitment to Doctor Who, he was unavailable, so the Shopkeeper replaced him.
  • Sky chose to stay with Sarah Jane at the end of the episode, but with the sad passing of Elisabeth Sladen, and only four more episodes filmed, we will not see her character develop that much.
