  • Trivia

    • In the original script, the Doctor looked around the room to find the secret switch that is always hidden in such rooms to open the door. But Script Editor Eric Saward thought that wasn't clever enough and introduced the idea of the musical lock, with the key to the puzzle contained in a painting in the room. Such devices are a favourite of Borusa's: saying "There's nothing more useless than a lock with a voice print" twice opens a voice-activated lock in The Invasion of Time.
