20. The Mysticism Of An Undiscovered Egypt
Magic and Ancient Egypt often go hand-in-hand, since the mystery of the ancient pharaohs helps to highlight the glamorous nature of the act.
If audiences watch closely during the magic act of illusionist, Virgil (J. Paul Moore) at which Alfred Borden (Christian Bale) meets Sarah (Rebecca Hall) for the first time, they will see two guardians of Tutankhamun's tomb standing at either end of the magician's stage.
Since The Prestige takes place during the 1890s and King Tut's tomb was not discovered until 1922, the presence of the guardians of that tomb on any sort of stage would be a physical impossibility.
