Bluebeard (1901, dir. Georges Méliès)
"King Bluebeard turned all the keys of the castle over to his wife, saying, ‘You may go anywhere in the castle, unlock everything, and look at anything you want to, except for one door, to which this little golden key belongs. If you value your life, you are not allowed to open it!’
'Oh no!' she said, adding that she surely would not open that door.  But after the king had been away for a while, she could find no rest for constantly thinking about what there might be in the forbidden chamber. On the morning of the fourth day, she could no longer resist the temptation, and taking the key she secretly crept to the  room, stuck the key into the lock, and opened the door.”
-Charles Perrault’s Bluebeard
