The Lady, or the Tiger? (1969)

"The Lady or the Tiger?", is a short film that ends ambiguously in a cliffhanger. A barbaric king in times past would adjudicate/punish crimes in his kingdom with the following choices: the accused criminal could choose door #1 or door #2. Behind each separate door was either a man-eating tiger, or a maiden for him to immediately marry. So, the fellow would either immediately be eaten by the tiger or be immediately married, the choice was funeral or wedding. The king had a daughter who was just as cruel as he was. She was having a romance with a fellow the king did not approve of, so the man was sentenced to choose between door 1 or 2. The Princess knew what was behind each door and could subtly signal to her lover which door he should choose. However, the king placed his daughter's rival for her lover's affections in the place of the maiden. So, will the Princess send a signal to her paramour that will send him to his death, or into the arms of her hated rival?
