Aristotle said time is a measure of change, and this movie is about changing in time, through time, while remaining the same person. That's a philosophical paradox and a moral dilemma. But 'Casablanca' says it's possible. You can have both. That's what it means. And that's my wish for you: that you would have both.
Robert McKeeA culture cannot evolve without honest, powerful storytelling. When a society repeatedly experiences glossy, hollowed-out, pseudo-stories, it degenerates. We need true satires and tragedies, dramas and comedies that shine a clean light into the dingy corners of the human psyche and society.
