The principle of Creative Limitations calls for freedom within a circle of obstacles and restricted boundaries. Talent is like a muscle: without something to push against, it atrophies. So we deliberately put obstacles in our path - barriers that will inspire us. We disciple ourselves as to what to do, while we're boundless as to how to do it.
Robert McKeeAristotle 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 McKeeWhereas life separates meaning from emotion, art unites them. Story is an instrument by which you create such epiphanies at will, the phenomenon known as aesthetic emotion...Life on its own, without art to shape it, leaves you in confusion and chaos, but aesthetic emotion harmonizes what you know with what you feel to give you a heightened awareness and a sureness of your place in reality.
