In the roles they choose, their screen time, and the spaces within which they perform, actresses use light to accomplish their goals. Some would be "Sister Mary Benedict" or "Golda", a passionate saint or a leader of nations, while others, are merely "Ilse" dutifully flying beyond the fog
"... not today or even tomorrow but soon and for the rest of your life..."
only to become "Maria" for whom
"... it was determined, that they should ring first that rose earliest."
yet for herself, Ingrid Bergman chose to live a passionate life because she knew that a passionate light illuminates a life even as it wanes. A dutiful light illuminates the moment of discharging that duty otherwise casting no shadow nor making clear the way for any other act.
Time and space pilfer light. The bitterness of the dutiful choice is to finally understand that all we get is old.
