Fan Casting Little Sister in Gore Verbinski's Bioshock

A seven-year-old girl who extracts ADAM from corpses. She is innocent but eerie, skittish but sweet. She draws flowers in chalk, asks Jack to push her on a swing, and calls him her big brother. She is a victim of Tenenbaum's experiments—a child who has never seen a real flower. Her small hand pulling a gun away from Jack's temple saves his life. She is the film's moral center.
