How does Ben Hecht use imagery in The Front Page?

In Shot Four, Hildy's ability to move, her efficacy, again overcomes a visually unnatural image, and her movement becomes firmly established as a metaphor for control. It stands in contrast both with the stark, unmoving angles and lines and the long shadows of the cell room dominated by Earl's cage-like enclosure and with the severely circumscribed, inefficacious "movement" of Earl within the cell, or of the mechanically pacing guard in the background. Hildy moves assuredly where movement otherwise is absent or confined.
