Frank Darabont's description in Shawshank Redemption

“Dark as midnight. Concrete walls rise on both sides. If you imagine them as two huge slices of bread, the meat of this particular sandwich is about three feet of airspace and a dark tangle of pipes between the cellblocks. Rory’s appears, shining his flashlight down the shaft. Somewhere, a rat SQUEAKS.”
