I've seen this movie soooo many times.

A few things I've noticed:

1. the Warden is constantly talking about righteousness and piety, while being a vulgar and cruel man. A friend of mine didn't like the "fart in the wind" line, but I explained it shows how he's a crude and vulgar man, not the pious and pristine man he present shimself as.

2. Andy was baptized in shitwater. I just think this is beautiful and hilarious, from an atheist pov. That to clean himself of the stink of the corruption of Shawshank, he had to literally crawl through five-hundred yards of shit-smelling foulness.

3. "Geology is the study of pressure and time". Underrated line. While pressure may not have been overwhelming, the function of time and pressure gave Andy the means of escape. His pressure was such that he found himself useful to the protectionary staff and off-limits to harmful actors, but he was also an innocent man and deserved freedom. And in time he weathered a wall into a hole, busted through a chemically corroded pipe, and wriggled his way through five-hundred yards of shit-smelling foulness I can't even imagine (oh, and financially set himself up). Or maybe I don't want to.
