Question: When Andy tells the warden how Tommy knows who really murdered his wife, the warden sympathetically says that Tommy made up the story to impress Andy, and he's surprised that Andy believed it. He also says they'd never be able to find that Elmo guy, and even if they did, he'd never confess. Isn't the warden essentially admitting he thinks that Andy is not guilty? Otherwise he'd just say 'I don't believe you, I know you were the one who killed your wife.'.
Question: I'm not sure if this is an actual mistake or a question: when Andy is escaping, we see him climb down something before he leaves the prison, (scaffolding, I think) and he is wearing boots or shoes of some kind. How could he do that since he left his shoes in the shoebox for the warden to find? The warden's shoes were safely tucked away in the plastic bag Andy had attached to his foot by the rope. It wasn't like he could carry a spare pair when he went to the warden's office to close up for the night.
Question: Why would Heywood start chanting "fresh fish"? Betting on who will break down is pretty bad, but I understand they probably have nothing better to do. But what was the point of starting the chant? He seems to feel bad when Fatass is beaten to death, but what was he expecting to happen?
Question: How did the inmates on rooftops manage to get their hands on beer?
