Yeah... could make a good list of those films... The Paper Boy from a few years back, Bad Lieutenant (the re-make), parts of Angel Heart etc Maybe Midnight in the Garden of Good and Evil.
AC - we actually got it mainly for winter, the houses here are built to be cool and there is no heating, at night in Nov to Jan it can get down to near zero at night and it's unbelievably cold in the flat. Though if it gets above mid-thirties then we use it for cool too I guess. We certainly will if it gets to 44 again (that's 111 F) cos it's unbearable, like this heavy hot hand just holding you down. The cats aren't built for it either, think they could die, last time we had to put Leo in the fridge but I was really worried about shutting the door and him asphyxiating.
