What's your favorite Chicago movie?

There are certain movies that just make you proud to be a Chicagoan, some that are just great movies and some that just suck. I'm partial to the classics such as The Blues Brothers, Ferris Beuller's Day Off and The Untouchables. But I also liked Backdraft, Eight Men Out, The Fugitive, The Negotiator and High Fidelity just to name a few. But I'm curious to see what other movies out there strike a Chicago chord.>
