Chicago = Gotham already?

According to this website, location scouts have already begun checking the city for locations for the next film. And then there's this bit saying that they may begin filming later this year. Hooray!

I don't know what it is that makes me so gleeful to see Chicago dressed up as Gotham City. But it really does make me happy. I just wish I still worked downtown, so that I could see awesome stuff like this now and then. This reminds me that I really need to re-watch The Dark Knight, seeing as how I've only seen it once. It was just so heavy that I haven't psyched myself up to watching it again. I should, though, especially considering I've forgotten most of the film...
