Chicago? C'mon, really?
Granted, this movie was made in 93 so the city was different back then, so I won't nitpick on city choice. But where would they have been going to see a major boxing match that they wouldn't have been able to hop back on a major road or something? Allstate arena? That's up in Rosemont. Definitely not the United center. They make it seem like this is near the south side, but but there's no where they'd be headed that they would end up in that situation.
I happen to love this movie, I saw it once in the theaters and it's on again now. Back then I didn't realize it was supposed to be in "Chicago".
