I don't think Sorkin would be allowed to make a film about MLK or Malcolm X. I hope not, anyway.

If you've never seen the sequel to Blues Brothers, it is very bad. Although it managed to show even more Chicago cops crash their cars than the original.

I mostly can't think of another Chicago-based moment in labor history. It looks like there are plenty, though.
