Superb acting, Wonderful photography takes one into the 1930s era of the Chicago Gangsters. I thought I knew the story, but most was new to me. The only thing that bothered me was trying to keep track of who was a "good guy" and who a "bad guy." With the dress of the day, long coats and fedora hats, it was hard to keep the gangsters apart from the FBI agents. Along the same lines, I had trouble identifying who got blasted away in the intense gun fights. Was Baby Face Nelson killed? Oppps, guess not, as he shows up in the next scene alive. (I think). All in all, a great thriller that might gather some awards, but not the top ones, imho.
