Such an underrated movie. Colin Farrell, Jon Voight and of course Norton do a great job of not over doing it whilst still being great. Shea Whigham too. It's got this low key, gritty, realistic thing to it which i loved. I think its based on real events from the seven five precinct in New York. This is one of my top 20 movies, I've seen it at least 5 or 6 times. I definitely recommend it
