Can't believe not one mention of HEAT. or Ronin. I'm not even a particular DeNiro superfan or anything. I absolutely love movies and it's a revolving list of flicks that I'd mention as my favorite depending on the time of day. But Heat and Ronin (and Rocketeer) are always on it for me. I can watch any of them nonstop back-to-back. If I were to truly put down my favorite, I probably couldn't whittle it down to a top 20.
