Chinatown, Rosemary's Baby, The Pianist.  When people discuss Roman Polanski’s work it’s usually those films that come to mind.  However, when I think Polanski, Death And The Maiden is often first and foremost in my head.  The three aforementioned films are great - but for me, Death And The Maiden, is maybe my favorite of them all (which is saying a lot given how good Chinatown and Rosemary's Baby are).
