An interesting essay over at Fandor.com comparing two stage adaptations being released this year, Carnage and A Dangerous Method (The Ides of March and War Horse are two other prominent stage productions to be brought to film this year). I agree with the writer who says that the trick in making Carnage is successful is choosing the right actors. Polanski, I think, did a marvelous job as director hemming in the story. At any rate, the subject of Keira Knightley in A Dangerous Method is brought up:
Knightley has taken a lot of undeserved flack for the extremity of her performance in the early scenes of A Dangerous Method, when her character is manically all-over-the-place. Her sexually unhinged Sabina often falls into a jutting mannerism with her chin when she’s really unsettled, a bold choice on Knightley’s part; it looks like she’s chosen an animal of some kind as a pattern for Sabina’s physical behavior, and she goes all-out with this choice. As someone with more than a passing acquaintance with the mentally disturbed, all I can say is that Knightley’s chin mannerism here is exactly the kind of protective physical thing that people who are clinically ill often cling to, and it is also exactly the kind of thing that actors shy away from when they are playing mentally disturbed characters because it is wildly unflattering.
