Didn't see a thread for this fine actress.
Even when I've not been overkeen on her films (Lovely and Amazing) Keener herself is always fantastic value she can play comedy and drama equally well, often within a single part.
Favourite performance? Living in Oblivion, one of the best films about films. Though she's also great in Being John Malkovich.
As talented and as attractive as she is I do wonder why Catherine Keener isn't a star.
