For those who haven't read Proof, try reading it. The play won a Pulitzer, and it's wonderful. Once you have, go rent the movie. It's got Gwyneth Paltrow, Anthony Hopkins, and Jake Gyllenhaal. GP is absolutely amazing as Kate. STUNNING. As an actor, I think there are a alot of things that an actor sees in his/her head when reading a script. Paltrow so MUCH with the dialogue that she's given that it's phenomenal. An entire character is fleshed out through ticks,jerks, glances, and breaths.

Wonderful movie.
