Finally watched the film "Proof" while I was half asleep. There was absolutely no chemistry between Gwyneth and Jake. Expected more but quite liked the twist of the film. Mrs. Paltrow (Martin!) is indeed an expert in playing depressed and miserable roles. Her role in Proof reminded me of the one she played in Moonlight and Valentino. She is a great talent though; there is no doubt about that.
Recommended on DVD!
