Gwyneth Paltrow, Jake Gyllenhall and Anthony Hopkins star in “Proof” the movie based on the play. Whenever a movie is based on a play you can bet that it will be dialogue driven, and this film certainly is. The lines are well written, and sharp, but somehow not translated well to the big screen. They are the kind of lines that make you aware of the writing. Gwyneth Paltrow gives an outstanding performance as the stressed and worn out daughter of a genius mathematician. As his caretaker, she loses herself, only to be left with bitterness and confusion when her job is done. She plays it on the edge as she struggles to regain her identity, and we watch her teeter precariously. Anthony Hopkins is his usual brilliant self. And Jake Gyllenhall is so natural and comfortable in his skin, he’s a joy to watch.
