Based on the Broadway play of the same name, Gwenyth Paltrow portrays the daughter of a brilliant but mentally challenged mathematician (Anthony Hopkins) recently deceased. Enter her sister (Hope Davis) orchestrating the funeral, only to find that the depressed Paltrow, has inherited more than she bargained for with her father’s brains and his illness. Jake Gyllenhaal portrays a gifted student who recognizes her brilliance, caught in a romantic struggle between the proof in notebooks (also called Mathematical proofs) and his affair with Paltrow. Filmed ironically when Paltrow’s real life dad died, she gives her usual Oscar worthy performance, as in her recent movies “Emma” and “Sylvia” with an unintentional pedigree and class. But if her last movie was the story of the depressed/suicidal Sylvia Plath’s life, “Proof” is “Sylvia” but this time with a touch of in-control chutzpah. Two crowns.
