In the tradition of A Beautiful Mind, Proof is a psychological drama about a math genius and the people who worship, care for, and endure him. It's based on the Tony Award-winning play by David Auburn, and for the most part, it works. Catherine (Gwyneth Paltrow) has lost her father Robert (Anthony Hopkins), a math genius whose sanity tanked in his later years. She had put her own life aside to care for him and is now terrified that she suffers from his affliction. Meanwhile, Catherine must contend with Hal (Jake Gyllenhaal), a graduate student intent on mining Robert's notebooks for a proof worthy of publication, and her sister Claire (Hope Davis), a conventional woman who wants to compensate for her absence by controlling everything. Proof is a strong film with intense focus. Its characters are complex and engaging, its central mystery pulls the action forward at a clip, and the performances by Paltrow and Davis are excellent. At the same time, it's a little too slick.
