Proof debuted at the 2005 Toronto International Film Festival and at the time I thought it had the potential to go on to become one of the hot movies for grown-ups to come out of the fest. Instead it was ignored on release, but now people have a chance to revisit the movie on DVD and check out the great performances by Gwyneth Paltrow as the daughter of a brilliant but mentally ill mathematician with Anthony Hopkins the father, Jake Gyllenhaal as the love interest and Hope Davis as her overbearing sister.
Based on the Broadway play, Proof –adapted for the screen by Arthur Miller’s daughter Rebecca—is the story of Catherine, the daughter of a brilliant but mentally ill mathematician who fears she may have inherited her father’s insanity. Complicating Catherine’s life are a domineering sister and a young math student who believes that he has found an important new mathematical proof in her father’s old papers. I think people assumed that this was a movie about mathematics—that it would be dry—but it is not. Proof is an absorbing drama about family, genius and self worth.
