Did You Know?


According to the clues given in the movie mainly by Hal (Gyllenhaal) the proof can be the proof of Riemann hypothesis. He says "a very important proof, of a mathematical theorem about prime numbers, which mathematicians are trying to prove, it's historic, you can publish it, give press conferences, all newspapers in the world will talk to the person who have found it". Actually it's one of the Millennium Problems. See more »

X * Y = Z. No Mathematical Proof, but a Proof nonetheless.
13 September 2005 | by (Canada) – See all my reviews

GWYNETH, GWYNETH, GWYNETH! Not having been overly impressed with any of her previous performances, in Proof, Gwyneth Paltrow brings a highly emotional, nuanced, and so finely-tuned performance, I must say this movie this movie a stand-out.

She inhabits her character so fully, I was pulled in and so completely entranced the entire time. In fact, certain words or phrases are reused and have an uncanny allusion to when they were previously said. The effect as that you experience and follow the moments, and the thoughts of the characters, even though they are so deeply imbedded within. I credit Gwyneth and the director with making this work so well. I've never experienced such an organic link between phrases separated in time in a movie before. Wow!

This is a movie about how a daughter, her sister, and a grad student deal with the passing of a great mathematician. While there may be similarities with 'A Beautiful Mind' and even 'Good Will Hunting', knowing there are any such links didn't help me with this movie and I think actually does a dis-service. This movie stands on its own. Ignore any such comparisons.

Acting-wise, there were strong performances all around with Anthony Hopkins giving a top-notch performance. Jake Gyllenhaal's was strong, but perhaps not to the level of his rather awesome performance in Brokeback Mountain.

Good things aside, the one thing that irked me about this film, was that given the strong link to mathematics, how unbelievable some of the dialogue was regarding the 'math. While Gwyneth's and Hopkins' characters pulled off a sense of mathematical intelligence, Jake's character hardly said anything mathematically competent and even came across as flustered in expressing himself mathematically leaving me feeling cheated. In my view, this is chiefly the fault of the screenplay but to a lesser extent in the actor's portrayal. Ignore this rather small point, and this movie passes with flying colours. Q.E.D.
