We enjoyed the movie and felt the actors played their roles well. No one is likely to get any big awards but if you have a couple of hours to spend give this movie a try.

Proof was a play assigned for a theater class I took in college. I remember the students reading lines and acting it out. I was intrigued by a brilliant mind gone mad drawing similarities to A Beautiful Mind. I think the film holds up to the play, or students in my review.

I did not get past the first 40 minutes of this movie. I found it riddled with clichés and very boring. It is also an example of my latest visual pet peeve, the permanent quarter inch stubble on the lead actor's face. This guy didn't even shave for his mentor's funeral! But you know he must shave sometimes, otherwise he would have a beard.... It's Hollywood shorthand for "I am a quirky free spirited man" and it annoys the heck out of me!

very good! Both Paltrow and Hopkins were outstanding in their roles :)

I don't think Gwyneth Paltrow is directed to act or recites such script as she is worthy of. This is the primary reason I have rated it thusly. Other than Paltrows lines and directing I would've given this film at least a 4.5 The mathematical concept really grabs me.

Great acting, the realization of just how insane her father was truly heartbreaking.

Intricate plot, a lot of math I can't begin to understand but a well made movie!

Compelling performance by Gwyneth Paltrow as a quirky, wounded personality.
