This is one of those not for everyone, not universally liked, sleepers for me. I will preface this and say I hate Paltrow. Long before Goop I thought she was a terrible actress and now I also think she’s a terrible human. Even with that this is a film I come back to time and again and is a favorite. I understand the main character. I feel her pain and struggle. After countless watches this still always gets a tear and I love it.

Rating: 7/10. 74/100

Proof – Top Grade As motion picture studies of mental illness go, Proof would have to be regarded as one of the better attempts. All central performances are on target with Paltrow and Hopkins pulling out all stops, bringing their father-daughter character's personal dilemmas sharply into believable focus. John Madden's (Mrs Brown '97) assured direction keeps the details and pace in perfect harmony - while milking the nuances of the excellent screenplay (co-written by David Auburn from his Pulitzer Prize-winning play to full potential, at no time does this ever feel stagey. Proof is as entertaining as it is an intelligent observation of characters on the edge of understood normality - struggling to maintain their grip on reality and maintaining a sense of worth within the realm of society, and in this case, the world of mathematics. Production values are superior, featuring cinematography by Award nominated DOP Alwin H. Küchler - while Oscar-winning composer Stephen Warbeck won the Georges Delerue Award for his fine score. Superior entertainment. Note: An in-context, sex scene makes it more recommended for a mature audience.

Proof is an excellent film. It is about the daughter of a brilliant but mentally disturbed mathematician who tries to come to grips with her possible inheritance: his insanity. Gwyneth Paltrow and Anthony Hopkins give amazing performances. The screenplay is well written. John Madden did a great job directing this movie. I enjoyed watching this movie because of the drama and mystery. Proof is a must see.

The worst PG-13 drama ever, LOL!!!!!!!!!!!!!!!

The story wasn't great and there was too much shouting.

12/20..............................................................................................................................................

A puzzling experience that is very thought provoking. Gwenyth Paltrow does the best acting here. Scenes change here in an interesting form so you really got to pay attention to it. Hopkins pre The Father is good here and Jake Gyllenhall is and Hope Davis is. The story is on point, trying to solve a great math problem after a father who loved math passed away and her daughter did love it but lost interest and would be swept up in the past of her Father's math problems. A beautifully done film.

Such a well-made, thought-provoking movie

I don't know if it works better as a stage show but the story didn't work here.

Good story. Unfortunately both sister characters are unlikeable, making almost every scene unpleasant to watch.

This had terrible acting. How are some of these people so famous?

Lovely story!, Gwyneth Kate Paltrow's acting was really good ...

Good movie- could have gone a million places with it- feels slightly incomplete

Proof is a nice little film I rate up mainly on account of the performances and some good moviemaking. Gwyneth Paltrow gives an earnest performance and makes for a sympathetic and believable lead. The other actors are up to par and nicely compliment her character. The film tries to hit a sentimental note, and move the audience with some dramatic scenes. I cannot say it totally comes off, but it comes off well-enough. Proof is a bit like a modern day Bergman film, with similar kind of heart, but is more optimistic.

A movie with a winning formula of beautiful storyline, well-casted actors and actresses, elegantly directed. An inspiring piece where what separates genius and insanity is just a simple trust, when courage means taking just one extra step. A movie that shows there is no proof required, because a beautiful heart and mind is bulletproof.

It started off OK but started to get a bit bizarre!

Entertaining and different take on a love story. Very Good.

The only verb directly comes to mind is "bouleverser". Not in the way that usually sentimental movies tugging on certain threads of emotional cords, but something about the loss and sorrow. I do recognize the life of the mathematicians. It is not important of any particular speciality - math or physics or chemistry -but a life of mind. I am among the truly gifted ones who have their daemons standing and prodding them steadily toward the higher reaches of discovery and even fames, but I did have glimpses of the pure beauty that resides resolutely above the life quotidian. The movie mentioned the imaginary unit "i" as the geek rock bands play in complete silence. I know how this non-existed number (which is the square-root of minus -1) defines the boundary of what is tangible, to what is realm of pure ideas. It may be an inside joke in the movie, but it can mean something very solemn for those of us who had previously pestered our professors with "but it does not exist in reality". It is something we can not know perceptually, yet this pure idea has made much of our electronic technology possible. The crux of the story, I think, lies the conflicting demands of intellect and heart. In the scene where the deranged father forced the daughter to read out his "proof" in the snowing night, I can see something more than the sorrow and suffering, the futile struggle against the disintegrating body, but a sense of affirmation of human bond. Does it really matter that there is a breakthrough in math when there are such two souls linking together against the inclemency of age and disease?

Interesting story about a mathematician who goes crazy and his daughter who tries to keep it together. Pretty good. But Paltrow as 27...?! cmon.
