Proof

I watched the DVD "Proof" with Gwyneth Paltrow, Anthony Hopkins and Jake Gyllenhaal. Parts of it were filmed in Chicago. It made me think of the movie "A Beautiful Mind."

Synopsis

A devoted daughter (Gwyneth Paltrow) comes to terms with the death of her father (Anthony Hopkins), a brilliant mathematician whose genius was crippled by mental insanity - and is forced to face her own long-harbored fears and emotions. She adjusts to his death with the help of one of her father's former mathematical students (Jake Gyllenhaal), who searches through her father's notebooks in the hope of discovering a bit of his old brilliance. While coming to terms with the possibility that his genius, which she has inherited, may come at a painful price, her sister (Hope Davis) arrives to help settle their father's affairs.
