Proof (2005 film)

Proof is a 2005 American drama film directed by John Madden and starring Gwyneth Paltrow, Anthony Hopkins, Jake Gyllenhaal, and Hope Davis. It was written by Rebecca Miller, based on David Auburns Pulitzer Prizewinning play of the same title.

Awakened from this dream, Catherine realizes that Hal Jake Gyllenhaal, a former graduate student of Roberts, is still upstairs, reading through Roberts books. Hal believes that somewhere in the gibberish there might be additional products of his mathematical genius. On his way out, he comments on the vast amount of work Robert did. Catherine, suspicious, searches his backpack but finds nothing, but when she picks up Hals coat to give to him, a notebook falls out. He explains that he wanted to give the notebook as a birthday present because it had something written in it about her, not math, her. Hal is forced to leave, giving the notebook as intended, when Catherine calls the police.The next day, for the funeral, Catherines sister Claire Hope Davis arrives in town. A huge contrast to the unkempt Catherine, Claire is an overly put together, neurotic New Yorker. Relations between the sisters are tense, and Catherine cannot stand her sisters constant harping on matters of appearance. Catherine is also upset that Claire didnt care for her father as much as Catherine did in his final years. A series of flashbacks documents Catherines ultimately futile struggle to keep up with her own studies as she takes care of her father. ........
