This film was inspired by the true story of mathematician John Forbes Nash, Jr., who was one of three Nobelists celebrated in 1994 for their work in game theory. The film is driven by the agonizing conflict between Nash’s mathematical brilliance and the paranoid schizophrenia which almost destroys both his career and his marriage to Alicia Larde (Jennifer Connelly). The film shows Nash (Russell Crowe) as obsessed and, in schizophrenic episodes, delusional and occasionally violent. He undergoes 1950s insulin shots and later is on and off pills that seem to take away his brilliance along with his schizophrenia.
Late in the film he is off medication and says, in effect, that he has decided not to be deluded by delusions. The film ends with a triumphant series of scenes around the Nobel Prize, including the tribute of his colleagues at Princeton’s Institute for Advanced Study and Nash’s emotional Nobel acceptance speech at Stockholm expressing his gratitude to his wife for standing by him.
