This movie is based on the true story of the brilliant mathematician John Forbes Nash Jr. He made remarkable advancements in the field of mathematics at a young age and had a very promising future. Unfortunately, John Nash had problems deciphering the difference between reality and hallucinations. He had a mental disorder known as Schizophrenia. Schizophrenia is a severe, complex illness that causes hallucinations and can affect a person’s ability to think clearly, manage feelings, make decisions, and relate to others.
From the beginning of the movie it is not hard to find John Nash to be a little eccentric and odd. His social skills were a little off, and he seemed to never really relate to anyone; a potential warning sign of schizophrenia. It was not unusual for a person so bright to exhibit these characteristics, so they were easily written off as quirks by the viewers, and by the characters in the movie. He went on to have a seemingly very eventful life. It appeared that he was hired by the secret service to complete tasks for the government because of his extreme intelligence, and he had befriended a fellow Princeton student named Charles. He also went on to marry Alicia who was a former student of his at MIT that he was quickly intrigued by. Up until the shift in the movie, this was John Nash’s reality.
About in the middle of the story it was revealed that this secret life of his was all just hallucinations, except for Alicia; she was the one real thing he had in his life. His work for the government and his best friend were all fragments of his imagination. He exhibited paranoia, which was thought at first due extremely his risky job, and it was understandable. But in reality, he was paranoid all the time and had such realistic hallucinations because he suffered from schizophrenia. The voices he heard, and his inability to distinguish between reality and his made up life were all characteristics of this mental illness.
