"A Beautiful Mind," remarkably, takes neither road. Adapted from a biography of the same name by Sylvia Nasar, this is the story of John Forbes Nash Jr., the mathematics genius who formulated the concept of game theory, which became a foundation for contemporary economics. During the Cold War, Nash developed schizophrenia and became delusional and paranoid, but recovered and won a 1994 Nobel Prize.
At first, I didn't notice that Nash was insane, was difficult to me understand that Jhon has been suffer schizophrenia, every single part of the movie was real, but in his mind was real, the rest of the people have never seen anyone more than John, it was all an illusion created in his schizophrenic mind, at the end of the movie, when Jhon was internship at the hospital, finally in this episode I could see the truth ....
Personally speaking I think that A Beautiful Mind is a good movie, showed me a reality that a person who is brilliant, but nobody knows what is happening in his insane mind , in his reality.
As the Name said, A Beautiful Mind is beautiful.
