I've already seen this movie twice, and i think it's so great. while watching it you don't get bored because you're always wondering what will happen next. The movie is about a great mathematician, that thinks that he can solve any problem; Also he's a dreamer, and an inventor, so he began to imagine people but he didn't know, and he thinks they are real. When he's taken to the psychiatrist he's told that he had got schizophrenia and he needed to take some medications, but taking these meds he became useless so he stopped them. he looked for a job but he still was seeing unreal things. His wife was a helpful person in his way to get better, even though all the circumstances she stayed beside him.
